extra_mpci_receive_server_stack, stack_allocate_hook, and
stack_free_hook. As a side-effect of this effort some multiprocessing
code was made conditional and some style clean up occurred.

extra slots for dynamic driver registration. Cleaned up

added numerous error cases to register.

configuration parameter since it was used to configure a no longer
used feature. Device names are now part of the filesystem not in a
table. This also eliminated the variables _IO_Number_of_devices and
_IO_Driver_name_table from RTEMS as well as the memory allocation
used to populate _IO_Driver_name_table.
* libmisc/monitor/mon-dname.c: Removed.
* sapi/include/confdefs.h: Add CONFIGURE_MESSAGE_BUFFER_MEMORY so there
is less dependence on CONFIGURE_MEMORY_OVERHEAD. Do not arbitrarily
add 1 to CONFIGURE_MEMORY_OVERHEAD so we do not waste a kilobyte for
unused Workspace. Round the workspace required size to an 8 byte
boundary instead of a 0x400 byte one. We may end up needing to add 8
bytes again to account for the alignment rounding.

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.

* Mega patch merge to change the format of the object IDs to
loosen the dependency between the SCORE and the various APIs.
There was considerable work to simplify the object name management
and it appears that the name_table field is no longer needed.
This patch also includes the addition of the internal mutex
which is currently only used to protect some types of allocation
and deallocation. This significantly can reduce context
switch latency under certain circumstances. In particular,
some heap/region operations were O(n) and had dispatching
disabled. This should help enormously. With this merge,
the patch is not as clean as it should be. In particular,
the documentation has not been modified to reflect the new object
ID layout, the IDs in the test screens are not updated, and
_Objects_Get_information needs to be a real routine not inlined.
As part of this patch a lot of MP code for thread/proxy blocking
was made conditional and cleaned up.
* include/confdefs.h, src/exinit.c, src/extension.c, src/itronapi.c,
src/posixapi.c, src/rtemsapi.c: Modified as part of above.
* PR132 requested some tinkering ot lower memory.
* include/confdefs.h: Lowered footprint of device driver table
and statically configure user extensions. Now if no static
extensions are configured, then the table is not instantiated.
* include/confdefs.h, include/rtems/config.h, include/rtems/io.h,
optman/no-io.c, src/exinit.c, src/io.c: Added a device driver
register/unregister interface to allow device drivers to be
installed and removed at runtime. This means you do not need devices
present in the device table when you build.
