	* posix/src/mqueuenametoid.c,
	posix/src/semaphorenametoid.c: Removed files.
	* posix/src/psxnametoid.c: New file.
	* posix/Makefile.am: Reflect changes above.
	* posix/include/rtems/posix/config.h: Fixed integer types.
	* posix/include/rtems/posix/posixapi.h: Declare _POSIX_Name_to_id().
	* posix/include/rtems/posix/mqueue.h,
	posix/inline/rtems/posix/mqueue.inl: Changed parameter of
	_POSIX_Message_queue_Create_support().
	_POSIX_Message_queue_Name_to_id() is now inline.
	* posix/include/rtems/posix/semaphore.h,
	posix/inline/rtems/posix/semaphore.inl: Changed parameter of
	_POSIX_Semaphore_Create_support().  _POSIX_Semaphore_Name_to_id() is
	now inline.
	* posix/src/mqueuecreatesupp.c, posix/src/semaphorecreatesupp.c: Use
	_Workspace_String_duplicate().
	* posix/src/mqueuesendsupp.c, posix/src/mqueueopen.c,
	posix/src/mqueueunlink.c, posix/src/seminit.c, posix/src/semopen.c,
	posix/src/semunlink.c: Update due to API changes.
