jpegdec: Support libjpeg-turbo colorspace conversion

The libjpeg-turbo has a built-in support for performing colorspace
conversion. The performance of this conversion is much better than
doing the same separately using videoconvert. Implement support for
this conversion to RGBx/xRGB/BGRx/xBGR formats. Other formats can
be easily added later.

- The decoding of various pixel formats can be tested and compared to
  non-libjpeg-turbo decoding as follows:
  for gfmt in {RGB,BGR}{,x} x{RGB,BGR} ; do
      echo "$gfmt"
      gst-launch-1.0 -q \
          videotestsrc pattern=colors ! \
          video/x-raw,format=${gfmt} ! \

  Notice how the alpha channel is set to arbitrary value in case of the
  libjpeg-turbo decoding into RGBx/BGRx/xRGB/xBGR pixel formats. This is
  documented in libjpeg-turbo README.md as follows:
    "
    When using the RGBX, BGRX, XBGR, and XRGB colorspaces during decompression, the
    X byte is undefined, and in order to ensure the best performance, libjpeg-turbo
    can set that byte to whatever value it wishes.
    "

splitmuxsink: Keep track of the pending input GOPs in a queue

This cleans up input GOP handling and makes it possible to handle more

splitmuxsink: Handle frame reordering due to B frames better

Instead of assuming that the PTS of a keyframe is the lowest PTS of a
GOP, wait until the DTS has passed this PTS and take the minimum PTS up
to that point. That way the minimum PTS of a GOP can be determined, at
least for closed GOP streams. Open GOP streams still can't be handled
properly.

By knowing the minimum PTS of each GOP, keyframes can be requested at
the correct time relative to the GOP (and thus fragment) start and
fragment overflow calculations can calculate the correct durations of
the GOPs.

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.

ges:uri-asset: Ignore streams with no ID

Since 0d95d9258b97 we respect the asset stream-id in `GESUriSource` so
we can not work with unknown or broken stream ID in the assets.

We just ignore them, warning about it and we should fix that in
demuxer so they don't expose pad without providing a stream id for them.

typefindfunctions: differentiate h265 from h264

in some cases, the algo gives the same probability
to h264 and h265 for h26x stream resulting in a h265
stream detected as a h264.
if sps/pps/vps detected, increase the probabilty.

va: meson: Update and enhance meson syntax usage.

This patch contains two updates:

1. Instead of checking for dependency already checked just to verify a
   version, we use the dependency version API.
2. Update the deprecated function get_pkgconfig_variable.

msdk: meson: Don't get dependency variable before it's valid.

It's possible to have installed MediaSDK environment
package (libmfx-dev in Debian) without libva environment package. This
setup will lead to a breakage of meson configuration.

The fix is to get the libva's driver directory variable after the
dependency is validated as found.

ristsink: set sync to FALSE on RTCP sink

rtpsink: set sync off on rtcp_sink

When using the following setup (the error can be reproduced using
simpler sender pipelines), the receiver resynchronises the clock on RTCP
packets. The effect was that a couple seconds were cut out of the
playback because an initial RTCP packet was dropped.

When sending out all RTCP packets (setting sync=FALSE on the RTCP
updsink), the playback is fine.

This syncs rtpsink with rtpsrc (where this property was already set).

actually check for non-zeroness.

Fix gitignore

- `*build*/` is not needed because Meson puts a .gitignore in builddir
already.

- `meson/` why?

- `/gst*` is too wide, it includes e.g. gst-env.py, list symlinks
explicitly instead.

- `subprojects/*` excludes all .wrap files, and `!subprojects/gst*` is
not enough because e.g. `macos-bison-binary` is still ignored. Instead
ignore only directories except those we include in our git repository.
