a2db7343e0 lavfi: add an avgblur_vulkan filter 
This commit adds a fast avgblur Vulkan filter.
This will reset Intel GPUs on Linux due to a known, two-year-old driver bug
(!834 on mesa's gitlab).

6fca61bbc9 lavfi: add Vulkan filtering framework 
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.

88d2ccbe93 lavfi/vf_hwupload: Add support for HW -> HW transfers 
As we find ourselves wanting a way to transfer frames between
HW devices (or more realistically, between APIs on the same device),
it's desirable to have a way to describe the relationship. While
we could imagine introducing a `hwtransfer` filter, there is
almost no difference from `hwupload`. The main new feature we need
is a way to specify the target device. Having a single device
for the filter chain is obviously insufficient if we're dealing
with two devices.

So let's add a way to specify the upload target device, and if none
is specified, continue with the existing behaviour.

We must also correctly preserve the sw_format on such a transfer.

c044ac2071 avfilter/vf_geq: use per-thread AVExpr for expression evaluation 
There was no consensus about separating AVExprState from AVExpr so here is a
minimal patch using the existing AVExpr to fix ticket #7528.

ab39f0d841 avfilter/asrc_sinc: Don't allocate arrays separately 
Besides the obvious advantages this also fixes a potential memleak:
If only one of the arrays had been successfully allocated, the other
would leak. This also fixes Coverity issues #1440386 and #1440387.
