libpager: Use libc heap for pagemap
libc already implements the functionality for allocating and managing
memory blocks like the pagemap. Using libc functions gives us some
additional niceties like overflow checking in reallocarray (). it also
means that we will not allocate a whole page of memory if we need to
store just a few integers.
