Fix up headers

The additions to owl.h and some of the removals were done by
Alejandro Sedeño <asedeno@mit.edu> in commit
77a0258.

Notes:

* I think owl.c lost the need for sys/time.h when we punted select() in
  favor of glib's main loop.
* We don't actually need to include things like stdarg.h, stdio.h,
  glib/gstdio.h, glib-object.h.  I think they get indirectly included
  via owl.h and/or glib.h.  They're left in (or added in to) the files
  that use functions/types from them.
* I'm not entirely sure what sys/socket.h is doing in message.c.  It
  is there from the initial commit.  I suspect it might have had
  something to do with the call to getnameinfo.  message.c compiles
  without it, but
  http://pubs.opengroup.org/onlinepubs/009695399/functions/getnameinfo.html
  suggests that we're supposed to include it?  *shrugs*  I'm leaving it
  in, for now.  (Rather, I'll leave one copy of the #include in.)
