* 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.

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.

blocking sends when the queue is full. The SuperCore was enhanced
to support blocking on send. The existing POSIX API was debugged
and numerous test cases were added to psxmsgq01 by Jennifer Averett.
SuperCore enhancements and resulting modifications to other APIs
were done by Joel.
There is one significant point of interpretation for the POSIX API.
What happens to threads already blocked on a message queue when the
mode of that same message queue is changed from blocking to non-blocking?
We decided to unblock all waiting tasks with an EAGAIN error just
as if a non-blocking version of the same operation had returned
unsatisfied. This case is not discussed in the POSIX standard and
other implementations may have chosen differently.

power binary/mutex style semaphores already supported by RTEMS. This
was done at the request of Eric Norum <eric@cls.usask.ca> in support
of his effort to port EPICS to RTEMS. This change consisted of
changing the nesting_allowed boolean into a lock_nesting_behavior
enumerated value as well as allowing the core mutex object to optionally
support ensuring that the holder of a binary semaphore released it.
Finally, a more subtle enhancement was to allow the non-holder to release
a priority inheritance/ceiling mutex and still allow the holding task
to return to its original priority.

First, the unlimited patch. I have compiled the unlmited patch for the
Linux posix BSP only and it seems to work cleanly. I would like a really
major application run on this change before commiting as the changes are
very core and significant. I am currently building all the tests to run.
I have no targets suitable to test on at the moment.
I have tested the patch for inline functions and macros.
Turning macros on has found some core bugs. I have fixed these but have
not run all the tests. Please review the patch for these changes. They
are:
1) The conditional compilation for MP support broke the core messages
code. You cannot embed a conditional macro in another macro. The Send
and Urgent Send calls are macros.
2) User extensions handler initialisation now has two parameters. I have
updated the macros to support the extra parameter.
The patch also contains the gcc-target-default.cfg fix required to build
the kernel. More of a by product than a fix for you.

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.

single biggest changes were the expansion of the workspace size
macro to include other types of objects and the increase in the
minimum stack size for most CPUs.
