Commit Message

Lynne Nov. 18, 2021, 5:46 a.m. UTC
This commit moves the common Vulkan framework into libavutil,
allowing it to be used in libavcodec. Each library that uses it is
expected to #include the .c/.h files into their own templates,
that may include extra library-specific functions, and compile an
object file to locally provide the necessary Vulkan code.
This also decouples the libglslang dependency from the framework,
eliminating the libglslang dependency on vf_libplacebo.

The libavcodec hwaccel I'm writing depends on this.
Patch attached.
