+Conversions between UTF32, UTF-16, and UTF-8. Source code file.
+Author: Mark E. Davis, 1994.
+Rev History: Rick McGowan, fixes & updates May 2001.
+Sept 2001: fixed const & error conditions per
+mods suggested by S. Parent & A. Lillich.
+June 2002: Tim Dodd added detection and handling of incomplete
+source sequences, enhanced error detection, added casts
+to eliminate compiler warnings.
+July 2003: slight mods to back out aggressive FFFE detection.
+Jan 2004: updated switches in from-UTF8 conversions.
+Oct 2004: updated to use UNI_MAX_LEGAL_UTF32 in UTF-32 conversions.
+
+See the header file "ConvertUTF.h" for complete documentation.

+
+Conversions between UTF32, UTF-16, and UTF-8.  Header file.
+
+Several funtions are included here, forming a complete set of
+conversions between the three formats.  UTF-7 is not included
+here, but is handled in a separate source file.
+
+Each of these routines takes pointers to input buffers and output
+buffers.  The input buffers are const.
+
+Each routine converts the text between *sourceStart and sourceEnd,
+putting the result into the buffer between *targetStart and
+targetEnd. Note: the end pointers are *after* the last item: e.g.
+*(sourceEnd - 1) is the last item.
+
+The return result indicates whether the conversion was successful,
+and if not, whether the problem was in the source or target buffers.
+(Only the first encountered problem is indicated.)
+
+After the conversion, *sourceStart and *targetStart are both
+updated to point to the end of last text successfully converted in
+the respective buffers.
+
+Input parameters:
+sourceStart - pointer to a pointer to the source buffer.
+The contents of this are modified on return so that
+it points at the next thing to be converted.
+targetStart - similarly, pointer to pointer to the target buffer.
+sourceEnd, targetEnd - respectively pointers to the ends of the
+two buffers, for overflow checking only.
+
+These conversion functions take a ConversionFlags argument. When this
+flag is set to strict, both irregular sequences and isolated surrogates
+will cause an error.  When the flag is set to lenient, both irregular
+sequences and isolated surrogates are converted.
+
+Whether the flag is strict or lenient, all illegal sequences will cause
+an error return. This includes sequences such as: <F4 90 80 80>, <C0 80>,
+or <A0> in UTF-8, and values above 0x10FFFF in UTF-32. Conformant code
+must check for illegal sequences.
+
+When the flag is set to lenient, characters over 0x10FFFF are converted
+to the replacement character; otherwise (when the flag is set to strict)
+they constitute an error.
+
+Output parameters:
+The value "sourceIllegal" is returned from some routines if the input
+sequence is malformed.  When "sourceIllegal" is returned, the source
+value will point to the illegal value that caused the problem. E.g.,
+in UTF-8 when a sequence is malformed, it points to the start of the
+malformed sequence.

+
+// dwarf2reader::CompilationUnit is a simple and direct parser for
+// DWARF data, but its handler interface is not convenient to use.  In
+// particular:
+//
+// - CompilationUnit calls Dwarf2Handler's member functions to report
+//   every attribute's value, regardless of what sort of DIE it is.
+//   As a result, the ProcessAttributeX functions end up looking like
+//   this:
+//
+//     switch (parent_die_tag) {
+//       case DW_TAG_x:
+//         switch (attribute_name) {
+//           case DW_AT_y:
+//             handle attribute y of DIE type x
+//           ...
+//         } break;
+//       ...
+//     } 
+//
+//   In C++ it's much nicer to use virtual function dispatch to find
+//   the right code for a given case than to switch on the DIE tag
+//   like this.
+//
+// - Processing different kinds of DIEs requires different sets of
+//   data: lexical block DIEs have start and end addresses, but struct
+//   type DIEs don't.  It would be nice to be able to have separate
+//   handler classes for separate kinds of DIEs, each with the members
+//   appropriate to its role, instead of having one handler class that
+//   needs to hold data for every DIE type.
+//
+// - There should be a separate instance of the appropriate handler
+//   class for each DIE, instead of a single object with tables
+//   tracking all the dies in the compilation unit.
+//
+// - It's not convenient to take some action after all a DIE's
+//   attributes have been seen, but before visiting any of its
+//   children.  The only indication you have that a DIE's attribute
+//   list is complete is that you get either a StartDIE or an EndDIE
+//   call.
+//
+// - It's not convenient to make use of the tree structure of the
+//   DIEs.  Skipping all the children of a given die requires
+//   maintaining state and returning false from StartDIE until we get
+//   an EndDIE call with the appropriate offset.
+//
+// This interface tries to take care of all that.  (You're shocked, I'm sure.)
+//
+// Using the classes here, you provide an initial handler for the root
+// DIE of the compilation unit.  Each handler receives its DIE's
+// attributes, and provides fresh handler objects for children of
+// interest, if any.  The three classes are:
+//
+// - DIEHandler: the base class for your DIE-type-specific handler
+//   classes.
+//
+// - RootDIEHandler: derived from DIEHandler, the base class for your
+//   root DIE handler class.
+//
+// - DIEDispatcher: derived from Dwarf2Handler, an instance of this
+//   invokes your DIE-type-specific handler objects.
+//
+// In detail:
+//
+// - Define handler classes specialized for the DIE types you're
+//   interested in.  These handler classes must inherit from
+//   DIEHandler.  Thus:
+//
+//     class My_DW_TAG_X_Handler: public DIEHandler { ... };
+//     class My_DW_TAG_Y_Handler: public DIEHandler { ... };
+//
+//   DIEHandler subclasses needn't correspond exactly to single DIE
+//   types, as shown here; the point is that you can have several
+//   different classes appropriate to different kinds of DIEs.
+//
+// - In particular, define a handler class for the compilation
+//   unit's root DIE, that inherits from RootDIEHandler:
+//
+//     class My_DW_TAG_compile_unit_Handler: public RootDIEHandler { ... };
+//
+//   RootDIEHandler inherits from DIEHandler, adding a few additional
+//   member functions for examining the compilation unit as a whole,
+//   and other quirks of rootness.
+//
+// - Then, create a DIEDispatcher instance, passing it an instance of
+//   your root DIE handler class, and use that DIEDispatcher as the
+//   dwarf2reader::CompilationUnit's handler:
+//
+//     My_DW_TAG_compile_unit_Handler root_die_handler(...);
+//     DIEDispatcher die_dispatcher(&root_die_handler);
+//     CompilationUnit reader(sections, offset, bytereader, &die_dispatcher);
+//
+//   Here, 'die_dispatcher' acts as a shim between 'reader' and the
+//   various DIE-specific handlers you have defined.
+//
+// - When you call reader.Start(), die_dispatcher behaves as follows,
+//   starting with your root die handler and the compilation unit's
+//   root DIE:
+//
+//   - It calls the handler's ProcessAttributeX member functions for
+//     each of the DIE's attributes.
+//
+//   - It calls the handler's EndAttributes member function.  This
+//     should return true if any of the DIE's children should be
+//     visited, in which case:
+//
+//     - For each of the DIE's children, die_dispatcher calls the
+//       DIE's handler's FindChildHandler member function.  If that
+//       returns a pointer to a DIEHandler instance, then
+//       die_dispatcher uses that handler to process the child, using
+//       this procedure recursively.  Alternatively, if
+//       FindChildHandler returns NULL, die_dispatcher ignores that
+//       child and its descendants.
+// 
+//   - When die_dispatcher has finished processing all the DIE's
+//     children, it invokes the handler's Finish() member function,
+//     and destroys the handler.  (As a special case, it doesn't
+//     destroy the root DIE handler.)
+// 
+// This allows the code for handling a particular kind of DIE to be
+// gathered together in a single class, makes it easy to skip all the
+// children or individual children of a particular DIE, and provides
+// appropriate parental context for each die.

+// where to find the saved values of the caller's registers (if the
+// callee has stashed them somewhere to free up the registers for its
+// own use).
+//
+// For example, suppose we have a function whose machine code looks
+// like this (imagine an assembly language that looks like C, for a
+// machine with 32-bit registers, and a stack that grows towards lower
+// addresses):
+//
+// func:                                ; entry point; return address at sp
+// func+0:      sp = sp - 16            ; allocate space for stack frame
+// func+1:      sp[12] = r0             ; save r0 at sp+12
+// ...                                  ; other code, not frame-related
+// func+10:     sp -= 4; *sp = x        ; push some x on the stack
+// ...                                  ; other code, not frame-related
+// func+20:     r0 = sp[16]             ; restore saved r0
+// func+21:     sp += 20                ; pop whole stack frame
+// func+22:     pc = *sp; sp += 4       ; pop return address and jump to it
+//
+// DWARF CFI is (a very compressed representation of) a table with a
+// row for each machine instruction address and a column for each
+// register showing how to restore it, if possible.
+//
+// A special column named "CFA", for "Canonical Frame Address", tells how
+// to compute the base address of the frame; registers' entries may
+// refer to the CFA in describing where the registers are saved.
+//
+// Another special column, named "RA", represents the return address.
+//
+// For example, here is a complete (uncompressed) table describing the
+// function above:
+// 
+//     insn      cfa    r0      r1 ...  ra
+//     =======================================
+//     func+0:   sp                     cfa[0]
+//     func+1:   sp+16                  cfa[0] 
+//     func+2:   sp+16  cfa[-4]         cfa[0]
+//     func+11:  sp+20  cfa[-4]         cfa[0]
+//     func+21:  sp+20                  cfa[0]
+//     func+22:  sp                     cfa[0]
+//
+// Some things to note here:
+//
+// - Each row describes the state of affairs *before* executing the
+//   instruction at the given address.  Thus, the row for func+0
+//   describes the state before we allocate the stack frame.  In the
+//   next row, the formula for computing the CFA has changed,
+//   reflecting that allocation.
+//
+// - The other entries are written in terms of the CFA; this allows
+//   them to remain unchanged as the stack pointer gets bumped around.
+//   For example, the rule for recovering the return address (the "ra"
+//   column) remains unchanged throughout the function, even as the
+//   stack pointer takes on three different offsets from the return
+//   address.
+//
+// - Although we haven't shown it, most calling conventions designate
+//   "callee-saves" and "caller-saves" registers. The callee must
+//   preserve the values of callee-saves registers; if it uses them,
+//   it must save their original values somewhere, and restore them
+//   before it returns. In contrast, the callee is free to trash
+//   caller-saves registers; if the callee uses these, it will
+//   probably not bother to save them anywhere, and the CFI will
+//   probably mark their values as "unrecoverable".
+//
+//   (However, since the caller cannot assume the callee was going to
+//   save them, caller-saves registers are probably dead in the caller
+//   anyway, so compilers usually don't generate CFA for caller-saves
+//   registers.)
+// 
+// - Exactly where the CFA points is a matter of convention that
+//   depends on the architecture and ABI in use. In the example, the
+//   CFA is the value the stack pointer had upon entry to the
+//   function, pointing at the saved return address. But on the x86,
+//   the call frame information generated by GCC follows the
+//   convention that the CFA is the address *after* the saved return
+//   address.
+//
+//   But by definition, the CFA remains constant throughout the
+//   lifetime of the frame. This makes it a useful value for other
+//   columns to refer to. It is also gives debuggers a useful handle
+//   for identifying a frame.
+//
+// If you look at the table above, you'll notice that a given entry is
+// often the same as the one immediately above it: most instructions
+// change only one or two aspects of the stack frame, if they affect
+// it at all. The DWARF format takes advantage of this fact, and
+// reduces the size of the data by mentioning only the addresses and
+// columns at which changes take place. So for the above, DWARF CFI
+// data would only actually mention the following:
+// 
+//     insn      cfa    r0      r1 ...  ra
+//     =======================================
+//     func+0:   sp                     cfa[0]
+//     func+1:   sp+16
+//     func+2:          cfa[-4]
+//     func+11:  sp+20
+//     func+21:         r0
+//     func+22:  sp            
+//
+// In fact, this is the way the parser reports CFI to the consumer: as
+// a series of statements of the form, "At address X, column Y changed
+// to Z," and related conventions for describing the initial state.
+//
+// Naturally, it would be impractical to have to scan the entire
+// program's CFI, noting changes as we go, just to recover the
+// unwinding rules in effect at one particular instruction. To avoid
+// this, CFI data is grouped into "entries", each of which covers a
+// specified range of addresses and begins with a complete statement
+// of the rules for all recoverable registers at that starting
+// address. Each entry typically covers a single function.
+//
+// Thus, to compute the contents of a given row of the table --- that
+// is, rules for recovering the CFA, RA, and registers at a given
+// instruction --- the consumer should find the entry that covers that
+// instruction's address, start with the initial state supplied at the
+// beginning of the entry, and work forward until it has processed all
+// the changes up to and including those for the present instruction.
+//
+// There are seven kinds of rules that can appear in an entry of the

+  // address size set properly. Report the data we find to HANDLER.
+  //
+  // This class can also parse Linux C++ exception handling data, as found
+  // in '.eh_frame' sections. This data is a variant of DWARF CFI that is
+  // placed in loadable segments so that it is present in the program's
+  // address space, and is interpreted by the C++ runtime to search the
+  // call stack for a handler interested in the exception being thrown,
+  // actually pop the frames, and find cleanup code to run.
+  //
+  // There are two differences between the call frame information described
+  // in the DWARF standard and the exception handling data Linux places in
+  // the .eh_frame section:
+  //
+  // - Exception handling data uses uses a different format for call frame
+  //   information entry headers. The distinguished CIE id, the way FDEs
+  //   refer to their CIEs, and the way the end of the series of entries is
+  //   determined are all slightly different.
+  //
+  //   If the constructor's EH_FRAME argument is true, then the
+  //   CallFrameInfo parses the entry headers as Linux C++ exception
+  //   handling data. If EH_FRAME is false or omitted, the CallFrameInfo
+  //   parses standard DWARF call frame information.
+  //
+  // - Linux C++ exception handling data uses CIE augmentation strings
+  //   beginning with 'z' to specify the presence of additional data after
+  //   the CIE and FDE headers and special encodings used for addresses in
+  //   frame description entries.
+  //
+  //   CallFrameInfo can handle 'z' augmentations in either DWARF CFI or
+  //   exception handling data if you have supplied READER with the base
+  //   addresses needed to interpret the pointer encodings that 'z'
+  //   augmentations can specify. See the ByteReader interface for details
+  //   about the base addresses. See the CallFrameInfo::Handler interface
+  //   for details about the additional information one might find in
+  //   'z'-augmented data.
+  //
+  // Thus:
+  //
+  // - If you are parsing standard DWARF CFI, as found in a .debug_frame
+  //   section, you should pass false for the EH_FRAME argument, or omit
+  //   it, and you need not worry about providing READER with the
+  //   additional base addresses.
+  //
+  // - If you want to parse Linux C++ exception handling data from a
+  //   .eh_frame section, you should pass EH_FRAME as true, and call
+  //   READER's Set*Base member functions before calling our Start method.
+  //
+  // - If you want to parse DWARF CFI that uses the 'z' augmentations
+  //   (although I don't think any toolchain ever emits such data), you
+  //   could pass false for EH_FRAME, but call READER's Set*Base members.
+  //
+  // The extensions the Linux C++ ABI makes to DWARF for exception

+// DISCUSSION:
+//
+// The three main classes of interest are
+//
+//  MachMessage:    a wrapper for a mach message of the following form
+//   mach_msg_header_t
+//   mach_msg_body_t
+//   optional descriptors
+//   optional extra message data
+//
+//  MachReceiveMessage and MachSendMessage subclass MachMessage
+//    and are used instead of MachMessage which is an abstract base class
+//
+//  ReceivePort:
+//    Represents a mach port for which we have receive rights
+//
+//  MachPortSender:
+//    Represents a mach port for which we have send rights
+//
+// Here's an example to receive a message on a server port:
+//
+//        // This creates our named server port
+//        ReceivePort receivePort("com.Google.MyService");
+//
+//        MachReceiveMessage message;
+//        kern_return_t result = receivePort.WaitForMessage(&message, 0);
+//
+//        if (result == KERN_SUCCESS && message.GetMessageID() == 57) {
+//          mach_port_t task = message.GetTranslatedPort(0);
+//          mach_port_t thread = message.GetTranslatedPort(1);
+//
+//          char *messageString = message.GetData();
+//
+//          printf("message string = %s\n", messageString);
+//        }
+//
+// Here is an example of using these classes to send a message to this port:
+//
+//    // send to already named port
+//    MachPortSender sender("com.Google.MyService");
+//    MachSendMessage message(57);      // our message ID is 57
+//
+//    // add some ports to be translated for us
+//    message.AddDescriptor(mach_task_self());     // our task
+//    message.AddDescriptor(mach_thread_self());   // this thread
+//
+//    char messageString[] = "Hello server!\n";
+//    message.SetData(messageString, strlen(messageString)+1);

+//
+// The problem:
+// -------------
+// Let's say you want to build this code in an environment where a global
+// string type is defined (i.e. ::string).  Now, let's suppose that ::string
+// is different that std::string and you'd like to have the option to easily
+// choose between the two string types.  Ideally you'd like to control which
+// string type is chosen by simply #defining an identifier.
+//
+// The solution:
+// -------------
+// #define HAS_GLOBAL_STRING somewhere in a global header file and then
+// globally replace std::string with string.  Then include this header
+// file everywhere where string is used.  If you want to revert back to
+// using std::string, simply remove the #define (HAS_GLOBAL_STRING).
