Further minor cleanups to UNIX domain sockets:

- Staticize and locally prototype functions uipc_ctloutput(), unp_dispose(),
  unp_init(), and unp_externalize(), none of which have been required
  outside of uipc_usrreq.c since uipc_proto.c was removed.
- Remove stale prototype for uipc_usrreq(), which has not existed in the
  code since 1997
- Forward declare and staticize uipc_usrreqs structure in uipc_usrreq.c and
  not un.h.
- Comment on why uipc_connect2() is still non-static -- it is used directly
  by fifofs.
- Remove stale comments, tidy up whitespace.
