5ca033049e ts/pad: use gst::Pad in handlers trait functions...
... instead of the `Pad{Src,Sink}Ref` wrappers:

- In practice, only the `gst::Pad` is useful in these functions.
  Some of these which need a `Pad{Src,Sink}Ref`, but it's the one
  for the opposite stream direction. In those cases, it is accessed
  via the element's implementation.
- It saves a few `clone`s.
- The implementations usually use the `gst::Pad` for logging.
  They no longer need to access it via `pad.gst_pad()`.

554ce7e7d6 ts/pad: don't pass self as ref in remaining handler traits functions
- They are either unit types or `Clone` (in which case they are implemented
  as pointers).
- Internally, we already use an owned version, so there's no need to get a
  reference.
- It facilitates implementation if the handler must be moved into a closure
  or a `Future`.

6319d104a8 Take advantage of Into<Option<_>> args
Commit 24b7cfc8 applied changes related to nullability as declared
by gir. One consequence was that some functions signature ended up
requiring users to pass `Some(val)` when they could use `val`
before.

This commit applies changes on `gstreamer-rs` which, will honoring
the nullability stil allow users to pass `val` for the few affected
functions.

This commit also fixes the signature for `Element::request_new_pad`
which was updated upstream.

2bffdec691 ts: better use of imp & elem args in Pad{Sink,Src}Handlers
This is a follow-up to commit 7ee4afac.

This commit cleans up the `Pad{Sink,Src}Handler` by

- Keeping arguments which are strictly necessary.
- Passing arguments by value for the trait functions which return
  a `Future`. The arguments which were previously passed by reference
  were `clone`d internally and then `clone`d again in most
  implementations.

There are unfortunate differences in trait function signatures
between those which return a `Future` and the sync functions. This
is due to the requirement for the arguments to be moved to the
resulting `Future`, whereas sync functions can rely on references.
One particular notable difference is the use of the `imp` in sync
functions instead of the `elem` in functions returning a `Future`.
Because the `imp` is not guaranteed to implement `Clone`, we can't
move it to the resulting `Future`, so the `elem` is used.

bc5b51687d fix formatted values constructors

bd14e476f1 Fix direct access to the inner specific formatted values
This is no longer available as this could lead to building a defined
value in Rust which could be interpreted as undefined in C due to
the sentinel `u64::MAX` for `None`.

Use the constants (e.g. `ONE`, `K`, `M`, ...) and operations to build
a value and deref (`*`) to get the quantity as an integer.

36ce8bd4f7 fmp4mux: Implement a better strategy for splitting fragments and deciding which buffers go into which fragment
It is now guaranteed that each fragment is at most fragment-duration
long unless the one and only GOP of the fragment is longer than that.
The first (non-EOS) stream determines the duration of each fragment and
all other streams are drained to at most the fragment end timestamp
determined this way.

In addition the next fragment's target time is now at the end of the
previous fragment plus fragment-duration instead of using
  first-fragment + N*fragment-duration
regardless of where fragments were split before.

That is, fmp4mux now uses the same strategy as used by splitmuxsink and
as is required e.g. by HLS with regards to the target duration.

1be30b8ecc ts/scheduler: fix shutdown
A strong handle reference was held in the `block_on_priv` `Result`
handler in the thread for the `Scheduler::start` code path, which
lead to the `Handler` strong count not dropping to 0 when it
should, leading to the shutdown request not being triggered.

Use an Arc<AtomicBool> instead of a oneshot channel for shutdown.
The main Future is always polled and never relies on a waker, a
`poll_fn` is cheap and does the job.

Unpark the scheduler after posting a request to shutdown.

d39aabe054 ts/Task: don't drain sub tasks after state transition and iteration
Subtasks are used when current async processing needs to execute
a `Future` via a sync function (eg. a call to a C function).
In this case `Context::block_on` would block the whole `Context`,
leading to a deadlock.

The main use case for this is the `Pad{Src,Sink}` functions:
when we `PadSrc::push` and the peer pad is a `PadSink`, we want
`PadSrc::push` to complete after the async function on the
`PadSink` completes. In this case the `PadSink` async function
is added as a subtask of current scheduler task and
`PadSrc::push` only returns when the subtask is executed.

In `runtime::Task` (`Task` here is the execution Task with a
state machine, not a scheduler task), we used to spawn state
transition actions and iteration loop (leading to a new
scheduler Task). At the time, it seemed convenient for the user
to automatically drain sub tasks after a state transition action
or an iteration. User wouldn't have to worry about this, similarly
to the `Pad{Src,Sink}` case.

In current implementation, the `Task` state machine now operates
directly on the target `Context`. State transtions actions and
the iteration loop are no longer spawned. It seems now useless to
abstract the subtasks draining from the user. Either they
transitively use a mechanism such as `Pad{Src,Sink}` which already
handles this automatically, or they add substasks on purpose, in
which case they know better when subtasks must be drained.

61c62ee1e8 ts/timers: multiple improvements
This commit improves threadshare timers predictability
by better making use of current time slice.

Added a dedicate timer BTreeMap for after timers (those
that are guaranteed to fire no sooner than the expected
instant) so as to avoid previous workaround which added
half the max throttling duration. These timers can now
be checked against the reactor processing instant.

Oneshot timers only need to be polled as `Future`s when
intervals are `Stream`s. This also reduces the size for
oneshot timers and make user call `next` on intervals.
Intervals can also implement `FusedStream`, which can help
when used in features such as `select!`.

Also drop the `time` module, which was kepts for
compatibility when the `executor` was migrated from tokio
based to smol-like.

235ded35fd ts: add feature to add counters for performance evaluation
Add a `tuning` feature which adds counters that help with performance
evaluation. The only counter added so far accumulates the duration a
Scheduler has been parked, which is pretty accurate an indication of
CPU usage of the Scheduler.

2355be1cef ts/jitterbuffer: extra robustness for Windows CI
jitterbuffer tests crash on Windows CI sometimes. Activating logs
showed time values which are probably not expected in a regular
environment, but which can happen there. Adding extra robustness
to `next_wakeup` computation seems to fix the problem judging by
the few runs I triggered.

2bb071a950 ts/runtime: slight optimizations for sub tasks related operations
Using callgrind with the standalone test showed opportunities for
improvements for sub tasks addition and drain.

All sub task additions were performed after making sure we were
operating on a Context Task. The Context and Task were checked
again when adding the sub task.

Draining sub tasks was perfomed in a loop on every call places,
checking whether there were remaining sub tasks first. This
commit implements the loop and checks directly in
`executor::Task::drain_subtasks`, saving one `Mutex` lock and
one `thread_local` access per iteration when there are sub
tasks to drain.

The `PadSink` functions wrapper were performing redundant checks
on the `Context` presence and were adding the delayed Future only
when there were already sub tasks.
