Description
-------

This patch is a re-do of review 3535.

When review request 3535 was merged, a major problem with it was uncovered. UNBRIDGE soft hangup flags have a catastrophic effect on the pbx core if they leak out from the bridge layer: the channel gets hung up. With the number of threads involved in a blind transfer, and with the initial patch, it was likely that this would occur. This caused a large number of test failures

This patch is nearly identical with the one proposed in review 3535, save for the following changes:
 - We explicitly clear the UNBRIDGE flag when setting an after goto on a channel in a bridge
 - Defensively, if we encounter an UNBRIDGE flag in the pbx core, we handle it

Testing
-------

The blind transfer tests for PJSIP now pass (fingers crossed). See review 3586.


Thanks,
