Minor optimization nit.

    Rather than calling the accessor funcition three times and potentially retrieving different values.  Save it to a local variable and then test.
    flags = ast_channel_softhangup_internal_flag(chan);
    return flags == asyncgoto || flags == unbridge || flags == (both)

As it consumes voice frames, the initial bridge type is a simple bridge. The framehook is removed when both channels are in the bridge; however, this does not currently cause the bridging framework to re-evaluate the bridge. This patch adds a AST_SOFTHANGUP_UNBRIDGE poke to the transfer target channel when a framehook is removed so the bridge can re-evaluate itself.

Sending a re-INVITE to a channel that is about to be hung up is not nice - in fact, there's a good chance we'll send the BYE request before the channel has had a chance to send back a 200 OK. To be somewhat nicer, this patch makes it so that we only send the re-INVITE if there's a chance the channel will survive the native bridging experience.
