ssfmalloc: Take advantage of CHERI bounds-checking.
* lib/ssfmalloc.h: Include <cheri.h>.
(struct dissected_page_header) [CHERI]: Add field 'whole_page'.
(init_small_block_page, init_medium_block_page) [CHERI]: Initialize it.
(free_block_from_pool) [CHERI]: Use this field to initialize
pool->freeable_page.
(allocate_block) [CHERI]: Return a pointer with a tight upper bound.
