 Provide pthread_[f]chdir_np() functions for 10.5+.

 This provides both missing prototypes and missing function wrappers
 for the pthread_[f]chdir_np() functions, which were introduced as
 syscalls in 10.5, but not provided as functions until 10.12, and
 not provided as prototypes at all in any SDK.

 At present, no SDK for any OS version provides prototypes for these
 functions, even when the functions themselves are included in
 libSystem.  For that reason, we condition the addition of the
 prototypes on the flag _MACPORTS_LEGACY_PTHREAD_CHDIR.  This is
 ignored in the 10.4 SDK, since the functions themselves are not
 available in 10.4.

 The missing function wrappers are provided for 10.5-10.11.  For 10.4,
 dummy functions that always fail are provided, though no SDK
 declarations are present in the 10.4 SDK, even with the enabling flag.

 Closes: https://trac.macports.org/ticket/71265

 TESTED:
 Passes all tests on all platforms, including the new test.
