From: Haihao Xiang <haihao.xiang at intel.com>

The oneAPI Video Processing Library (oneVPL) is a single interface for
encode, decode and video processing[1][2]. oneVPL is a successor to Intel(R) Media
SDK, but removed obsolete features. Intel(R) Media SDK lifetime comes to an
end now, new features for new Intel Gen platforms will be supported in oneVPL
only[3].

It is recommended to use oneVPL for new work, even for currently available
hardwares[4]. Hence, this patchset added a new option --enable-onevpl to bring
the support for oneVPL in QSV, new features for oneVPL will be implemented in
other patchset, for example, we are implementing av1_qsv encoder
(https://github.com/intel-media-ci/ffmpeg/pull/515).

option --enble-libmfx still works with Intel(R) Media SDK.

Note user can't enable onevpl and libmfx together.

oneVPL dispatcher:

oneVPL GPU runtime for new Intel Gen platforms:
https://github.com/oneapi-src/oneVPL-intel-gpu

v9:
  - Don't add new member in AVVAAPIDeviceContext, leave a TODO for multiple Intel GPUs support on Linux
    (This update doesn't affect Windows user, it also doesn't affect Linux user with single Intel GPU.
    We are adding new API to get device info from libva)
  - Rebased this patchset against the latest master and fixed lots of conflicts

Haihao Xiang (10):
  configure: ensure --enable-libmfx uses libmfx 1.x
  configure: fix the check for MFX_CODEC_VP9
  qsv: remove mfx/ prefix from mfx headers
  qsv: load user plugin for MFX_VERSION < 2.0
  qsv: build audio related code when MFX_VERSION < 2.0
  qsvenc: support multi-frame encode when MFX_VERSION < 2.0
  qsvenc: support MFX_RATECONTROL_LA_EXT when MFX_VERSION < 2.0
  qsv: support OPAQUE memory when MFX_VERSION < 2.0
  qsv: use a new method to create mfx session when using oneVPL
  configure: add --enable-libvpl option
