T.38 gw: V.17 call failing if far-end fails to train (FTT)

Hi!
When t38_gateway on sender side receives FTT, the subsequent TCF is sent to far-end as v17-14400-short-training not as v17-14400-long-training. Also we should switch to V.21 since as per Figure 5-2a/T.30, (TSI)DCS should be repeated as well.
Spandsp log and suggested fix is attached.

I just committed the a change, more or less as suggested. Its weird that didn't show up before. I'll have to put some more tests in the test scripts to test the fix more thoroughly, but its clearly a basically correct thing to do.
