c0a2098a2d emu: make grub_free(NULL) safe
The grub_free() implementation in kern/mm.c safely handles NULL
pointers, and code at many places depends on this.  We don't know that
the same is true on all host OSes, so we need to handle the same
behavior in grub-emu's implementation.

f80ca28e20 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.

ed7fbf43c2 * grub-core/kern/emu/mm.c (grub_memalign): Don't define if there is no
implementation available to cause compile-time rather than runtime
	error.
