[syslog-ng] [PATCH] lib/gprocess.c: Ignore SIGHUP inside the supervisor.

[Gergely Nagy]

Reloading syslog-ng's config is often done via a killall -HUP
syslog-ng command, which also sends a signal to the
supervisor. However, the supervisor did not handle said signal, thus
it exited as is the default for it.

To work around this issue, lets ignore SIGHUP inside the supervisor.
