- (djm) Sync bsd-* support files:

- deraadt@cvs.openbsd.org 2000/01/26 03:43:20
     [rresvport.c bindresvport.c]
     new bindresvport() semantics that itojun, shin, jean-luc and i have
     agreed on, which will be happy for the future. bindresvport_sa() for
     sockaddr *, too.  docs later..
   - deraadt@cvs.openbsd.org 2000/01/24 02:24:21
     [bindresvport.c]
     in bindresvport(), if sin is non-NULL, example sin->sin_family for
     the actual family being processed
