playbin2/3: autoplug/caps: don't expand caps to ANY

Retrieving the pad template caps from a ghost pad returns ANY which when
merged with any other caps will return ANY.  ANY is not very specific
and may cause suboptimal code paths in e.g. decoders that assume the
lowest common denominator when presented with ANY caps.

Fixes negotiating dma-buf with vaapidecodebin between glupload in the
video sink element.

soup: Runtime compatibility support for libsoup2 and libsoup3

The src and sink elements no longer link against libsoup. It is now loaded at

For the unit-tests, we now build one version of the test unit file per libsoup
version found. So if both libsoup2 and libsoup3 are available on the host, the

... instead of index of DXGI adapter.

The order of IDXGIAdapter1 enumerated via IDXGIFactory1::EnumAdapters1
can be varying even there's no rebooting in case that GPU preference order
is updated by user (for example, it can be done by using NVIDIA Control Panel
in case of multi-GPU laptop system) and eGPU is another possible case.

So, for an element which requires fixed target GPU requirement,
index based device enumeration is unreliable.

d3d11: d3d11utils: Add support for DXGI Adapter LUID based D3D11 device context sharing

d3d11: d3d11device: Add gst_d3d11_device_new_{for_adapter_luid,wrapped}

* gst_d3d11_device_new_for_adapter_luid()
  Used for creating D3D11 device for a DXGI adapter (i.e., GPU)
  corresponding to a LUID (Locally Unique Identifier).
  This method can be useful for interop with other APIs such as
  Direct3D12, MediaFoundation, CUDA, etc.
* gst_d3d11_device_new_wrapped()
  Allows creating a new GstD3D11Device object by using already
  configured ID3D11Device. This is conceptually equivalent to
  gst_gl_context_new_wrapped()

playbin3: Avoid group deactivation deadlock.

Change locking around group deactivation to avoid deadlocks

Also properly protect group switching operations with

jpegdec: Support libjpeg-turbo colorspace conversion

The libjpeg-turbo has a built-in support for performing colorspace
conversion. The performance of this conversion is much better than
doing the same separately using videoconvert. Implement support for
this conversion to RGBx/xRGB/BGRx/xBGR formats. Other formats can
be easily added later.

- The decoding of various pixel formats can be tested and compared to
  non-libjpeg-turbo decoding as follows:
  for gfmt in {RGB,BGR}{,x} x{RGB,BGR} ; do
      echo "$gfmt"
      gst-launch-1.0 -q \
          videotestsrc pattern=colors ! \
          video/x-raw,format=${gfmt} ! \
          fakesink dump=true | \
  head -n 200 | tail -n 1
      gst-launch-1.0 -q --gst-plugin-path=build/ext/jpeg/ \
          videotestsrc pattern=colors ! \
          video/x-raw,format=${gfmt} ! \
  jpegenc ! \
  jpegdec ! \
  video/x-raw,format=${gfmt} ! \
  fakesink dump=true | \
  head -n 200 | tail -n 1

  Notice how the alpha channel is set to arbitrary value in case of the
  libjpeg-turbo decoding into RGBx/BGRx/xRGB/xBGR pixel formats. This is
  documented in libjpeg-turbo README.md as follows:
    "
    When using the RGBX, BGRX, XBGR, and XRGB colorspaces during decompression, the
    X byte is undefined, and in order to ensure the best performance, libjpeg-turbo
    can set that byte to whatever value it wishes.
    "

- The interlaced num_fields=2 mjpeg stream can be generated and
  tested as follows (this does require mjpegtools):

rtsp-media: Unprepare suspended medias too
