    Modify bridging to properly evaluate DTMF after first warning is played
    
    The main problem is currently if the Dial flag L is used with a warning sound,
    DTMF is not evaluated after the first warning sound. To fix this, a flag has 
    been added in ast_generic_bridge for playing the warning which ensures that if
    a scheduled warning is missed, multiple warrnings are not played back (due to a
    feature evaluation or waiting for digits). ast_channel_bridge was modified to
    store the nexteventts in the ast_bridge_config structure as that information
    was lost every time ast_channel_bridge was reentered, causing a hangup due to
    incorrect time calculations.
