The number of frames is only meaningful with audio as a VideoData always contain a single frame.
So we only have this member in AudioData, which will simplify the logic in a future commit where the number of frames present depends on the trimming filter applied.

Rework our mp4 sample iterator to handle cbcs crypto data.
To support this we populate the following new data for samples:
- Crypto pattern information, this is split into a count of encrypted blocks
and a count of clear blocks.
- A constant IV.
This information is available at a track level and a sample group level. The
sample group level supersedes track level information if both a present.
Prior to this patch, some crypto information was written to samples in
the SampleIterator in Index.cpp, and some in the MP4Demuxer (based on if the
SampleIterator had not populated the data). This patch moves all these
operations into the SampleIterator -- the idea being that the sample iterator
should be the component responsible for setting up sample meta data.

Explicitly store the crypto scheme being used on our crypto structs to let us
differentiate between cenc and cbcs data. In doing so remove mMode and replace
mValid with IsEncrypted() for the following reasons:
- Different modes within the existing schemes are not currently utilized by the
spec: the scheme implies mode. Having a mode and a scheme could lead to confusion
between the two. We can return mMode if ever needed by the spec --
possibly if the isProtected flag which we were tracking with mMode, is
ever changed to be more than a bool in the spec.
- mValid was typically used to check if these structs contained valid crypto
data or not. With only one scheme this was often shorthand for 'IsEncrypted',
but with multiple schemes what is considered valid data for one may not be for
another. Do away with this and just explicitly have an 'IsEncrypted'.

The documentation says that the boolean return values from these methods
must be checked. We might as well make the compiler check these things
for us.
Returning UniquePtr is nicer than returning raw pointers, and has the
nice side effect of forcing us to clean up the uses of nsAutoPtr that
were hanging about.
There is only declaration but no definition.
Also, there is no caller. Remove it.

We detect when a PSSH is contained in a MOOF and stash them in the
mp4_demmuxer::Moof object. When the mp4_demuxer::SampleIterator returns a
sample, we check whether it's the first sample from its MOOF, and if so, we
attach any PSSH boxes from that MOOF to the sample. The TrackBuffersManager
checks samples upon demux, to see whether they have any EME init data attached,
and if so dispatches thoses to the HTMLMediaElement in 'encrypted' events.

The way we pass in AudioDataValue arrays into AudioData is non-uniform:
sometimes we have nsAutoArrayPtrs, sometimes we don't, and it's not
immediately obvious from the function signature of the constructor that
we're actually taking ownership of this array. Let's fix that by using
UniquePtr<AudioDataValue[]> smart pointers to hold the data prior to
creating AudioData values, and for passing in to AudioData's
constructor. Using standard-er C++ things instead of our homegrown ones
is a good thing.
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.

MediaRawData is often kept to store small data that is unlikely to change over the lifetime of the MediaRawData.
The use of nsTArray as memory backend comes at a cost of much greater memory allocated than required.
Additionally, a MediaRawData was configured to allocate a minimum size of 4kiB.
While this made sense for our past use of MediaRawData, the new MSE keeps big arrays of them to keep audio and video samples.
Combined with the nsTArray overheads, our actual memory use was 22 times greater than thought.
A source buffer allow 100MiB worth of samples, resulting in an actual memory usage of 2.2GiB.

This makes normal playback consistent with the buffering state, which already
does this. We'll also need this when we handle multiple images, because then
we need to hande the entire queue of images to the ImageContainer without
pulling any of them off the queue.
