void *	onion_low_malloc (size_t sz)
	NEVER FAILING MEMORY ALLOCATORS.
void *	onion_low_scalar_malloc (size_t sz)
	Our malloc wrapper for scalar data which does not contain any pointers inside.Knowing that a given zone does not contain any pointer can be useful, e.g. to Hans Boehm's conservative garbage collector on http://hboehm.info/gc/ using GC_MALLOC_ATOMIC....

	POSSIBLY FAILING MEMORY ALLOCATORS.
void *	onion_low_try_scalar_malloc (size_t sz)
	Our malloc wrapper for scalar data which does not contain any pointers inside. May return NULL on fail.
