Even in this scenario, the frame still contains references to data that
won't be freed if the frame isn't unreferenced. And the AVFrame itself
will leak, too.

apply_palette() would free an AVFrame given to it only via an AVFrame *
(and not via AVFrame **) in three of its four exists (namely in the
normal path and in two error paths). So upon error the caller has no way
to know whether the frame has already been freed or not;
load_apply_palette(), the only caller, opted to free the frame in this
scenario.
This commit changes this by making apply_palette not freeing the frame
at all, which is left to load_apply_palette().

This commit adds a chromatic aberration filter for Vulkan that attempts to
emulate a lens chromatic aberration effect.
For a YUV frame it will instead shift the chroma channels, providing a
simple approximation.
This commit adds a Vulkan filtering infrastructure for libavfilter.
It attempts to abstract as much as possible of the Vulkan API from filters.
The way the hwcontext and the framework are designed permits for parallel,
non-CPU-blocking filtering throughout, with the exception of up/downloading
and mapping.
