Merge r183572, r173649, r183650, r183690, and r183764 from head to
stable/7:

  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.

  Use soconnect2() rather than directly invoking uipc_connect2() to
  interconnect two UNIX domain sockets.

  Now that portalfs doesn't directly invoke uipc_connect2(), make it a
  static symbol.

  Remove stale comment (and XXX saying so) about why we zero the file
  descriptor pointer in unp_freerights: we can no longer recurse into
  unp_gc due to unp_gc being invoked in a deferred way, but it's still
  a good idea.

  Remove stale comment: while uipc_connect2() was, until recently, not
  static so it could be used by fifofs (actually portalfs), it is now
  static.
