* libcsupport/src/mallocfreespace.c, rtems/Makefile.am,
rtems/include/rtems/rtems/region.h, score/Makefile.am,
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/include/rtems/score/object.h,
score/src/objectinitializeinformation.c: Remove warning.
