0c31a3876d avfilter/vf_framerate: simplify filter 
The framerate filter was quite convoluted with some filter_frame /
request_frame logic bugs. It seemed easier to rewrite the whole filter_frame /
request_frame part and also the frame interpolation ratio calculation part in
one step.

Notable changes:
- The filter now only stores 2 frames instead of 3
- filter_frame outputs all the frames it can to be able to handle consecutive
  filter_frame calls which previously caused early drops of buffered frames.
- because of this, request_frame is largely simplified and it only outputs
  frames on flush. Previously consecuitve request_frame calls could cause the
  filter to think it is in flush mode filling its buffer with the same frames
  causing a "ghost" effect on the output.
- PTS discontinuities are handled better
- frames with unknown PTS values are now dropped

Fixes ticket #4870.
Probably fixes ticket #5493.

This removes the XP compatibility code, and switches entirely to SWR
locks, which are available starting at Windows Vista.

This removes CRITICAL_SECTION use, which allows us to add
PTHREAD_MUTEX_INITIALIZER, which will be useful later.

Windows XP is hereby not a supported build target anymore. It was
decided in a project vote that this is OK.
