Add server support for signal channel (RFC 4254, 6.9)

[Jay Weisskopf]

Is there an OpenSSH project maintainer that can speak authoritatively on
this issue? What will it take to add support for section 6.9 of the RFC
(beyond the patch[es] in issue 1424)? Is there a flaw with this part of the
RFC that makes implementation problematic?

Thanks,
Jay
