videoio: HW decode/encode in FFMPEG backend; new properties with support in FFMPEG/GST/MSMF

* HW acceleration in FFMPEG backend

* fixes on Windows, remove D3D9

* HW acceleration in FFMPEG backend

* fixes on Windows, remove D3D9

* improve va test

* Copyright

* check LIBAVUTIL_BUILD >= AV_VERSION_INT(55, 78, 100) // FFMPEG 3.4+

* CAP_MSMF test on .mp4

* .mp4 in test

* improve va test

* check LIBAVUTIL_BUILD >= AV_VERSION_INT(55, 78, 100) // FFMPEG 3.4+

* CAP_MSMF test on .mp4

* .mp4 in test

* .avi for GStreamer test

* revert changes around seek()

* cv_writer_open_with_params

* params.warnUnusedParameters

* VideoCaptureParameters in GStreamer

* open_with_params

* params->getUnused

* Reduce PSNR threshold 33->32 (other tests use 30)

* require FFMPEG 4.0+; PSNR 30 as in other tests

* GStreamer AVI-demux plugin not installed in Ubuntu test environment?

* fix build on very old ffmpeg

* fix build on very old ffmpeg

* fix build issues

* fix build issues (static_cast)

* FFMPEG built on Windows without H264 encoder?

* fix for write_nothing test on VAAPI

* fix warnings

* fix cv_writer_get_prop in plugins

* use avcodec_get_hw_frames_parameters; more robust fallback to SW codecs

* internal function hw_check_device() for device check/logging

* two separate tests for HW read and write

* image size 640x480 in encode test

* WITH_VA=ON (only .h headers used in OpenCV, no linkage dependency)

* exception on VP9 SW encoder?

* rebase master; refine info message

* videoio: fix FFmpeg standalone plugin build

* videoio(ffmpeg): eliminate MSVC build warnings

* address review comments

* videoio(hw): update videocapture_acceleration.read test

- remove parallel decoding by SW code path
- check PSNR against the original generated image

* videoio: minor fixes

* videoio(test): disable unsupported MSMF cases (SW and HW)

* videoio(test): update PSNR thresholds for HW acceleration read

* videoio(test): update debug messages

* "hw_acceleration" whitelisting parameter

* little optimization in test

* D3D11VA supports decoders, doesn't support encoders

* videoio(test): adjust PSNR threshold in write_read_position tests

* videoio(ffmpeg): fix rejecting on acceleration device name mismatch

* videoio(ffmpeg): fix compilation USE_AV_HW_CODECS=0, add more debug logging

* videoio: rework VideoAccelerationType behavior

- enum is not a bitset
- default value is backend specific
- only '_NONE' and '_ANY' may fallback on software processing
- specific H/W acceleration doesn't fallback on software processing. It fails if there is no support for specified H/W acceleration.

* videoio(test): fix for current FFmpeg wrapper
