When a user sends a signal SIGHUP, we parse the configs again
traditionally on Unix.
We already use this for log-configs.
This signal allows apps to get notification and reload their
own configs.
For service applications that bind to networks (currently
only indexer) this allows users to pass the address:
0.0.0.0
to bind to. The effect will be that we find all the network
interfaces in the system and bind to all of them.
Notice that we already had "localhost" as an alias to bind to both
v4 and v6 loopback interfaces.
This new feature depends on optional dependency QtNetwork.
All client apps (=connecting to a server only) now gained the verbose
and quiet command line arguments to select a different level of
verbosity.
Servers don't need this as they use a config file.
This also makes the --debug option only for debug builds as the logging
system already doesn't compile in debug statements otherwise, it makes
little sense to try to print them.
Now everyone auto-connects to localhost unless passed the
option --connect=
Also make indexer find the logs.conf from the same dir as the
commandline passed config file.
This makes running it as a service more useful.
