Drop VPP support

This removes complete support for intel VPP. Huge thanks to @btbn who has programmed this intel api. Sadly enough, the intel drivers are not yet ready. Especially on haswell it runs really bad.

We will do it differently in the near future. By copyiing the Frame back to system memory. That costs us 1ms per Frame when done with SSE2. Here Bobbing is totally inexpensive and even a simple Celeron 847 can handle it without problems.

For the faster CPUs now yadif can be used. One of the best deinterlacers around.
