Summary:                    [new feature] support for T.38 pass-through
Description: 
Using already done work on behalf of
https://issues.asterisk.org/view.php?id=12380 and
https://issues.asterisk.org/view.php?id=15285, I'm going to
prepare T.38 pass-though support for chan_h323.
This includes:
1) T.38 capabilities negotiation (as done in chan_sip)
2) SIP<->H323 T.38 pass-through
3) support for RxFax(), TxFax() applications.

I have already a patch that works with hylafax + t38modem +
RxFax()/TxFax().
I need to make more tests before posting it here.

I will prepare patch(es) for 1.6.0.21 (we use it in production custom
system).
I can provide support in case if anyone interested has issues during
tests.
However I think I won't be able to provide patches for other Asterisk
versions due to lack of time. But it shouldn't be difficult to merge to
other Asterisk version for anyone interested because chan_h323 is not
heavily developed during recent years.

Please let me know if anybody is interested in testing/using/reviewing.

forgot to say, that I've also implemented a switch back to voice mode after
T.38 fax is transmitted.
