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.
The end goal here is to move the periodic callback to their
respective modules, so that mainloop.c doesn't have to include so
many other things.
This patch doesn't actually move any of the callbacks out of
mainloop.c yet.
This patch changes the slow process_t tests to use
run_main_loop_until_done() instead of do_main_loop() since
do_main_loop() initializes a lot of subsystem callbacks that we don't
need to run in our tests.

This is part of 28422, so we don't have to call
consider_hibernation() once per second when we're dormant.
This commit does not remove delayed shutdown from hibernate.c: it
uses it as a backup shutdown mechanism, in case the regular shutdown
timer mechanism fails for some reason.
The main.c code is responsible for initialization and shutdown;
the mainloop.c code is responsible for running the main loop of Tor.
Splitting the "generic event loop" part of mainloop.c from the
event-loop-specific part is not done as part of this patch.
