98acb3260d rist: Add combined bonding-method support
This patchs add support for configuring the bonding method used. There is
two method specified

 - redundant: All the RTP packets are replicated
 - combined: RTP packet are evenly distributed over each links

Additionally, an application can set the "dispatcher" property in order
to implement custom dispatching method. Whenever the "dispatcher"
property is set, "bonding-method" property will be ignored.

9a443c04bc ristsrc: Implement per session stats
As we can now have multiple sessions, stats need to be implemented per
session. This follow RTPSession model with sources. The stats are now:

    dropped: 0
    received: 0
    recovered: 0
    permanently-lost: 0
    duplicates: 0
    retransmission-requests-sent: 0
    rtx-roundtrip-time: 0
    session-stats:
        session-id=0
            rtp-from=""
            rtcp-from=""
            dropped=0
            received=0
        session-id=1
            rtp-from=""
            rtcp-from=""
            dropped=0
            received=0
        . . .

session-stats is a GValueArray as there is no better alternatives.

f0d04b39dd rist: Add a plugin implenting RIST TR-06-1 Simple Profile
RIST TR-06-1 is a specification for video streaming made by the VSF
group. It is using a subset of RTP specification to which some
modification has been made to improve RTX behaviour and avoid any need
for signaling. The plugin implement ristrtxsend / ristrtxreceive element
which are the RIST specific equivalent of rtprtxsend/rtprtxreceive and
ristsink / ristsrc which implement rist transmitter and receiver. The
RIST protocol is meant to be used in unidirectional way. Typically, MPEG
TS over RTP is used.

Currently we support unicast and multicast streaming according to the
specification. This patch does not include any bonding support yet. The
ristsrc element introduce rist:// URI handling in parallel to it's
property configuration interface.
