We currently block the loading thread until the calculated load
time has past and then unblock again by a message sent from the
playback thread. However, because the loading thread itself is not
using a Looper and runs freely, we don't control when the short
calculations on the loader thread that determine how long we have
to wait are happening, and we also don't control how long it takes
to start and stop this thread.
To solve these problems and to make the playback deterministic we
can
1. Send a message on the playback thread to block until the loader
thread has started.
2. Block the playback thread whenever a loading thread is doing its
short calculation of wait times. The playback thread knows when it
can continue because loading either enter a new waiting state for
a simulated load time or loading is finished completely.
3. Also wait on the playback thread until the loader has shut down.
As this is waiting for a message on the playback thread, we can
achieve this by sending messages to ourselves at the current time
until the loader is shut down.
All 3 steps together ensure that the loading thread interaction is
compeltely deterministic when simulating bandwidth profiles with the
BandwidthProfileDataSource. As we need to notify the source before and
after the load started/finished, we also need a small wrapper for the
chunk source when running the playback.

- When throwing a recoverable error from a renderer, it's important to understand
exactly how the player will attempt recovery. Clarify the documentation to
make this explicit.
- Rename some methods/constants to make it clear that error recovery is specific
to renderer errors. The current recovery mechanism only makes sense for
renderer errors. Making the naming renderer specific avoids reader doubt that
the implementation doesn't appear to be generic enough for other types of
errors.

Before, the level was set to null in this case.
MediaCodecUtil.getCodecProfileAndLevel() was therefore returning null
and the fallback to AVC/HEVC was not enabled in MediaCodecVideoRenderer.

It's for classes to clearly denote they support bundling and it gives
us a good place to document the best practice to implement fromBundle.

In both cases it's deliberate that all excluded constants should use
the default branch. Furthermore, there are quite a lot of excluded
constants missing, so it's probably better to suppress the warning
than to include them all.

* Move cherrypicked changes from dev-v2 to 2.13.0
* Use a bulleted list instead of comma-separated.
* Standardise everything into present, imperative sentences.
* Remove a couple of mixed-font words (I left cases with a separating
apostrophe, as these seemed visually clearer).
* Merge multiple issue links into a single set of parentheses.

Main improvement is to switch away from ExoPlayerTestRunner and to
split out the waiting component so that the same class can be used
from Robolectric tests in the future.
The only functional difference is that that BufferLengthLogAction
is removed completely because the data isn't used downstream and the
method of collecting this data is a bit arbitrary.

Without this no error is currently logged or propagated to EventLogger.
The propagation doesn't happen because
MergingMediaSource.ForwardingEventListener only propagates events
originating from the "main" source in the merge:

We can dequeue as part of getting output buffers (or output buffer info) in
`MediaCodecAdapterWrapper`, which simplifies the caller slightly.
Also try to make minor clarifications in method naming in
`TransformerAudioRenderer`.

This also moves DefaultHttpDataSource to common, which seems
sensible, else non-player components that need a DataSource
don't have any useful concrete implementations. We should
think about moving some of the other concrete implementations
to common as well.

- Store output format in `MediaCodecAdapterWrapper` when we get a format from
the codec, instead of creating it on demand.
- Make format building code not audio-specific.
- Remove `MediaCodecAdapterWrapper.getConfigFormat` and instead keep track of
the input/output formats in the renderer. This will mean that the code still
works if an audio processor changes the audio format in future.
- Make exceptions thrown during audio rendering use the same (input) renderer
format.
- Misc other minor cleanup.
