"REALLOC" is a word that reallocates memory using mremap of address a
of size m to be size n bytes and returns the lowest address of the
allocated block.

Note that this makes new page allocations for the process from the
kernel, and the granularity is in pages, i.e. a multiple of 4 kb.

The memory is reampped using the MREMAP_MAYMOVE flag,
