Check that collectpads exists before removing pad
...
The core now calls release pad from finalize, at which point
the collectpads might have already been freed.

videomixer2: Add videomixer2 element
...
This is based on collectpads2 and is synchronizing
all streams based on the running time.
New features compared to old videomixer:
* Synchronizing frames on the running time
* Improved and simplified negotiation
* Full QoS support
* Variable framerate support
Fixes bug #626048 , #624905 .

in videomixer and it's also faster now when using SSE.

videomixer: if we're not linked downstream, we can do any format

Stupid me, assuming _get_allowed_caps() would actually return the
pad templates if there was no peer.

videomixer: Don't return caps in get_caps() that will be rejected
...
This commit basically puts _get_caps() in sync with accept_caps().
If we don't have a master pad OR the master pad caps aren't negotiated
then we just return the downstream allowed caps.
If we have a master pad with negotiated caps, we return those caps
with a free range of width/height/framerate

output buffers, intepollate timestamps and durations from the last seen ones.

videomixer: Implement basic QoS
...
This drops frames if they're too late anyway before blending and all
that starts but QoS events are not forwarded upstream. In the future
the QoS events should be transformed somehow and forwarded upstream.
