Richard Mudgett 11b3c3add1 Crash while transferring a call during DTMF feature timeout. ...

When a call is being attended transferred during the time between
AST_FRAME_DTMF_BEGIN and AST_FRAME_DTMF_END, the transferred channel
becomes a zombie (so tech data is not available), making ast_dtmf_stream()
segfault when it tries to send the DTMF digit (at least with SIP
channels).

Patch based on feature-end-zombie.patch uploaded by Irontec (license 1256)

* Check for zombies when ast_channel_bridge() returns.

* Guarantee that the fo parameter value is initialized in
ast_channel_bridge() before any returns.

(closes issue #19116)
