* sapi/include/rtems/config.h, sapi/include/rtems/sptables.h: Add
missing field to default multiprocessing configuration table. Also
document fields in Doxygen format.
* sapi/include/confdefs.h, score/src/mpci.c, score/src/objectmp.c,
score/src/objectnametoid.c, score/src/objectnametoidstring.c:
Multiprocessing compiles again and survives initialization. The
recent object name and confdefs.h changes had broken it.
* sapi/include/rtems/fatal.h, score/include/rtems/score/coremutex.h,
score/include/rtems/score/interr.h,
score/inline/rtems/score/thread.inl, score/src/coremutexseize.c:
Modifications to aid in full path testing.

score/src/objectnametoid.c: Convert the Objects_Name type from a
simple type to a union of an unsigned 32 bit integer and a pointer.
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.
* score/src/objectclearname.c, score/src/objectcomparenameraw.c,
score/src/objectcomparenamestring.c, score/src/objectcopynameraw.c,

* libcsupport/include/rtems/malloc.h,
libcsupport/src/malloc.c, libcsupport/src/malloc_initialize.c,
libcsupport/src/malloc_p.h,
libcsupport/src/malloc_statistics_helpers.c: Make sbrk()
support pluggable and optional. This eliminates the need for
heap extend and sbrk in the minimum footprint which is ~2.5K on
the SPARC.
* sapi/include/confdefs.h: Add the following configuration points:
+ CONFIGURE_MALLOC_STATISTICS
+ CONFIGURE_MALLOC_BSP_SUPPORTS_SBRK
* libcsupport/src/malloc_sbrk_helpers.c: New file.
* score/src/threadhandler.c, sapi/src/exshutdown.c:
cannot call _fini via atexit() from rtems_shutdown_executive()
because at the point where rtems_shutdown_executive is called
the C-library is already dead.
Instead, register an atexit(_fini) after calling _init().
* Makefile.am: Added libmisc/shell/shellconfig.h to the installed
header list.
* libmisc/shell/shell_cmdset.c: Let the Initial command add occur
in any order rather than before any commands have been added. Also
made the command's strings be copies rather than references.
* sapi/src/ioregisterdriver.c: Return the I/O initialise calls result.
* sapi/include/confdefs.h, sapi/include/rtems/config.h,
sapi/include/rtems/init.h, sapi/src/exinit.c,
score/include/rtems/system.h, score/src/isr.c: Move
interrupt_stack_size field from CPU Table to Configuration Table.
Eliminate CPU Table from all ports. Delete references to CPU Table in
all forms.

score/src/threadstackallocate.c, score/src/threadstackfree.c,
score/src/wkspace.c: Moved most of the remaining CPU Table fields to
the Configuration Table. This included pretasking_hook,
predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace,
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.
* sapi/src/exinit.c, score/include/rtems/score/object.h,
score/include/rtems/score/thread.h, score/src/object.c,
score/src/thread.c: Conditionally compile out more code that is
specific to multiprocessor configurations.
* sapi/src/exinit.c, score/Makefile.am,
score/include/rtems/score/apimutex.h: API Mutex calls should never
have been inlined. Inlining them lead to many inlined copies of core
mutex lock. This lead to over 2K savings in the SPARC/ERC32
minimum.exe.
* score/src/apimutex.c, score/src/apimutexallocate.c,
score/src/apimutexlock.c, score/src/apimutexunlock.c: New files.
* sapi/Makefile.am, sapi/include/rtems/io.h, sapi/src/io.c: Split into
one function per file execpt io.c which contains required
initialization methods.
* sapi/src/ioclose.c, sapi/src/iocontrol.c, sapi/src/iodata.c,
sapi/src/ioinitialize.c, sapi/src/ioopen.c, sapi/src/ioread.c,
sapi/src/ioregisterdriver.c, sapi/src/iounregisterdriver.c,
sapi/src/iowrite.c: New files.
* sapi/include/confdefs.h, sapi/src/io.c: Readded code to copy driver
table into Workspace but now it is only done if the application needs
extra slots for dynamic driver registration. Cleaned up
rtems_io_register_driver and rtems_io_unregister_driver code and
added numerous error cases to register.
* libmisc/Makefile.am, libmisc/monitor/mon-object.c,
libmisc/monitor/monitor.h, sapi/include/confdefs.h,
sapi/include/rtems/config.h, sapi/include/rtems/io.h,
sapi/src/exinit.c, sapi/src/io.c: Eliminate maximum_drivers
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.
* rtems/src/region.c, sapi/src/exinit.c: Now that the Region is
an optional manager, we cannot depend on it do initialize the
internal Allocator Mutex. This was always a questionable place to
do it, so this is a cleanup.
* libcsupport/include/rtems/libcsupport.h, libcsupport/src/newlibc.c,
sapi/Makefile.am, sapi/include/confdefs.h, sapi/src/exinit.c,
score/Makefile.am, score/preinstall.am,
score/include/rtems/score/userext.h, score/src/chain.c,
score/src/userext.c: Switch to newlib reentrancy extension being
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.

* ChangeLog, libcsupport/src/malloc.c,
libcsupport/src/mallocfreespace.c, sapi/include/confdefs.h,
score/Makefile.am, score/preinstall.am: malloc never blocks so the
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.
