Some file format standards don't require mastering-display-info
and content-light-level values to be provided.
Decklink however requires the static HDR metdata for the PQ transfer
function which we may not have.
CTA-861-G mentions that in this case, 0 may provided as an 'unknown'
value which is what we use here.

* Consistently name parse functions according to their message type and
deprecate the misnamed ones,
* Add missing parse functions,
* Check for the correct message type when parsing
* Use correct field name for warning message details

If a stream has an 'irregular' frame rate (e.g. metadata) RTCP SR
may be generated way too early, before the RTPSource has received
the first packet after Latency was configured in the pipeline.
We skip such RTPSources in the RTCP generation.

This is documented as:

... but was not implemented.
This also respects the `notify::silent` property for the notify signals
to be less intrusive.

Instead of registering the whole list of formats associated to a chroma, our
experience with GstVA tells that entry points only handles one color format per
supported chroma, and they are reflected in the static table.
This avoids exposing unsupported color formats for negotiation.

* Move the exported PATH variables into a script so
we can source it in all the wrapper scripts.
* Add a guard to only copy over the cache when the
SUBPROJECTS_CACHE_DIR variable is set, which only
happens on CI by default
* Make it possible to run the scripts with default
values for some of the variables, like WERROR and MESON_ARGS.

There is the possibility than an element/code/helper creates an identical
`GstStream` (same type and stream-id) instance instead of re-using a previous
one.
For those cases, when detecting whether a `GstStream` is already present in a
collection, we need to do more checks than just comparing the pointer.

If we can't get the current caps when receiving a stream-start, that's fine,
they can/will be provided by other means at a later time.
What we definitely should not do is provide the starting caps of the chain,
which are potentially completely different from the end ones (like for example
`application/x-rtp`)

If an encoder supports multiple codecs (a bin wrapping/auto-plugging encoders)
then its src pad template caps might list the supported codecs. Without this
patch the selected parser would be the one corresponding to the first codec,
leading to caps negotiation error later on. The proposed fix is to check the
media type on the parser candidates sink pad templates according to the
requested encoded format.
