* configure.ac, score/inline/rtems/score/thread.inl,
score/src/threaddispatch.c: Add ability for user to disable inlining
of _Thread_Enable_dispatch. This can save code space but more
importantly it means the binary generated does not have code inlined
that is difficult to test and very seldom executed.

* score/Makefile.am, score/include/rtems/score/thread.h,
score/inline/rtems/score/thread.inl: No longer inline _Thread_Get. It
resulted in unnessary code explosion, many uncovered paths when
looking at binary executable coverage, and only optimized getting
self. Id translations were still getting pushed to a subroutine call
to _Objects_Get. Later the non-inlined version can be further
optimized to get Ids in range for the current API, then self, then
look at other APIs.

Large patch to improve Doxygen output. As a side-effect, grammar and

* 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.

Move the C library re-enterrant support directly into
the thread dispatch code. RTEMS needs libc and so requiring
libc to use a user extension with its overhead is not the best
solution. This patch lowers the overhead to 2 pointer moves.

a BSP (c4xsim) supporting the simulator included with gdb. This port
was done by Joel Sherrill and Jennifer Averett of OAR Corporation.
Also included with this port is a space/time optimization to eliminate
FP context switch management on CPUs without hardware or software FP.
An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8)
on this CPU. This required addressing alignment checks and assumptions
as well as fixing code that assumed sizeof(unsigned32) == 4.

the inline implementation. The impetus for this was twofold. First,
it is incorrect to have static inline prototypes when using the macro
implementation. Second, this reduced the number of lines in the include
files seen by rtems.h by about 2000 lines.
Next we restricted visibility for the inline routines to inside the
executive itself EXCEPT for a handful of objects. This reduced the
number of include files included by rtems.h by 40 files and reduced
the lines in the include files seen by rtems.h by about 6000 lines.
In total, these reduced the compile time of the entire RTEMS tree by 20%.
This results in about 8 minutes savings on the SparcStation 10 morgana.

the thread handler (IDLE), MPCI object (SYSI now MP Receive)
and initialize_executive_early (IO initialization). The SYSI task
no longer exists in a single processor configuration. This reduces
single processor Workspace requirements by a TCB and a stack which
is often larger than the minimum stack size. Moving the IO initialization
plus accompanying BSP hooks eliminated an initialization ordering problem
in which a global task could be created before the MPCI was initialized.

Configuration Table Template file added and all tests
modified to use this. All gvar.h and conftbl.h files
removed from test directories.
Configuration parameter maximum_devices added.
Core semaphore and mutex handlers added and RTEMS API Semaphore
Manager updated to reflect this.
Initialization sequence changed to invoke API specific initialization
routines. Initialization tasks table now owned by RTEMS Tasks Manager.
Added user extension for post-switch.
Utilized user extensions to implement API specific functionality
like signal dispatching.
Added extensions to the System Initialization Thread so that an
API can register a function to be invoked while the system
is being initialized. These are largely equivalent to the
pre-driver and post-driver hooks.
Added the Modules file oar-go32_p5, modified oar-go32, and modified
the file make/custom/go32.cfg to look at an environment varable which
determines what CPU model is being used.
All BSPs updated to reflect named devices and clock driver's IOCTL
used by the Shared Memory Driver. Also merged clock isr into
main file and removed ckisr.c where possible.
Updated spsize to reflect new and moved variables.
Makefiles for the executive source and include files updated to show
break down of files into Core, RTEMS API, and Neither.
Header and inline files installed into subdirectory based on whether
logically in the Core or a part of the RTEMS API.

Added a table of object information control blocks.
Modified _Thread_Get so it looks up a thread regardless of which
thread management "entity" (manager, internal, etc) actually "owns" it.
