Review request for Asterisk Developers.


Changes
-------

Added and updated comments to try to make it clearer.


Bugs: ASTERISK-24649
    https://issues.asterisk.org/jira/browse/ASTERISK-24649


Repository: Asterisk


Description
-------

When code imparts a channel into a bridge to swap with another channel, a ref needs to be held on the swap channel to ensure that it cannot dissapear before finding it in the bridge.

* The ast_bridge_join() swap channel parameter now always steals a ref for the swap channel.  This is the only change to the bridge framework's public API semantics.

* bridge_channel_internal_join() now requires the bridge_channel->swap channel to pass in a ref.

Testing

Thanks,
