video: Fix scaling in 4x horizontal co-sited chroma

4x downscaling of chroma with co-sited chroma has never worked
it seems.

Fixes incorrect videotestsrc output and videoconvert conversions
to Y41B, YUV9, YVU9 and IYU9 with co-sited chroma.

e.g.
gst-launch-1.0 videotestsrc ! video/x-raw,format=Y41B,width=1280,height=720 ! \
  videoconvert ! autovideosink

stream-start event and queued up a buffer in the meantime.

This still leaves a race condition where the srcpad task sees all pads
in EOS state and finishes the stream, while shortly afterwards a pad
might receive a stream-start event again, but this doesn't seem to be

This is currently causing a warning because we do not require the
version of meson that ships with this feature: 0.63.0. The version has
not been bumped because older Meson versions gracefully ignore the
wrap field, this fix is optional and only needed on macOS, and 0.63.0
is a very new release with a bug that partially breaks this feature:

 in the [GCC] algorithm for example.

Bandwidth estimator element are placed right before the "RTPSession" as

Congestion Control" RTCP feedback messages through the "RTPTwcc" custom
events that are sent by the rtpsession.

Applications are responsible to react to the bandwidth estimator element
and set the encoder target bitrate etc... which means that we can not
pass an estimator as an element factory, so a signal as been chosen

base: lookup RGB format without alpha

librfb requests a colour space for depth 32 and bpp 32 with alpha set to
0x0, treat this the same as depth 24 with bpp 32.

python: Add a Gst.init_python function to be called from plugins

Plugins know that they will be initialized after Gst was initialized

python: Do not call gst_init when it is already is_initialized

GStreamer plugins written in python need to call `Gst.init` to ensure
that GStreamer is initialized so when loading a python plugin, we might
be recursively calling `gst_init` which is not a good idea.

videoconvertscale: ensure writable caps when fixating format

gst_video_convert_scale_get_fixed_format() receives 'othercaps' from
basetransforms' fixate_caps() vmethod which explicitly mentions that
'`othercaps` may not be writable'.

The gst_caps_intersect() call just before may or may not produce new
caps. Particularly in cases like EMPTY or ANY caps on either of the
inputs, only a ref is taken and returned to the caller.

As a result, gst_video_convert_scale_fixate_format() may have attempted
to modify a non-writable caps structure.

Fix by adding a gst_caps_make_writable().
