if the format is not correct.

When we seek in a webm containing an alpha channel, the first frame of a cluster may not be a keyframe for both channels. So seek backward until we find one.
We limit such operation on video with an alpha channel to prevent potential regression (even though thoses files would technically be invalid)

The nsRect.h and nsSize.h headers typedef nsIntRect to gfx::IntRect etc, so the
rect/size objects we use will be the same, just under a different name.
However the old headers #include a bunch of things we don't use, so we if we
use the gfx objects directly we end up with a smaller include graph.

We have three implementations, in the MP4, WebM and MediaSource decoders. The
WebM and MP4 are the same. Ogg and other decoders don't have an implementation,
but if we create a default implementation in MediaDecoder, they'll get it for
free. MediaSourceDecoder needs a custom override still.

This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.

When av1 video playback is enabled, declare it as supported
in the webm container in MediaSource.IsTypeSupported.
Also support special mime types of the form
video/webm; codecs=vp9.experimental.<git-commit-id>

while the av1 bitstream is under development.

There's no way to verify locally the while loop will execute and set the return value, so we get an uninitialized variable warning.
Initialize it at declaration time to failure, relying on the later code to override with success.
Actually, it doesn't matter what we initialize it to, since the while loop will never terminal if GetNextPacket somehow returns success without pushing a new packet onto the sample array. But this silences the warning.
