As specified in Google Congestion Control we should run the packet loss
estimation algorithm "every time feedback from the receiver is
received".
And, also as defined by GCC, we now have 2 different estimated bitrates,
one for the delay-based controller value and one for the loss-based one,
and we use the minimum value between those 2 as our current estimation.

1. Working scenario:
T1 -> Caps event (all caps have been received)
T1 -> Start discovering
T2 -> Change state to Playing
T2 -> The signaller is not started as:
- Sink current_state() == Paused as it will be set to
playing after the change_state vmethod returns
- Discovery is not done anyway
T1 -> Discovery is done
=> The signaller is started, and **everything works well**.
2. Failing scenario:
T1 -> Caps event (all caps have been received)
T1 -> Start discovering
T1 -> Discovery is done
T1 -> The signaller is not started as:
- Current state == Paused (it will be set to playing
after the change_state vmethod returns)
- Discovery is not done anyway
T2 -> Change state to Playing
T2 -> The signaller is not started as:
- Sink current_state == Paused as it will be set to
playing after the we return from the change_state
vmethod
In that case the signaller never starts.
Writing a proper "depfile" to follow depending files, based on depfiles
generated by rustc.
This is based on work done while working on gobject-examples-rs
The element has a small race condition where it might output two buffers
with the same running time during e.g. a manual switch. In practice this
is not a problem, so the test takes this race into account.

This new video filter is able to detect the dominant color in a video frame.
When the color has changed from the previous frame the filter posts an Element
message on the bus, the associated structure is named `colordetect` and has two
fields:
* a string field named `dominant-color`
* a list field containing the whole color palette, stored as uint values, sorted
by dominance, with more dominant colors first
Also clip raw audio/video buffers according to the caps if they have the
relevant information in the caps, and drop raw audio samples if they're
outside the segment too.
In addition also set durations on raw audio/video buffers based on the
caps if no duration is set.
fallbackswitch might forward flush event if it's for the currently
active pad. But forwarded flush event will be problematic in various
reasons and that's not a behavior we expected.
