[malloc] Check integrity of free list
Check the integrity of the free memory block list before and after any
modifications to the list. We check that certain invariants are
preserved:
- the list is a well-formed doubly linked list
- all blocks are at least MIN_MEMBLOCK_SIZE
- no block extends beyond the end of our address space
- blocks remain sorted in ascending order of address
- no blocks are adjacent (i.e. any adjacent blocks have been merged)
