score/inline/rtems/score/thread.inl: Add support for optionally
having a unified work area. In other words, the RTEMS Workspace and C
Program Heap are the same pool of memory.
* 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.

score/include/rtems/score/heap.h, score/src/heapgetinfo.c: Add
capability to return information about just the free blocks in a
region or heap. Also changed the semantics of free space available
to be the largest block of memory that can be allocated.
* rtems/src/regiongetfreeinfo.c, score/src/heapgetfreeinfo.c: New files.

score/src/objectinitializeinformation.c: Remove warning.
* libc/Makefile.am: Added mallocfreespace.c.
* libc/mallocfreespace.c: New file based on work by Nick Simon
<Nick.SIMON@syntegra.bt.co.uk> which he included in malloc.c.
* libc/libcsupport.h: Added prototype for malloc_free_space().
