This caused a bug when a SOA query answer was received before
reloading was complete, so the zone wasn't visible in the zone
database yet.

This prevents mixing up the current IXFR and started AXFR.

This was used before for knotc and zcompile, so the only problem is
when sources are configured and not installed, restart would expect
binary to be at $(sbindir)/knotd.

AF_UNIX is now preferred over AF_INET sockets, although it is still
off by default.
When TCP/IP is used, default port changed from 5553->5533 (free).
AF_UNIX socket based control doesn't use (naturally) 'allow' section.

It is still possible to control knotd using signals though,
but the 'knotc' will use just the one configured channel not a mix
of signals and channel.

Removed 'pidfile' config option in favour of 'rundir' for later
storage of UNIX sockets and other stuff.
