More headers removal and sorted the remaining alphabetically.

Most noticeable that were removed are sys/types.h which will be included from
stdlib.h and in turn also brings along sys/cdefs.h. The other one is limits.h
that was used with the old idiom (denom * random() / LONG_MAX), although it was
only removed were applicable (some files still need that header).
