Turn 'mainloop' into a subsystem.

We need a little refactoring for this to work, since the
initialization code for the periodic events assumes that libevent is
already initialized, which it can't be until it's configured.

This change, combined with the previous ones, lets other subsystems
declare their own periodic events, without mainloop.c having to know
about them.  Implements ticket 30293.
