calloc: Make sure we always have an overflow-checking calloc() available
...
This tries to make sure that everywhere in this source tree, we always have
an appropriate version of calloc() (i.e. grub_calloc(), xcalloc(), etc.)
available, and that they all safely check for overflow and return NULL when
it would occur.

* grub-core/kern/mm.c (grub_real_malloc): Decrease cut-off of moving the

pointer to 32K. This is the size of cache element which is the most
common allocation >1K. This way the pointer is always around blocks
of 32K and so we keep performance while decreasing fragmentation.
