15519ebe3d legal: add per-file authorship information.
Credit original authors on a per-file basis as we cannot expect people
to know all country-specific rules, or bother browsing through the git
history.

06c7fde8e0 filter: fix semantics of deinterlacing flags.
Fix deinterlacing flags to make more sense. The TFF (top-field-first)
flag is meant to specify the organization of reference frames used in
advanced deinterlacing modes. Introduce the more explicit flag TOPFIELD
to specify that the top-field of the supplied input surface is to be
used for deinterlacing. Conversely, if not set, this means that the
bottom field of the supplied input surface will be used instead.

944a7bd077 filter: add initial support for deinterlacing.
Add basic deinterlacing support, i.e. bob-deinterlacing whereby only
the selected field from the input surface is kept for the target surface.
Setting gst_vaapi_filter_set_deinterlacing() method argument to
GST_VAAPI_DEINTERLACE_METHOD_NONE means to disable deinterlacing.

Also move GstVaapiDeinterlaceMethod definition from vaapipostproc plug-in
to libgstvaapi core library.

d633e0d072 surface: add new chroma formats.
Add new chroma formats available with VA-API >= 0.34.0. In particular,
this includes "RGB" chroma formats, and more YUV subsampled formats.
Also add a new from_GstVaapiChromaType() helper function to convert
libgstvaapi chroma type to VA chroma format.

2d2334afed overlay: add support for global-alpha.
Handle global-alpha from GstVideoOverlayComposition API. Likewise,
the same code path could also work for premultiplied-alpha but this
was not tested.

1307a5b4ef subpicture: add premultiplied-alpha and global-alpha feature flags.
Add premultiplied-alpha and global-alpha feature flags, along with converters
between VA-API and gstreamer-vaapi definitions. Another round of helpers is
also necessary for GstVideoOverlayComposition API.

a79c7f9fa6 decoder: optimize slice data buffers initialization.
VA drivers may have a faster means to transfer user buffers to GPU
buffers than using memcpy(). In particular, on Intel Gen graphics, we
can use pwrite(). This provides for faster upload of bitstream and can
help higher bitrates.

vaapi_create_buffer() helper function was also updated to allow for
un-mapped buffers and pre-initialized data for buffers.
