The check_x86asm() checks would force enable these variables on success, bypassing any --disable-* command line option. This is important in the case of AVX512, where the relevant define is used to choose between different values for memory alignment and strides in some allocations.

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.

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.

This commit adds the necessary code to initialize and use a Vulkan device within the hwcontext libavutil framework. Currently direct mapping to VAAPI and DRM frames is functional, and transfers to CUDA and native frames are supported. Lets hope the future Vulkan video decode extension fits well within this framework.

We are beginning to consider scenarios where a given HW Context may be able to transfer frames to another HW Context without passing via system memory - this would usually be when two contexts represent different APIs on the same device (eg: Vulkan and CUDA). This is modelled as a transfer, as we have today, but where both the src and the dst are hardware frames with hw contexts. We need to be careful to ensure the contexts are compatible - particularly, we cannot do transfers where one of the frames has been mapped via a derived frames context - we can only do transfers for frames that were directly allocated by the specified context. Additionally, as we have two hardware contexts, the transfer function could be implemented by either (or indeed both). To handle this uncertainty, we explicitly look for ENOSYS as an indicator to try the transfer in the other direction before giving up.
