This implements the idea of automatically setting a content proc's
render root based on the render root enclosing the iframe that
points to it. There was a bit of cleanup in here that was a bit
tricky to extract from the core patch revolving around how we
use the Api(...) helper. This was to avoid the situation where
we use the Api(...) helper before our render root is initialized,
when we don't actually have to. I.e., when we just want the root
WebRenderAPI in all cases.
An alternative to this approach could be to fully built out the
WebRender transactions and just queue those up to be sent. However,
transaction building has various side effects which are committed
before the transaction is actually sent, so we would have to build
out some scheme for deferring those as well. This seemed simpler.

This splits out the inner bit of RecvEmptyTransaction to just iterate over
the documents once, rather than iterating over them individually. Originally
I ran into difficulties with this and then left it on the table, but I think
it was enabled by splitting out the epochs in pipeline info by renderroot.

I needed empty blobs in MediaRecorder and seeing that there was no
Blob::CreateEmptyBlob, nor an export of EmptyBlobImpl, I thought
Blob::CreateEmptyBlob would be the cleaner solution, so here it is.

This moves the impl of PushBlobRunnable from a runnable to MozPromise, which
let's us more easily modularize it's parts (gather the blob, fire dataavailable)
to make individual code paths more explicit.

This first of all does some refactoring of how metadata is encoded in
MediaEncoder. This is now guided by the new Muxer class. If we're ready to pass
data to the muxer and it does not have metadata yet, we provide metadata before
giving it any media data. This metadata is passed to the muxer in a single call.
The metadata provided in this call must stay valid for the entire recording.
This removes MediaEncoder::GetEncodedMetadata().
This also removes the ctor argument from the WebMWriter since it can now rely on
the single SetMetadata() instead.
To comply with the ContainerWriter::SetMetadata() docs,
WebMWriter::SetMetadata() will now also sanity check metadata.
ContainerWriter instances are updated somewhat, to accommodate these changes.
Lastly, and most important, the new Muxer class manages muxing of the (up to)
two tracks into a single container, ensuring that timestamps increase
monotonically throughout a recording.

Update MediaEncoder to pass frames to the muxer in order of their time stamps.
This should prevent the currently possible scenario where audio and video
frames are written with non-monotonically increasing timestamps (in violation
of the webm spec).

MediaQueue provides a better interface for interleaving frames when writing to
the muxer (this change will follow in another changeset). The queue interface
provides a nicer abstraction than manually managing a nsTArray.

This changes EncodedFrame to behave more like MediaData, so that EncodedFrame
can be used with the MediaQueue data structure. It also provides a somewhat
more consistent interface across media data types.

Move the responsibility of adjusting opus frame timestamps to the MediaEncoder.
This was previously done by the EbmlComposer, but doing so in the MediaEncoder
means we can have greater control over handling of time codes and interleaving
of frames.

Remove EncodedFrameContainer and clean up areas where it was used.
EncodedFrameContainer provided a wrapper around an
nsTArray<RefPtr<EncodedFrame>>, but it simplifies the code to simply expose
this array. Also clean up unused enums in EncodedFrame, and clean up some of
the outdated comments for our encoded frame handling.

Separating the encode and mux steps allows for better control over interleaving
audio and video data. If encode and mux are done in a single step it's possible
to mux large amounts of audio or video data which should have been interleaved
with the other data type to give correctly ordered time stamps in the target
container.

This is a potential fix that I thought it was worth doing rather than
implementing Blink's platform-dependent silliness. This ensures that the display
frame always has enough space to display itself.
Note that it may still get clipped, if there's no room for both the display
frame and the button.

When rendering text in webrender we rasterize glyphs either in local
space at a chosen raster scale, or in device space taking in to
account to text's transform.
We are not able to rasterize glyphs larger than a certain size,
however. So if the device-space font size exceeds this limit, then
currently we force the glyph to be rasterized in local space, at the
untransformed font size. This must then be scaled by the shader when
rendering text, and at high zoom levels this will result in blurry
text.
This change makes it so that rather than rasterizing at the
untransformed font size we rasterize at the font size limit. This will
mean the glyphs are rasterized at a larger size and will therefore
require less scaling, meaning they will appear less blurry.
