08d0a8992d hwcontext_vulkan: minor corrections for DMABUF mapping 
We need to consider the amount of layers instead of the image's planes.

a88449ffb2 lavu: add Vulkan hwcontext code 
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.
