It is possible for there to be multiple encryption init info structure.
For example, to support multiple key systems or in key rotation. This
changes the AVEncryptionInitInfo struct to be a linked list so there
can be multiple structs without breaking ABI.

Some of these enums have gaps in between their values, since they correspond
to the values in various specs, instead of being an incrementing list.
Fixes segfaults when, for example, using the valid API call:
av_color_primaries_from_name("jecdec-p22");

This uses any devices it can find on the host system - on a system with no
hardware device support or in builds with no support included it will do
nothing and pass.
Every fourcc in vaapi_drm_format_map should be in
vaapi_format_map, so add an assert to ensure we have the right maps.
