0568af521e lavfi/opencl: Avoid deprecation warnings when built with post-1.2 headers 
The intended target is OpenCL 1.2, so disable warnings for APIs deprecated
after that.  This primarily applies to clCreateCommandQueue(), we can't use
the replacement clCreateCommandQueueWithProperties() because it was
introduced in OpenCL 2.0.

Also remove some unnecessary includes from overlay and program filters so
that the define is available at the right moment.

2a1542d105 lavfi/opencl: Derive global work size from plane image sizes 
Add a new function to find the global work size given the output image and
the required block alignment, then use it in the overlay, program and unsharp
filters.  Fixes the overlay and unsharp filters applying the kernel to
locations outside the frame when subsampled planes are present.

2b2c8b22da libavfilter/vf_fps: Minor cleanups 
Since the config_props function now references both the input and output
links, rename the 'link' variable to 'outlink'.

Fix up some mismatching indentation.

Don't bother setting the width and height on the outlink; the filter

e4edc567a0 libavfilter/vf_fps: Rewrite using activate callback 
The old version of the filter had a problem where it would queue up
all of the duplicate frames required to fill a timestamp gap in a
single call to filter_frame. In problematic files - I've hit this in
webcam streams with large gaps due to network issues - this will queue
up a potentially huge number of frames. (I've seen it trigger the Linux
OOM-killer on particularly large pts gaps.)

This revised version of the filter using the activate callback will
generate at most 1 frame each time it is called.

This patch makes it possible to dinamically close the current segment
and step to the next one by introducing command handling capabilities
into the filter. This new feature is very usefull when working with
real-time sources or live streams as source. Combinig usage with zmqsend

c6bc18bc12 vf_hwupload/hwmap: Support setting a fixed pool size 
These filters do not directly know whether the API they are using will
support dynamic frame pools, so this is somewhat tricky.  If the user
sets extra_hw_frames, we assume that they are aware of the problem and
set a fixed size based on that.  If not, most cases use dynamic sizing
just like they did previously.  The hardware-reverse-mapping case for
hwmap previously had a large fixed size (64) here, primarily as a hack
for QSV use - this is removed and extra_hw_frames will need to be set
for QSV to work since it requires fixed-size pools (as the other cases
do, and which didn't work before).

2cbe6bac03 avfilter/vf_framerate: change blend factor precision 
This is done mainly in preparation for the SIMD patches.

- for the 8-bit input, decrease the blend factor precision to 7-bit.
- for the 16-bit input, increase the blend factor precision to 15-bit.
- make sure the blend functions are not called with 0 or maximum blending
  factors, because we don't want the signed factor integers to overflow.

Fate test changes are due to different rounding.

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

1c76134fe3 avfilter/drawbox+drawgrid - add option to prevent overwriting of source pixels 
If the user-supplied color in drawbox and drawgrid filters is non-opaque,
the box & grid painting overwrites the input's pixels (including alpha).
Users typically expect the alpha of the specified color to only act as a key
for compositing on top of the main input.

Added option allows users to select between replacement and composition.
Tested and documented.

b3cb9bd43f avfilter/drawbox: rename variable for maximum thickness 
The present value name for maximum thickness is 'max' which results in a
parse error of any thickness expression containing 'max(val1,val2)'.

Value renamed to 'fill'. Tested locally and documented.

3650cb2dfa lavu,lavfi,ffmpeg: Remove experimental OpenCL API 
This was added in early 2013 and abandoned several months later; as far as
I can tell, there are no external users.  Future OpenCL use will be via
hwcontext, which requires neither special OpenCL-only API nor global state
in libavutil.

All internal users are also deleted - this is just the unsharp filter
(replaced by unsharp_opencl, which is more flexible) and the deshake filter
(no replacement).
