Remove string comparisons to determine from mime types if content is VPX or
H264. Replace with calls to VPXDecoder::IsVPX or MP4Decoder::IsH264 to
centralise such logic.
This patch introduces MP4Decoder:IsH264, and moves the similar functionality out
of H264Convertor for the sake of consistently having these functions in
decoders.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

Update C++ caller code for for mp4parse 0.4.0. Now feeds data through
a read callback in mp4parse_io.
Hook up the GetTrackInfo method to the rust demuxer results.
Prefer rust demuxer only if there's an Opus track.
Fill in audio and video track metadata. Pass audio codec_specific_config
to the decoder.
With this change sample.mp4 plays.

Extract all the parameters passed to CreateAudioDecoder/CreateVideoDecoder and
place them into a structure that is passed down to the creation of the actual
decoder, where the relevant parameters can be extracted.
This makes it easier to add more arguments to the Create*Decoder calls in future.

PDMFactory will automatically load and initialize the required frameworks upon first use.
Also fix constness of some methods.

Pass declared-but-yet-undefined DecoderDoctorDiagnostics pointer to various
routines that contribute to deciding if a media format can be played, and
those that create decoders.
Points where a DecoderDoctorDiagnostics can be injected are currently marked
with "/* DecoderDoctorDiagnostics* */ nullptr", and some will be used in
following patches.

When running gtest, none of the prefs actually exist, so we end up having most PDMs disabled.

We now use an index of samples made of block of samples delimited by keyframes. The search is performed using a binary search. This allows to quickly find which blocks are found within the media cache.
On a 8 core mac pro, this leads to a 67% improvement on CPU time spent playing a long MP4 video (from 112s CPU to 45s CPU)
The optimisation is only possible if all mp4 data chunks are continuous (which they almost always are)
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

The LayersBackend can be defined at construction time, however if a parent MediaDecoder exists, the value will be overwritten by the MediaDecoderOwner value.

The PDMFactory will run more accurate checks based on the TrackInfo object and will fail to create a decoder if the type is unsupported. So use that instead
