[src/trunk]: src/sys * remove declarations of unp_bind, unp_discard, unp_disc...

[rtr <rtr%NetBSD.org@localhost>]

details:   https://anonhg.NetBSD.org/src/rev/16ec2552d941
branches:  trunk
changeset: 331105:16ec2552d941
user:      rtr <rtr%NetBSD.org@localhost>

description:
* remove declarations of unp_bind, unp_discard, unp_disconnect1, unp_drop,
  unp_shutdown1, unp_internalize and unp_output functions from sys/un.h
  and  instead declare them as static in uipc_usrreq.c with prototype
  declarations as necessary.

* remove struct lwp * parameter from unp_output() while here and just
  use curlwp instead.

as discussed with rmind
