were formerly included from timespec.h

gettimer() and setitimer().

* libcsupport/Makefile.am, posix/Makefile.am: Comment out including
files which contain routines which are now provided by the newlib
posix subdirectory. Document a few which come from the unix directory.

* posix/src/timersettime.c: POSIX timers use incorrect repeat interval.
This patch fixes the following problems in timer_settime: 1) Uses
value.it_interval for repeat period. 2) Corrects test for incorrect
value of it_value.tv_nsec (should reject 1000000000).

score/include/rtems/score/coresem.h, score/src/coresemseize.c: This
patch addresses issues on implementation of the timeout on the
following POSIX services. Some of these services incorrectly took a
timeout as a relative time. Others would compute a 0 delta to timeout
if the absolute time and the current time were equal and thus
incorrectly block the caller forever. The root of the confusion is
that POSIX specifies that if the timeout is incorrect (e.g. in the
past, is now, or is numerically invalid), that it does not matter if
the call would succeed without blocking. This is in contrast to RTEMS
programming style where all errors are checked before any critical
sections are entered. This fix implemented a more uniform way of
handling POSIX absolute time timeouts.

operations to using API Allocator Mutex. This moves almost all uses
of the RTEMS Workspace from dispatching disabled to mutex protected
which should improve deterministic behavior. The implementation was
carefully done to allow task create and delete extensions to invoke
more services. In particular, a task delete extension should be able
to do mutex and file operations.

This should help eliminate weird casts between u32 and pointers in
various places. The APIs now have to explicitly call _u32 or _string
versions of helper routines. This should also simplify things and
eliminate the need for ugly casts in some cases.
