Statically allocate the objects information together with the initial
set of objects either via <rtems/confdefs.h>. Provide default object
informations with zero objects via librtemscpu.a. This greatly
simplifies the workspace size estimate. RTEMS applications which do not
use the unlimited objects option are easier to debug since all objects
reside now in statically allocated objects of the right types.
Close#3621.
Use the maximum ID for the ID to object translation. Using the maximum
ID gets rid of an additional load from the object information in
_Objects_Get(). In addition, object lookups fail for every ID in case
the object information is cleared to zero. This makes it a bit more
robust during system startup (see new tests in spconfig02).
The local table no longer needs a NULL pointer entry at array index
zero. Adjust all the object iteration loops accordingly.
Remove Objects_Information::minimum_id since it contains only redundant
information. Add _Objects_Get_minimum_id() to get the minimum ID.
Update #3621.
Rename Objects_Information::allocation_size in
Objects_Information::objects_per_block. Adjust integer types in
_Objects_Shrink_information() and _Objects_Free().
Update #3621.
Rename Objects_Information::size to Objects_Information::object_size.
Change its type from size_t to uint16_t and move it to reduce the size
of Objects_Information.
Update #3621.
Enable support for string objects names unconditionally. Add const
qualifier throughout. Split _Objects_Namespace_remove() into
_Objects_Namespace_remove_u32() and _Objects_Namespace_remove_string()
to avoid an unnecessary dependency on _Workspace_Free().
Update #2514.
The fatal is internal indicator is redundant since the fatal source and
error code uniquely identify a fatal error. Keep the fatal user
extension is internal parameter for backward compatibility and set it to
false always.
Update #2825.
Remove unused supports_global parameter. Convert
_Objects_Initialize_information() to a macro to avoid use of
RTEMS_MULTIPROCESSING define for each caller.
Move implementation specific parts of object.h and object.inl into new
header file objectimpl.h. The object.h contains now only the
application visible API.
Move implementation specific parts of chain.h and chain.inl into new
header file chainimpl.h. The chain.h contains now only the application
visible API.

* 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.
