Summary:                    [patch] T38 gateway
Description: 
Hi all,

I'm sending you patch containing new application app_faxgateway.c
("FaxGateway") which is able to mediate T30 to T38 and vice versa.
Feature is using spands library (I used spandsp-0.0.4pre18 and
spandsp-0.0.5pre4).

Best regards
Daniel.

---------------------------------------------------------------------- 
ive been striping the bits apart and making them more friendly to * and
res_fax

to allow the "Gateway" to manage the T38 parameter's within res_fax i
propose a callback
to be placed in the bridge config.

a further callback needs to be added for the actual gateway when the
channel states are correct ast_generic_bridge must end and the
gateway start.

"t38_gateway_handle_parameters" res_fax will register this and if FAXOPTS
and friends enable T38 Gateway on the call via a option this call back will
return a result indicating handled / not handled / T38 Gateway Start.

if it is not handled either due to non existence or if not handled status
quo is maintained.

on T38 Gateway start the audio loop must end and the T38 gateway bridge
callback must be called this is in res_fax and calls 
technology IE res_fax_spandsp.

this callback will need to go into ast_generic_bridge and replace the
current AST_CONTROL_T38_PARAMETERS case.

Please let me know if this method is in line with the API requirements.
