Compile warning fixes.

  Include header with prototypes for signals.c, and change prototypes and
definitions to match. This should not have any side effects as function
arguments are ignored.
  Ansify some functions with K&R definitions.
  printhex.c:fprintfhex() could be changed to a "sane" implementation, but
only change was "ansification".
