split the old algorithm (simple QoS analyser/av bitrate driver) and the  new algorithm (stateful QoS analyser/bandwidth bitrate driver)

add a network state and modify algorithm to handle simplest cases accordingly (eg. max quality in pure lossy network)

audio_stream_alive() now returns FALSE after timeout reached even if no RTP packet were received ever.

Replaced the concept of 'rendering filter capable of decoding'
by 'decoding filter capable of rendering'.
It's similar but allows to choose the decoder first (based on
video type) and then let it do the rendering if it can.

If the encoder filter takes too much time to encode,
v4l2 capture filter ends up using 100% cpu because
its internal list of available image is full.

So when this happens, a simple condition/signaling
pattern is used to allow the capture thread to wait
for an empty slot.

Always report video decoding errors. The interval between each sending of VFU requests is handled at a higher level.
