This patch is not in the upstream pjproject and does unsafe things with
the timer->_timer_id and timer->_grp_lock values in pj_timer_entry_reset()
outside of the timer heap lock.  pj_timer_entry_reset() is also called for
timers that are not about to be rescheduled in a few places.

This allows us to process AO2 statistics for total objects, memory
usage, memory overhead and lock usage.

* Install refstats.py and reflocks.py into the Asterisk scripts folder.
* Enable support for reflocks.py without DEBUG_THREADS.

Steal a bit from the ao2 magic to flag when an object lock is used.
Remove 'lockobj' from reflocks.py since we can now record 'used' or
'unused' for those objects.

Add comments to explain thread safety of the 'struct __priv_data'
bitfields.

This patch sets the callerid_tag to empty string by default.

If the callerid_tag is set to NULL then the tag does not
become part of a connected line update.
For example:
Alice's tag is "Alice".
Bob's tag is empty.
Charlie's tag is "Charlie".
Alice calls Bob and then does attended transfer to Charlie.
When Alice hangs up the CONNECTEDLINE(tag) is "Alice"
on the interception routine on the Charlie's channel, but should be empty.

Ths patch also fix memory leaks if there are more then one options
"callerid", "callerid_tag", "voicemail_extension" and "contact_user"
in the pjsip.conf endpoint definition.

thread_worker_pair, set_size_data and task_pushed_data structures are
allocated with AO2 objects, passed to a taskprocessor, then released.
They never have multiple owners or use locking so AO2 only adds
overhead.

The field used to store call arguments was not large enough to hold the
arguments string that can be constructed for 'open'.  Expand it to
prevent this warning/error.

The return status when there was no change in statsd.conf was incorrect.
This resulted in the wrong status message on the CLI when reloading the
module.

* Fixed cleanup on initial load if initializing statsd failed.

ast_sendtext_data() would create an incorrect T.140 text frame which
length include the null terminator byte. It causes ultimately RTP
packets to be send with this trailing 0. The proposed fix just set the
correct length to the text frame

This has no effect on startup since AST_MODULE_LOAD_FAILURE aborts
startup, but it's possible for this code to be returned on manual load
of a module after startup.

It is an error for a module to not have a load callback but this is not
a fatal system error.  In this case flag the module as declined, return
AST_MODULE_LOAD_FAILURE only if a required module is broken.

Expand doxygen documentation for AST_MODULE_LOAD_*.

* Make load_module() cleanup if it failed to setup the module.

* Make unload_module() always return 0.  It is silly to fail unloading if
the hook function we try to unregister was not even registered.

If codec_speex fails to register a translator it would cause Asterisk to
exit instead of continue as a DECLINED module.

* Make unload_module() always return 0.  It is silly to fail unloading if
any translators we try to unregister were not even registered.

Fix redirection to /dev/null of cleanup commands.  The '2' was being
interpreted as part of the command instead of part of the redirect.

I think this module is so screwed up that it doesn't work anymore.  Even
with these attempts to fix things it still won't gracefully shut down.
The module refs will not go to zero to allow unloading the module.

* Fix module ref counting dealing with the SMDI interface object.  There
were several off-nominal paths that unbalanced the module ref count.  Also
the destructor freed the ao2 object itself which is bad.  Made the
smdi_read thread not hold its own ref to the SMDI interface object so when
all refs go away the destructor will stop the listener thread.

* Fixed the smdi_load() return code of 1 concerning the number of
listeners.  The test was inverted.

This module is an optional dependency of a couple of other modules.  If it
declines to load, it then forces other modules that can optionally use
this module to also decline.

* Made use the default configuration if the config file does not exist and
simplified some of the logic.
