* sapi/include/rtems/init.h, sapi/src/exinit.c: Refactored and renamed
initialization routines to rtems_initialize_data_structures,
rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
rtems_initialize_start_multitasking. This opened the sequence up so
that bootcard() could provide a more robust and flexible framework
which is easier to explain and understand. This also lays the
groundwork for sharing the division of available memory between the
RTEMS workspace and heap and the C library initialization across all
BSPs.

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.

Instead, register an atexit(_fini) after calling _init().

extra_mpci_receive_server_stack, stack_allocate_hook, and

added numerous error cases to register.

configuration parameter since it was used to configure a no longer

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.
* rtems/src/region.c, sapi/src/exinit.c: Now that the Region is

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.

* src/extensionident.c: Added ID to name lookup service and changed
name of id/name translation status code. This propagated to multiple
functions. The user API service added was rtems_object_id_to_name()
* Jump table for single entry point removed.
* include/rtems/directives.h, src/entrytable.c: Removed.
* include/Makefile.am, src/Makefile.am, src/exinit.c: Modified to
reflect above.
* 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.
* src/exinit.c: Slightly rework initialization so there
is a valid thread as _Thread_Executing when the pre_tasking
hook is called. This allows one directives and malloc
to potentially use mutex protection.
* 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.
