This was ok tb@ but never commited.


Remove uneeded includes, and sort those that can be sorted (some can't):

Committed (mostly). Thanks!

I left stdlib.h and unistd.h because I think that C99 requires that
those be included when using libc, although failing to do so is
non-fatal. You'll see warnings for this if you use a newer compiler and
build with -Wall.
