ive made some cleanups and moved it into res_fax res_fax_spandsp this is the framework and not production code
unfortunately i have no means of testing it at the moment and require help.
i have cleaned the code up substantially it is related to R459
hope this is found useful and aids in the goal to get it in 1.10.
Adds application FaxGateway / FaxDetect
Adds alternate bridge to Dial with new option.</pre>
