malloc/memalign: Return NULL if the request is too large
It's what this function family is defined to do, we currently don't usually run into the case (see: not too many die() instances going around), it's more useful to try to recover, and the JPEG parser can run into it if the work buffer size exceeds the remaining heap, whereas its sole user (the bootsplash code) knows what to do when seeing a NULL. Use xmalloc() if you want an allocation that either works or dies. tl;dr: That code path isn't usually taken. Right now it crashes. With this patch it _might_ survive. There is a use-case for doing it like that now.
