* sapi/src/exinit.c, score/Makefile.am,
score/include/rtems/score/apimutex.h: API Mutex calls should never
have been inlined. Inlining them lead to many inlined copies of core
mutex lock. This lead to over 2K savings in the SPARC/ERC32
minimum.exe.
* score/src/apimutex.c, score/src/apimutexallocate.c,
score/src/apimutexlock.c, score/src/apimutexunlock.c: New files.
