* libcsupport/src/libio.c: rtems_libio_allocate:
rtems_libio_iop_freelist incorrectly zeroed on semaphore error. Now
checks error and does not modify anything until sure it has created
semaphore.

sapi/src/itronapi.c, sapi/src/posixapi.c: Make changes necessary for
all tests to run on SPARC with 16-bit Ids. This required ensuring
that all POSIX and compilering binding code makes a distinction
between the public Id type (e.g. pthread_t, etc.) and the RTEMS
Object_Id type. All POSIX Object Get routines should not take the
POSIX Id type as the argument. Sixteen bit RTEMS Ids should be placed
into the 32-bits reserved by the POSIX API type in a uniform manner
now. This removed all assumptions that the external Id types in POSIX
and ITRON are the same as the internal Object Id type.

SuperCore handler Timestamp to provide an opaque class for the

difference between two timestamps. By using SuperCore Timestamp, it
is clear which methods and APIs really have to be struct timespec and
