Russell Bryant 765b275976 Use poll() instead of select() in res_timing_pthread to avoid stack corruption.
This code did not properly check FD_SETSIZE to ensure that it did not try to
select() on fds that were too large.  Switching to poll() removes the limitation
on the maximum fd value.

David Vossel d532cbcd8a module load priority
This patch adds the option to give a module a load priority. The value represents the order in which a module's load() function is initialized.  The lower the value, the higher the priority.  The value is only checked if the AST_MODFLAG_LOAD_ORDER flag is set.  If the AST_MODFLAG_LOAD_ORDER flag is not set, the value will never be read and the module will be given the lowest possible priority
on load.  Since some modules are reliant on a timing interface, the timing modules have been given a high load priorty.

Russell Bryant 1fab70a1c6 Resolve issues with choppy sound when using res_timing_pthread.
The situation that caused this problem was when continuous mode was being
turned on and off while a rate was set for a timing interface.  A very easy
way to replicate this bug was to do a Playback() from behind a Local channel.
In this scenario, a rate gets set on the channel for doing file playback.
At the same time, continuous mode gets turned on and off about every 20 ms
as frames get queued on to the PBX side channel from the other side of the
Local channel.

Essentially, this module treated continuous mode and a set rate as mutually
exclusive states for the timer to be in.  When I dug deep enough, I observed
the following pattern:

   1) Set timer to tick every 20 ms.
   2) Wait almost 20 ms ...
   3) Continuous mode gets turned on for a queued up frame
   4) Continuous mode gets turned off
   5) The timer goes back to its tick per 20 ms. state but starts counting
      at 0 ms.
   6) Goto step 2.

Sometimes, res_timing_pthread would make it 20 ms and produce a timer tick,
but not most of the time.  This is what produced the choppy sound (or sometimes
no sound at all).

Now, the module treats continuous mode and a set rate as completely independent
timer modes.  They can be enabled and disabled independently of each other and
things work as expected.

Russell Bryant c461d29b0b Update the timing API to have better support for multiple timing interfaces.
1) Add module use count handling so that timing modules can be unloaded.

2) Implement unload_module() functions for the timing interface modules.

3) Allow multiple timing modules to be loaded, and use the one with the
   highest priority value.

4) Report which timing module is being use in the "timing test" CLI command.

Sean Bright fd8caa1778 This is basically a complete rollback of r155401, as it was determined that
it would be best to maintain API compatibility.  Instead, this commit introduces
ao2_callback_data() which is functionally identical to ao2_callback() except
that it allows you to pass arbitrary data to the callback.

Mark Michelson 0e5367f7eb Merge the changes from the res_timing_timerfd branch.
This provides a new timing interface. In order to use it,
you must be running a Linux with a kernel version of
2.6.25 or newer and glibc 2.8 or newer.

This timing interface is a good alternative if a timing
source is necessary (e.g. for IAX trunking) but DAHDI is
otherwise unnecessary for the system.

For now, this commit contains the actual work done in the
res_timing_timerfd branch. There are no notices in the README
or CHANGES files yet, but they will be added in my next commit.

The timing API of Asterisk also needs to have a bit of work done
with regards to choosing which timing interface to use. This commit
makes the choice a build-time decision, by only allowing one of
the timer interfaces to be chosen in menuselect. It would be preferable
if the choice could be made at run-time, however. The preferred timing
interface could be loaded and tested, and if it does not work, choice
number two may be used instead. That sort of thing. That is beyond
the scope of work in this branch though.

Sean Bright 30d1744ffc Add ability to pass arbitrary data to the ao2_callback_fn (called from
ao2_callback and ao2_find).  Currently, passing OBJ_POINTER to either
of these mandates that the passed 'arg' is a hashable object, making
searching for an ao2 object based on outside criteria difficult.

After working on the ao2_containers branch, I noticed
something a bit strange. In all cases where we provide
a callback function to ao2_container_alloc, the callback
function would only return 0 or CMP_MATCH. After inspecting
the ao2_callback() code carefully, I found that if you're
only looking for one specific item, then you should return
CMP_MATCH | CMP_STOP. Otherwise, astobj2 will continue
traversing the current bucket until the end searching for
more matches.

In cases like chan_iax2 where in 1.4, all the peers are
shoved into a single bucket, this makes for potentially
terrible performance since the entire bucket will be
traversed even if the peer is one of the first ones come
across in the bucket.

All the changes I have made were for cases where the 
callback function defined was passed to ao2_container_alloc
so that calls to ao2_find could find a unique instance
of whatever object was being stored in the container.

Russell Bryant 9a301b9f20 Merge res_timing_pthread. This is a timing interface for Asterisk that
does not require DAHDI.  It's called "pthread" because it uses a pthread
API call in the timing thread for sleeping and ensuring we wake up at
an appropriate time.  I wasn't sure what else to call it.  :)

The timing API requires a file descriptor that can be polled on.  So,
when you open a timer, this module creates a pipe and returns the read
end of the pipe.  There is a background thread that wakes up every 10ms
and checks to see if any of the currently open timers need a 'tick' and
writes to the appropriate pipe.
