[vlc-devel] [PATCH] [RFC] decoder: add more decoder device types

These are types needed to move the decoder pools that exist in various display
modules closer to the decoder.

That means we need to make the decision early on which flavor of OpenGL will be
used before the OpenGL display module is created. Depending on the platform
used it could be VAAPI, VDPAU, DXVA2, OpenGL PBO (persistent and non-persistent).

And to do that we need to create the "decoder device" using the es_format_t
that will be decoded (so we can pick a hardware decoder or a software one),
which contains the codec, profile and dimensions. When any of these change we
will need to create a new decoder device (or check the one we have is
