e96687d88d d3d11: Update build-time dependency
Remove all the d3d11 and dxgi header version dependent ifdef
and bump the minimum requirement to d3d11_4.h and dxgi1_6.h.
We are already failing support old Visual Studio (Windows SDK actually)
such as Visual Studio 2015. Note that our MinGW toolchain satisfies
the requirement.

From runtime point of view, this change should be fine since
we are checking OS version with IUnknown::QueryInterface()
everywhere in order to check API availability

1. Use api_version variable rather than static string.

5e4c152de4 va: Remove libgudev crumbs in library.
In commit e699aaeb we moved linking of libgudev to the plugin rather
the library, because it's only used in the plugin. But the dependency
check is still done in library.

This patch removes the dependency check in library, and updates the
dependency check in plugin.

6434d69f8c codecs: Stop claiming constness for refcounted object
It's almost pointless and makes little sense as subclass might
want to modify refcount of the object or so. And all subclasses
are already casting them to non-const version as well.

168ad9f58f codecparsers: h265parser: Verify all possible profiles.
It's possible a HEVC stream to have multiple profiles given the
compatibility bits. Instead of returning a single profile, internal
gst_h265_profile_tier_level_get_profiles() returns an array with all
it possible profiles.

Profiles are appended into the array only if the generated profile
is not invalid.

gst_h265_profile_tier_level_get_profile() is rewritten in terms of
gst_h265_profile_tier_level_get_profiles(), returning the first
profile found the array.

And  gst_h265_get_profile_from_sps() is also rewritten in terms of
gst_h265_profile_tier_level_get_profiles(), but traversing the array
verifying if the proposed profile is actually valid by Annex A.3.x of
the specification.

There are a lot of info in the mpeg2's sequence(also including ext
display_ext and scalable_ext). We need to notify the subclass about
its change, but not all the changes should trigger a drain(), which
may change the output picture order. For example, the matrix changes
in sequence header does not change the decoder context and so no need
to trigger a drain().

a8decde6d3 codecs: gstmpeg2decoder: add support for render delay
Some decoding APIs support delayed output for performance reasons.
One example would be to request decoding for multiple frames and
then query for the oldest frame in the output queue.
This also increases throughput for transcoding and improves seek
performance when supported by the underlying backend.

Introduce support in the mpeg2 base class, so that backends that
support render delays can actually implement it.

e699aaeb16 va: meson: Move back libgudev dependency to plugin.
When move the libgstva, libgudev dependency was moved as part of the
library, though it's not use by the library but the plugin. This patch
moves back libgudev dependency to the plugin.

Also HAVE_LIBDRM is move to the library which is the one who use it.

c6ec7f3ea4 codecs: vp9decoder: add support for render delay
Some decoding APIs support delayed output for performance reasons.
One example would be to request decoding for multiple frames and
then query for the oldest frame in the output queue.

This also increases throughput for transcoding and improves seek
performance when supported by the underlying backend.

Introduce support in the vp9 base class, so that backends that
support render delays can actually implement it.

c3a161f287 basetsmux: rework SCTE section handling to handle passthrough
mpegtsmux can receive SCTE sections from two origins: events
created by the application, and events forwarded downstream by
mpegtsdemux, containing sections that may not have been fully
parsed, and additional data to help tsmux translate times to
the correct domain, both for requesting keyframes and calculating
an accurate pts_adjustment.

The complete approach is documented further in a comment above
the relevant function.
