Patch adding property to disable GET_PARAMETER/OPTIONS based keep alive.

The rtspsrc sends keep alive messages periodically either by sending
GET_PARAMETER or OPTIONS, preferred in that order.

We've found that a specific IP camera (Arecont AV8635:
http://www.arecontvision.com/index.php?section=product&subsection=product_details&product_id=46)
prefers to receive keep alive via periodic RTCP.  This works fine as rtspsrc
sends these.

However, we've found that this camera actually stops sending data when it
receives OPTIONS sent as keep alive.  We've had to patch gstreamer to disable
the GET_PARAMETER/OPTIONS keep alive when communicating with this camera.

Submitting patch for inclusion into rtspsrc, if it is generally useful.
