Add also auto-start on local camera at any video capable call.
Fix VideoGenerator class.

Note: bliting function works only with YUV420 planar pixel format.

- fix also some Copyright dates.

Thanks to the new custom_io flag in libavformat's SDP demuxer, we can manage
our own UDP transports for RTP and RTCP. This allows us to comply with
RFC 4961.

If an older version of libavformat is detected, we fallback to sending and
receiving on different sockets.

This way VideoSendThread will be able to implement it and we avoid the
callback hackery we had before.

Decompose big run() method into getFrame (which may be either from camera
or RTP) and renderFrame.

The SDP is already in memory and can be used as such by simply
overriding the "read" function of our AVIOContext.

Also, even if tryEnterMutex returns false, we must call leaveMutex.
This was leading to a dead lock when hanging up and answering a call at
the same time.

- Don't deadlock when requesting fast picture update
- Video thread should not modify it's "running flag"
- The "running" flag is now an atomic variable

This way we can cleanly stop video threads, even if they are in error
states.

Got rid of intermediate buffer

Does not compile!!!

We need GTK3 to use the recent, non-broken clutter-gtk-1.0
Completely drop GTK2 compatibility

TODO: - help dialog
      - migrate to GSettings instead of gconf (not mandatory)
      - fix runtime warnings about the dynamic toolbar (hangup buttons etc)

Fallback on cairo for video display if clutter doesn't work
Use the same rgb format for clutter and cairo renderers (BGRA)
Fix a flaw in design (client needed to tell the daemon which format it needed)
