5d56937e20 Workaround #6072: FFMPEG AAC encoding graded experimental 
Due to many reporing issues with different AAC encoder configurations
deactivate support by default. Can be enabled by compiling with
experimental codec support.

54c902b3b5 Optimize function xcrush_copy_bytes() 
Use memcpy to copy the bytes when we can assure that the memory areas does not overlap.
When the areas overlap, copy the area that doesn't overlap repeatly.
With this change, the copy is ~30x faster.

4df7200836 Cache the calculated color 
In desktop area, the next color has high odds to be the same of previous color.
If we cache the value, it can be reused by the next pixel avoiding recalculation.
This optimization can halve the function's processing.

5f0943f0fe primitives: add openCL support 
This patch adds the basic infrastructure to have openCL acceleration.
For now only YUV2RGB is implemented but other operations could be
implemented.
The primitives have been massively reworked so that we have an autodetect
mode that will pick the best implementation automatically by performing a
benchmark.

1112e2fffb codec: Set alpha channel to FF if not used (#5431) 
* Formatting

* codec: Set alpha channel to FF if not used

This PR initializes the alpha channel to FF. Before the alpha channel
contained uninitialized memory potentially causing problems when the
image data was used by an alpha channel aware frontend.
