"sync" should be FALSE on udpsink for live streams

RTP packets should be sent as soon as they're available in case of a live stream. For playback, "sync" should be TRUE (the default) so that the stream is sent with proper timing over the network. See http://lists.freedesktop.org/archives/gstreamer-devel/2011-November/033911.html for a concrete example.
This not correct, sync should be set to TRUE in all cases. If it causes timing problems, the problem is in the element generating the timestamps.
