playbin3: Implement gapless playback
Similar in vein to the playbin2 architecture except that uridecodebin3 are prerolled much earlier and all streams of the same type are fed through a 'concat' element. This keeps the philosphy of having all elements connected as soon as possible. The 'about-to-finish' signal is emitted whenever one of the uridecodebin is about to finish, allowing the users to set the next uri/suburi. The notion of a group being active has changed. It now means that the uridecodebin3 has been activated, but doesn't mean it is the one currently being outputted by the sinks (i.e. curr_group and next_group). This is done via detecting GST_MESSAGE_STREAM_START emission by playsink and figuring out which group is really playing. When the current group changes, a new thread is started to deactivate the previous one and optionnaly fire 'about-to-finish'.
