`subtitle` is only guaranteed to be non-null if
`nextSubtitleEventIndex != C.INDEX_UNSET`. The null check added in
https://github.com/google/ExoPlayer/commit/0efec5f6c12a5d583f24c122fbcbc1b1eebbabc3
was too early.

This was broken by https://github.com/google/ExoPlayer/commit/74a9d8f680995f2096c59fde6cd1ef6e85bb4d55
because DashManifestParser switched to setting Format.sampleMimeType to
text/vtt while SubtitleDecoderFactory was still expecting
application/x-mp4-vtt. This change teaches SubtitleDecoderFactory to
check both Format.containerMimeType and Format.sampleMimeType.

I'll investigate a follow-up change to remove
MimeTypes.APPLICATION_MP4VTT completely (it's currently still used in
AtomParsers).

In the test, a real instance of SimpleExoplayer plays two identical Mp3 files.
The GaplessMp3Decoder will write randomized data to decoder output on receiving
input. The test compares the bytes written by the decoder with the bytes
received by the AudioTrack, to verify that the trimming of encoder delay/
padding is correctly carried out.

Test mp3 has delay 576 frames and padding 1404 frames. File generated from:
ffmpeg -f lavfi -i "sine=frequency=1000:duration=1" test.mp3

This change needs robolectric version 4.5, which is not currently released (2020 Sep 30).

This holds shared test infrastructure that needs to depend on
Robolectric.

When I moved ParsableByteArray#data behind a getter I replaced some
assignments with calls to reset(byte[]):
https://github.com/google/ExoPlayer/commit/ce2e6e2fd625db787b1f400614adcd7458144bbd

reset(byte[]) deliberately sets `limit` to `data.length`, in order to
handle cases that were reassigning `data` but not updating `limit`.
However OggPacket was already using `limit` to track where to write
'new' data into the array, so changing `limit` to `data.length` caused
us to try and write new data beyond the end of the array.

I looked at other uses of reset(byte[]) in https://github.com/google/ExoPlayer/commit/ce2e6e2fd625db787b1f400614adcd7458144bbd
and condluded the only other usage in MatroskaExtractor is legit and
shouldn't be updated like this (because MatroskaExtractor previously
*wasn't* correctly updating/maintaining `limit`).

Non-realtime AudioTrack playback speed was not taken into account when
extrapolating the old mode's position, causing the position not to
advance smoothly.

This should be a no-op when not using AudioTrack playback params for
speed adjustment.

Every other subtitleButton has an if not null check, but does not force non null.

On receiving a fetch error for an ad that would otherwise play based on an
initial/seek position, the pending content position wasn't cleared which meant
that position reporting was broken after a fetch error. Fix this by always
clearing the pending position (if there was a pending position that will have
triggered the fetch error).

Also deduplicate the code for handling empty ad groups (fetch errors)
and ad group load errors.

implementation.

Retry AudioTrack init and write for 100ms before
giving up and aborting playback.

This was tested by throwing every 2 init/write and
making sure playback did not stopped.

This issue has been observed on a test app stress
testing setEndOfStream.

The issue has not been observed on ExoPlayer,
probably due to timing differences, but it is fixed
preventively.

the same sample but just output to a different dump file.
