This patch is an optimization. Now that we monitor for any .conf file
changes (as soon as the event loop starts) we can skip automatic reload
of all .conf files and services if no .conf file has changed. Unless
the user issues an `initctl reload`, `init q`, or sends us SIGHUP.

Until now Finit has used mtime to determine if a file has been changed,
or simply touched to request reload, when `initctl reload` is called.
Using mtime for this purpose is a monumentally bad idea since time can
be changed at any point: a user may adjust the time, NTP continously
tunes the clock, and time stamps are stored as the walltime. So if we
compare timestamps against the last time we (booted or) did reload, we
would miss .conf file changes.
This patch replaces the mtime mistake with an inotify watcher for the
following files: /etc/finit.d/*.conf, /etc/finit.d/available/*.conf,
and /etc/finit.conf. All file changes between (bootstraps and) calls
to `initctl reload` are tracked, like the mtime backend it replaces.

This patch adds a 'once' counter to the svc_t for run/task jobs. This
counter is incremented when Finit calls service_start() and is reset on
runlevel changes.
Also, at the end of a runlevel each run/task have their state reset to
SVC_HALTED_STATE so they can be launched again for the new runlevel, if
so declared.

In commit eec32e2 support for reloading TTY configurations was added.
This patch is a follow-up to that with support for cleaning up and
removing allocated TTYs.
