-/* Expand an RFC1035-encoded domain name given by encoded.  The
- * containing message is given by abuf and alen.  The result given by
- * *s, which is set to a NUL-terminated allocated buffer.  *enclen is
- * set to the length of the encoded name (not the length of the
- * expanded name; the goal is to tell the caller how many bytes to
- * move forward to get past the encoded name).
- *
- * In the simple case, an encoded name is a series of labels, each
- * composed of a one-byte length (limited to values between 0 and 63
- * inclusive) followed by the label contents.  The name is terminated
- * by a zero-length label.
- *
- * In the more complicated case, a label may be terminated by an
- * indirection pointer, specified by two bytes with the high bits of
- * the first byte (corresponding to INDIR_MASK) set to 11.  With the
- * two high bits of the first byte stripped off, the indirection
- * pointer gives an offset from the beginning of the containing
- * message with more labels to decode.  Indirection can happen an
- * arbitrary number of times, so we have to detect loops.
- *
- * Since the expanded name uses '.' as a label separator, we use
- * backslashes to escape periods or backslashes in the expanded name.
