Remove task privileged mode

Browse Source 
Previously, the task privileged mode has been used only when the named
was starting up and loading the zones from the disk as the "first" thing
to do.  The privileged task was setup with quantum == 2, which made the
taskmgr/netmgr spin around the privileged queue processing two events at
the time.

The same effect can be achieved by setting the quantum to UINT_MAX (e.g.
practically unlimited) for the loadzone task, hence the privileged task
mode was removed in favor of just processing all the events on the
loadzone task in a single task_run().
