Review request for Asterisk Developers.


Changes
-------

Addressed feedback and pulled out other fixes into other commits.


Bugs: ASTERISK-24755
    https://issues.asterisk.org/jira/browse/ASTERISK-24755


Repository: Asterisk


Description (updated)
-------

A race condition happened between initiating a transfer and requesting
that a dialog termination be delayed.  Occasionally, the transferrer
channels would exit the bridge and hangup before the dialog termination
was requested.

* Made request dialog termination delay before initiating the transfer
action.  If the transfer fails then cancel the delayed dialog termination
request.
