3a754d51e0 FEC elements: document, remove irrelevant properties
The ulpfecenc "mux-seq" and "ssrc" properties were initially added
because the element did more than implement ULPFEC. As it was
decided that FLEXFEC would be implemented in a separate element,
both properties are now unneeded and confusing.

Change the default for the ulpfecenc multi-packet property,
as it is expected that most users of this element will be protecting video
streams.

Change the default property for the rtpredenc allow-no-red-blocks
property, as it should also be its default mode of operation.

d5ad50bd61 rtp: Implement ULPFEC (RFC 5109)
We expose a set of new elements:

* ULPFEC encoder / decoder
* A storage element, which should be placed before jitterbuffers,
  and is used to store packets in order to attempt reconstruction
  after the jitterbuffer has sent PacketLost events
* RED encoder / decoder (RFC 2198), these are necessary to
  use FEC in webrtc, as browsers will propose and expect ulpfec
  packets to be wrapped in red packets
