- Use iwatch, modeled after pidfile plugin
- Use one .conf watcher for all *.conf paths/files
- Use full path of conf file for changes, from realpath().
This fixes a long-standing limitation on unique filenames
for services, that absolutely nobody knew about

Up until now Finit has only read /proc/cmdline to determine debug level,
single user mode, etc. This patch is one in a series to make enable it
to run also in containers.

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 extends the existing rlimit implementation to support setting
limits per service, run/task, inetd, and tty.
Use rlimit in /etc/finit.conf to change the global setting, which is
then inherited to each /etc/finit.d/*.conf. For each .conf file the
rlimit is reinitialized to the global finit.conf settings.
Also, add `unlimited` keyword, to replace the now deprecated `infinity`
keyword. The latter is however kept, for compatibility with previous
releases, for the foreseeable future.
