This is a non-POSIX/ISO-C header. It is ok to include this on Linux, but it is obsolete on BSD; FreeBSD even throws an error if you include it with __STDC__ defined. Every system should nowadays have malloc() defined in stdlib.h. Diff is largely mechanical, replacing malloc.h with stdlib.h where it is not yet included anyway.
