mallinfo is meant to be API compatible with Linux, where it's provided by malloc.h. Make stdlib.h include malloc.h for now. It can be removed once all users are updated to include malloc.h instead of stdlib.h. I have some app code which uses mallinfo(). I want to share it between platforms. This commit allows me to reduce platform-ifdefs. (I think the API actually originated with System V. I don't remember how it was there though. Anyway, I guess the compatibility with Linux is more important than System V these days.)
