Fix queue crashes that would occur after the calling channel was
masqueraded.

The data passed to the end_bridge_callback was assumed to be data which
was
still stack'd. The problem was that with some call features, attended
transfers
in particular, a new bridge thread is started once the feature completes,
meaning
that when the end_bridge_callback is called, the end_bridge_callback_data
was
invalid.

To fix this problem, there are two measures taken

1. Instead of pointing to stacked data, we now used heap-allocated data
for
passing to the end_bridge_callback in app_queue
2. Since bridges can end multiple times on a single logical call, we wait
until
the final bridge is broken to actually set any queue variables. This is
accomplished
through reference-counting and the use of an
end_bridge_callback_data_fixup function
in app_queue.c
