This moves TestUtil#runMainLooperUntil and
TestUtil#createRobolectricConditionVariable to a new RobolectricUtil
class.

Also move testutil classes that use Robolectric-related utils classes
(e.g. TestPlayerRunHelper, TestDownloadManagerListener).

1. The first time the player controls are are made visible,
   there is no animation.
2. The first time the player controls are made visible, the
   "select tracks" button isn't displayed. When tapping to
   subsequently hide the player controls, the button briefly
   becomes visible and then is hidden again. This bug is due
   to state in StyledPlayerControlViewLayoutManager being
   out of sync, resulting in StyledPlayerControlView's
   onVisibilityChange not being called properly.

After this change both of these issues should be resolved.

We stopped using using this MIME type in
https://github.com/google/ExoPlayer/commit/74a9d8f680995f2096c59fde6cd1ef6e85bb4d55

This broke subtitle decoding in some cases (Issue: #7985), which I
fixed in
https://github.com/google/ExoPlayer/commit/7b8895d655c9b48e042f66045bc9c7ab27e93346.

After some discussion we've decided SubtitleDecoderFactory shouldn't
depend on Format.containerMimeType (since the samples have already been
extracted by this point, so the container shouldn't matter). So this
change fixes DashManifestParser to use MimeTypes.APPLICATION_MP4VTT (and
reverts the no-longer-needed SubtitleDecoderFactory change).

TestExoPlayerBuilder can be used from both emulator and robolectric
tests, TestPlayerRunHelper uses Robolectric Looper behaviour, meaning
it can be moved to the robolectricutils module in a follow-up change.

Adjusted the bottom layout of StyledPlayerControlView :
- Enlarged bottom button's height to make tapping easier.
- Extended greyed background area to upper edge of seekbar.
- Gave padding between bottom edge of the overall layout and bottom buttons.
- Reduced horizontal margins between bottom buttons.

Previously, the overflow button was always shown at the bottom in StyledPlayerControlView
and hided the settings cog even when there is enough space.

With this change, the settings cog moves out from overflow and
the overflow button is shown only when the buttom space is not enough.

Experiments showed the timeout is beneficial to avoid ANRs and
we can thus enable the feature by default.

Also add configuration to set the timeout if required.

Using a timeout prevents ANRs in cases where the underlying platform
gets blocked forever, so we enable this feature by default.

`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).

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`).
