Do not pass null for free, memcpy and memmove

Browse source 
* lib/jit_memory.c: Do not call free on NULL pointers.

	* include/lightning/jit_private.h, lib/jit_note.c,
	lib/lightning.c: Add a wrapper to memcpy and memmove
	to not actually call those functions with a zero size
	argument, and likely also a null src or dst.
