Support application-supplied logging
This adds a method to set a logging callback. If such a callback is
set, all SWIFT_LOG calls will invoke this callback instead of writing to
either stderr or the swift logging file.
Test-Information:
Updated unit tests pass.
Checked that logs generated by Swift and Sluift (which do not set the
callback) resulted in logging in the expected location.
