Review request for Asterisk Developers.


Changes
-------

Lock the pvt, the chan, and the bridged chan with fancy deadlock avoidance.  Please pay special attention to the deadlock avoidance code when reviewing.


Summary
-------

This patch enables asterisk to send T.38 faxes over local channels.  To accomplish this, support for ast_channel_queryoption() was added to chan_local and support for passing AST_CONTROL_T38_PARAMETERS control frames through a generic bridge was added.


Diffs (updated)

Testing
-------

I passed several T.38 faxes over a local channel bridged to a sip channel.


Thanks,

Matthew
