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.
