* libcsupport/Makefile.am, libcsupport/include/rtems/malloc.h,
libcsupport/src/malloc_walk.c, libcsupport/src/posix_memalign.c,
libcsupport/src/realloc.c, score/src/heapwalk.c: Add rtems_memalign
as helper and as exposed nmemalign variant with few restrictions.
Also turn on compilation of _Heap_Walk but make forced calls to it
conditionally compiled. This should allow more flexibility to the
user as to run-time checking of the heap.
* libcsupport/src/rtems_memalign.c: New file.
