8b54c3fed6 ts/Task: split iterate into try_next and handle_item
Previous Task iteration model suffered from the following
shortcomings:

- When an iteration was engaged it could be cancelled at
  await points by Stop or Flush state transitions,
  which could lead to inconsistent states.
- When an iteration was engaged it could not be cancelled
  by a Pause state transition so as to prevent data loss.
  This meant we couldn't block on the Pause request because
  the mechanism couldn't guarantee Paused would be reached
  in a timely manner.

This commit split the Task iteration into:

- `try_next`: this function returns a future that awaits
  for a new iteration to begin. The regular use case is
  to return an item to process. The item can be left to
  `()` if `try_next` acts as a tick generator. It can
  also return an error. This function can be cancelled at
  await points when a state transition request occurs.
- `handle_item`: this function is called with the item
  returned by `try_next` and is guaranteed to run to
  completion even if a transition request is received.

Note that this model plays well with the common Future
cancellation pitfalls in Rust.

d4061774a4 ts/Task: return a future for state transitions
State transitions request functions hid the synchronization
details to the caller:

- If the transition was requested from a Context, a subtask was
  added or the transition ack was not awaited if the new transition
  was requested from a running transition or an iteration function.
- If the transition was not requested from a Context, current
  thread was blocked until the ack was received.

This strategy facilitated code in elements, but it suffered from
the following shortcomings:

- The `prepare` transition request didn't comply with the above
  strategy and would always return an `Async` form. This was
  designed to accomodate the `Prepare` function for elements
  such as `ts-tcpclientsrc` which takes times due to the
  TCP socket connection delays. The idea was that the actual
  transition result would be available after calling `start`.
  This was a disadvantage for elements which would prefer to
  error immediately in the event of a preparation failure.
- Hidding the transition request synchronization to the caller
  meant that they had no options but relying on the internal
  mechanism. E.g.: it was not possible to `start` from another
  async runtime without blocking. Also it was not possible
  to request a transition and choose not to await for the
  ack.

This commit introduces a more flexible API for state
transitions requests:

- The transition request function now return a `TransitionStatus`,
  which is a Future.
- When an error occurs immediately (e.g. the transition
  request is not autorized due to current state of the Task),
  the `TransitionStatus` is resolved immediately and can be
  `check`ed for errors. This is useful for functions such as
  `pepare` in the case of `ts-tcpclientsrc` (see above).
  This is also useful for `pause`, because in current design,
  the transition is always async. Note however, that `pause` is
  forseen to adhere to the same behaviour as the other transition
  requests in the near future [1].
- If the caller chooses to await for the ack and they don't know
  if they are running on a ts Context (e.g. in `Pad{Src,Sink}`
  handlers), they can call `await_maybe_on_context`. This is mostly
  the same behaviour as the one that used to be performed internaly.
- If the caller knows for sure they can't possibly block an async
  executor, they can call `block_on` which is more explicite, but
  will nonetheless make sure no ts Context is being blocked. This
  last check was introduced as it was considered low overhead
  while it should ease preventing missues in cases where the above
  functions should be used.

625fce3934 ts/Task: spawn StateMachine on ts Context
Task state machines used to execute in an executor from the Futures
crate. State transitions actions and iteration functions were then
spawned on the target threadshare Context.

This commit directly spawns the task state machine on the threadshare
Context. This simplifies code a bit and paves the way for the changes
described in [1].

Also introduces struct `StateMachineHandle`, which gather together
fields to communicate and synchronize with the StateMachine. Renamed
`StateMachine::run` as `spawn` and return `StateMachineHandle`.

a triggering event is pushed. This can cause throttling to induce

374671cb6f ts/udpsink: fix default clients not leading to socket configuration
During MR !793, the socket configuration mechanism was changed to
use commands passed to the Task via a channel. This worked properly
for user changes via settings and signals, however the default
clients setting was not used.

A simple solution could have been to send a command at initialization
to add the default clients, but it was considered a better solution
to just wait for the Task preparation to configure the sockets based
on the value of settings.clients at that time, thus avoiding
unnecessary successive removals and additions of clients which could
have happened before preparation.

Of course, users can still add or remove clients as before, before
and after Task preparation.

64f664c859 plugin: Implement bandwidth estimator based on the Google Congestion Control algorithm
See https://datatracker.ietf.org/doc/html/draft-ietf-rmcat-gcc-02

This commit implements the bandwidth estimation as a GStreamer element
that is then used in webrtcbin through the new `request-bandwidth-estimator`
signal.

This keeps our Homegrown congestion controller but removes the possibility
to switch CC algorithm at runtime.

d240bbc4e2 aws_transcriber: Fix regression with credentials mechanism
A regression was introduced during the migration to AWS SDK. One used
to be able to provide credentials in multiple ways with the earlier
Rusoto ChainProvider (config file / environment variables). Now one
has to explicitly set the properties.

Use the DefaultCredentialsChain from AWS SDK to restore the previous
functionality.

c53e5b8bb2 Allow passing free form metadatas about consumers/producers/listenners
In some applications people might need to be able to pass more metadata
than the only "display-name" this commit allow that by adding a field in
all signalling structure where it is free form json and removing the
"display-name" as the free form `meta` field allows application to pass
this kind of information without any problem.

On the "webrtcsink" side this commit adds a `meta` property as a
gst::Structure which will be passed as a json string to the signalling
server so we enforce data to be structured.

6a2df92453 Revert "fmp4mux: Dequeue as many buffers as are available in each aggregate call"
This reverts commit 402500f79c.

This commit introduces race conditions. It was intended as solving
an issue with some pipelines which had their queues filling up,
causing the streams to stall. It is reverted as this solution is
considered a workaround for another issue.
