Dynamically reconfigure pipeline in PLAY based on transports

This patch proposes a solution how to dynamically reconfigure pipeline in PLAY
based on transports.

The pipeline initially created in DESCRIBE does not contain specific transport
elements. The src pads on rtpbin are blocked so that no data can flow.
The receiver and the sender parts are added and configured after PLAY based on
the transports requested in SETUP.
If the media is shared, the streams are dynamically reconfigured after each
PLAY.
No queues are added to the pipeline unless there are multiple transports per
stream, case for shared medias.

We have tested the code and all unit tests pass except one, test_record in
rtspclientsink.c and we need your help on order to fix it.
