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.

08cb5b482d libs: Introduce GstWinRT library 
Adding a helper library for various WinRT specific implementations.
Currently this library supports only DeviceWatcher abstraction object
which can be used for dynamic device add/remove detection.

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.
