commit b4f7aae67e1ab3be8f01c27190316683fbe9f0d8
from: Alexander Barton <alex@barton.de>
date: Sun Mar 25 19:59:01 2018 UTC

Correctly retry outgoing conenctions when forking a resolver failed

When ngIRCd failed to spawn a new resolver subprocess, the connection
structure was still marked as "SERVER_WAIT", and no new attempt to
connect to this server was made.

Thanks to Robert Obermeier for reporting this bug!

Closes #243.
