Log Message:
-----------
Add configure options to point the build at Apple libc and XNU source,
required to find private headers on Mac OS X.
Use AC_ARG_ENABLE instead of AC_ARG_WITH for functional frobs, such as
legacy API, libdispatch_init constructor tagging, Apple-specific TSD
and semaphore optimizations, as well as new settings such as the use of
crashreporter_info.
Locate MIG on Mac OS X, as we need it to build protocols.def.
Use pthread_workqueue.h to decide whether to define
HAVE_PTHREAD_WORKQUEUES. We may want to offer a --disable frob for this
on Mac OS X.
