implement LoginGraceTime logging in listener

This removes the sigdie() in sshd.c and implements the LoginGraceTime
logging in the listener process. E.g.

Timeout before authentication for connection from [10.40.0.253]:2222 to
[172.30.30.4]:51846 (pid = 28473)

It also implements infrastructure for logging abnormal terminations
(e.g. the monitor exiting with SIGSEGV) and adds a framework for custom
handling of arbitrary monitor exit statuses that we can reuse to remove
the auth-pam.c sigdie() calls.

Oh, and it adds a SIGINFO handler to the listener for debugging :)
