Matthew Waters 427c3f4442 rtp: add base object for reading/writing rtp header extensions (RFC5285)
Facilitates the creation of rtp header extension implementations that
can be reused across applications.

Implementations are registered into the GStreamer registry as elements
(idea from GstRTSPExtension) and can be retrieved by URI or filtered
manually.  RTP header extensions must have the classification
"Network/Extension/RTPHeader" to be considered as a RTP Header
extension.
