Patch against gst-plugins-bad Git master, as of approx. May 5th 2011 at 22:00

It seems that new Apple devices expect a slightly different protocol when
receiving an AirTunes stream. I have written a patch that allow apexsink to
stream to these devices. To support this, the plugin now has two additional
properties: generation and transport-protocol.

With this patch, I am able to stream to AirServer, a software implementation of
the newer protocol. There are some issues remaining, probably having to do with
the use of usleep (notice the comment in the patch):

1. For some reason, no audio plays unless I specify "--gst-debug=apexsink:5" on
the gst-launch command line. Very odd. Perhaps printing to the console slows
down the timing of things.

2. I hear a skip every 6-40 seconds.
