These changes produced simplier assembly code and allowed for complete test coverage. Also applied some consistency to the functions that translate the core status codes to POSIX status codes. * posix/src/mutextranslatereturncode.c, posix/src/semaphoretranslatereturncode.c: New files. * posix/src/mutexfromcorestatus.c: Removed.
