fbceaab941 utils: streamproducer: add API to retrieve last sample from producer
This may be used for example to easily generate thumbnails from video
producers.

0e17878bed utils: streamproducer: add API to retrieve pushed and dropped buffers
This may be used by applications to compute statistics about the overall
pipeline health, like the ratio of buffers dropped.

5349822962 utils/streamproducer: add ConsumptionLink
Having an explicit link object makes it much easier to build complex
producers/consumers dynamics graphs.
It provides helper to switch producers and prevent accidentally keeping
broken links around as they are disconnected on Drop.

f68efd0cab utils/streamproducer: add API to not forward eos to consumers
User may want to plug another producer when one is eos, in such case we
don't want to propagate eos to consumers.

a51235048d utils/streamproducer: Add StreamProducer::configure_consumer()
This allows configuring an `appsrc` before actually adding it as
consumer at a later time, and can be useful if the pipeline with the
source should be started earlier than adding it to a consumer.

Also use strongly-typed property API for the `appsrc` properties.

f3bba21faa Introduce StreamProducer
Introduce a new `gstreamer-utils` crate where we implement a
`StreamProducer` structure that allows "producing" pipeline (Producers)
pushing their data to 0 or several "consuming" pipelines. The Producer
needs to push their data to an `appsink` which the `StreamProducer` controls
and the "consumer" pipelines need to have an AppSrc which the same
StreamProducer controls.

It allows similare behavior as a `tee` element but with a simpler to
handle addition and removal of "consumers" as well as a total decoupling
of the various consumer, both between each others and the producer
pipeline.

This has simply been extracted from
