- to reduce binaries size of FFmpeg Windows wrapper
- MinGW linker doesn't support -ffunction-sections (used for FFmpeg Windows wrapper)
- move code to improve locality with its used dependencies
- move UMat::dot() to matmul.dispatch.cpp (Mat::dot() is already there)
- move UMat::inv() to lapack.cpp
- move UMat::mul() to arithm.cpp
- move UMat:eye() to matrix_operations.cpp (near setIdentity() implementation)
- move normalize(): convert_scale.cpp => norm.cpp
- move convertAndUnrollScalar(): arithm.cpp => copy.cpp
- move scalarToRawData(): array.cpp => copy.cpp
- move transpose(): matrix_operations.cpp => matrix_transform.cpp
- move flip(), rotate(): copy.cpp => matrix_transform.cpp (rotate90 uses flip and transpose)
- add 'OPENCV_CORE_EXCLUDE_C_API' CMake variable to exclude compilation of C-API functions from the core module
- matrix_wrap.cpp: add compile-time checks for CUDA/OpenGL calls
- the steps above allow to reduce FFmpeg wrapper size for ~1.5Mb (initial size of OpenCV part is about 3Mb)

* 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
