/* Attempt to install hooks in mmalloc/mrealloc/mfree for the heap specified
by MD, to detect memory corruption. Note that MD may be NULL to specify
the default heap that grows via sbrk.
Note that for freshly created regions, we must call mmcheckf prior to any
mallocs in the region. Otherwise, any region which was allocated prior to
installing the checking hooks, which is later reallocated or freed, will
fail the checks! The mmcheck function only allows initial hooks to be
installed before the first mmalloc. However, anytime after we have called
mmcheck the first time to install the checking hooks, we can call it again
to update the function pointer to the memory corruption handler.
Returns zero on failure, non-zero on success. */
