Refactoring of priority handling, to isolate the bitmap
implementation of priorities in the supercore so that priority
management is a little more modular. This change is in anticipation
of scheduler implementations that can select how they manage tracking
priority levels / finding the highest priority ready task. Note that
most of the changes here are simple renaming, to clarify the use of
the bitmap-based priority management.

copies of essentially the same hard to test critical section code
becoming the one shared routine _Thread_blocking_operation_Cancel. In
addition, the thread queue and event code now share a common
synchronization enumerated type. Along the way, switches were

copyrights were updated.

installed in the initial set instead of using rtems_extension_create.
While implementing this, noticed that user extensions and chain code
had multiple functions in a single file which is not desirable in the
SuperCore and API portions of RTEMS, so split these into multiple
files with one function per file. Also noticed that some of user
extension code was inlined for no particular reason so moved that to
C bodies. Split executive shutdown from initialization since not
every application shuts down. Moved __fini call to executive shutdown
to be more symmetrical with where it is called at startup.

Region Manager is quite heavy for implementing this. This patch
implements the C Program Heap directly in terms of the new Protected
Heap handler. This handler is a direct use of a SuperCore Heap in
conjunction with the Allocator Mutex used internally by RTEMS. This
saves 3184 bytes on most SPARC test executables.

This lead to significant cleanup in the API routines and eliminated
some of the same code from the POSIX API. At this point, the
SuperCore keeps time in POSIX timespec format properly from 1970. You
just cannot set it before 1988 in keeping with RTEMS traditional
behavior.
