Previously, we've used getSupportedHeights/Widths() to find the supported
resolution. However, the height/width can be over-reported when using these
APIs. For example, getSupportedWidths and getSupportedHeights can both return
3840, but the supported height when using 3840 as width is only 2160.

This makes the reading period advance early as expected at the end of an ad
period. Before this change the reading position of the metadata renderer
prevented advancing the period until metadata arrived after the start position of
the following period. Only then the reading position of the metadata renderer
is updated and beyond the start position of the following period which is a
condition to advance the reading period.

Because transitioning to the next period is a virtual transition and the
SharedMediaPeriod keeps reading from the same underlying sample streams, the
metadata renderer can safely be ignored for this check.

We will be migrating our track selection UI components to be
based on TracksInfo. We need DownloadHelper to expose TracksInfo
to make it compatible with such components.

addTrackSelectionForSingleRenderer takes a list of legacy overrides,
which are then set on the supplied parameters one at a time to run
track selection. This allows multiple overrides for a single track
type to be applied in the download use case, despite it not being
possible to place such overrides directly into a single parameters.

For new style overrides, multiple overrides for the same track type
can be placed directly into a single parameters. Therefore we'll be
able to replace use of addTrackSelectionForSingleRenderer with use
of addTrackSelection, which is a much cleaner API. For this to work,
we need to make DownloadHelper apply multiple overrides in this case.

This will allow for easier customisation of the additional tasks
performed by the test runner, such as calculating metrics like SSIM.

These should have been removed as part of https://github.com/google/ExoPlayer/commit/1391b7c65dab1856dad363dff7c0a250245f1671, since we no
longer officially support overriding the layout file for this class.

This class is known as StyledPlayerView in exoplayer2.

DownloadHelper is in the ExoPlayer module, so there's no reason
why it can't use ExoPlayer specific track selections. That said,
we want our UI components to operate on generic
TrackSelectionParameters, and we want such UI components to be
useful for selecting tracks for download. To keep this interop,
it's necessary to have DownloadHelper accept generic
TrackSelectionParameters, or to require application code to
convert them. The first approach seems preferable!

This constructor always does the wrong thing for non-adaptive groups
containing more than 1 track, because it'll incorrectly generate an
adaptive selection. Replace it with a constructor for specifying a
single track within the group instead.

Only log GL exceptions in GlUtil if they aren't thrown. Otherwise,
it's up to the caller whether or not to log them to avoid logging them
twice.

Destroying the context destroys all of OpenGL (see
https://www.khronos.org/opengl/wiki/OpenGL_Context), so deleting
textures is redundant.

This test tests the same cases as the FrameEditorDataProcessingTest
as currently the main FrameEditor functionality is to apply a
transformation matrix using a TransformationFrameProcessor.

Test list can be structured so tests don't need to be in different

As evidenced by the somewhat awkward logic in PlayerControlView, the
previous design wasn't very friendly to expected usage. There will be
more usage when the track selection dialog components are migrated,
which would be similarly awkward without this change.

When a live stream is joined while ads are already playing, the LOADED event is
missed and we don't have ad information for those ads in the ad group that are
before the ad index at which we joined. This way we can clip the duration when we
receive the LOADED event for the last ad in the group. This fixes the problem of
the playback controls being hidden when content resumes after the ad group.

We use SSIM to measure the transcoding quality between. SSIM is a widely used
tool that compares the luma channel between two images, and generates a score
from 0 to 1 that indicates "how similar" the two images are.

In `SsimHelper`, we decode the two videos, extract matching frames and
calculates the mean SSIM (SSIM averaged all matching frames) for both videos.
Matching frames are referred to as "comparisonFrame" in the CL, which is
selected based on the frame number and a user-set comparison interval.
For instance, if the interval is 7, then every seventh frames are compared.

We use MediaCodec/MediaExtractor to decode the video, and use ImageReader to
extract the decoded frame.

The SSIM calculation logic is a inspired by and modified from the CTS
[MSSIMMatcher](https://cs.android.com/android/platform/superproject/+/master:cts/tests/tests/uirendering/src/android/uirendering/cts/bitmapcomparers/MSSIMComparer.java;l=1?q=mssimcom)
that has some errors and extra features we don't need (like handling RGB
images).

Adds TranscodeQualityTest to ensure high quality transcoding.

The AsyncronousMediaCodecAdapter should call MediaCodec.start()
on the same thread it calls MediaCodec.flush(), i.e. the playback
thread. This change removes the experimental flag that allowed
calling MediaCodec.start() from the callback thread.

The flag was flipped to true already.
