* score/include/rtems/score/protectedheap.h,
score/src/pheapallocate.c: Changed base implementation of protected
heap allocations to use _Heap_Allocate_aligned_with_boundary().
* libcsupport/include/rtems/malloc.h, libcsupport/src/rtems_malloc.c:
Check system state. Process deferred frees. Renamed rtems_malloc() in
rtems_heap_allocate_aligned_with_boundary().
* score/src/pheapallocatealigned.c: Removed file.
* score/Makefile.am: Update for removed file.
