23329d07cf func_periodic_hook: add module ref counting
This module lacked necessary module ref count incrementing and decrementing
when used.  This patch adds it.  There's already a datastore used, so doing the
ref counting along with the lifetime of the datastore provides a convenient
place to do it.

607c6e9772 func_periodic_hook: List more modules as dependencies
This module makes use of some existing Asterisk components.  app_chanspy was
already listed as a dependency.  There are a few function modules used, as
well, so list them.

ea290b2c3e func_periodic_hook: New function for periodic hooks.
This commit introduces a new dialplan function, PERIODIC_HOOK().
It allows you run to a dialplan hook on a channel periodically.  The
original use case that inspired this was the ability to play a beep
periodically into a call being recorded.  The implementation is much
more generic though and could be used for many other things.

The implementation makes heavy use of existing Asterisk components.
It uses a combination of Local channels and ChanSpy() to run some
custom dialplan and inject any audio it generates into an active call.

The other important bit of the implementation is how it figures out
when to trigger the beep playback.  This implementation uses the
audiohook API, even though it's not actually touching the audio in any
way.  It's a convenient way to get a callback and check if it's time
to kick off another beep.  It would be nice if this was timer event
based instead of polling based, but unfortunately I don't see a way to
do it that won't interfere with other things.
