SDK / exoplayer

One goal we forgot about a little bit was to allow applications
to provide their own index implementation. This requires the
writable side to also be defined by an interface.

ImaAdsLoader gets the player position after the app releases
the player to support resuming ads at their current position
if the same ads loader is reused.

ShadowLooper -> ShadowLegacyLooper
ShadowRealisticLooper -> ShadowPausedLooper
ShadowBaseLooper -> ShadowLooper

And all public methods from ShadowLegacyLooper get pushed up to ShadowLooper

Copybara: OK

Also adjust Google3 tests  using custom looper shadows where necessary.
Convert exoplayer to paused looper to eliminate reliance on custom shadows

We currently do manual position tracking while the player is in error mode.
This is to allow an initial seek to the new position when trying to re-prepare.

Instead, we can just use our player.retry method and remove the tracking code.

PiperOrigin-RevId: 243819580

The removed condition only applies when prepare fails and no timeline was or
is known. We should keep a pending seek position in such a case. The internal
player does the same thing already.

- It can work with any DownloadIndex
- Also simplify things to not require that it's registered
  as a DownloadManager listener by someone else

- Expose constructors that take DatabaseProvider. Deprecate those
  that do not.
- Expose Cache.getUid. This will likely be used for naming of the
  tables accessed by DefaultDownloadIndex .

- Allows enforcing immutability, which in a future CL will allow
  avoiding allocating a new array/list on every call.
- Also some left over doc cleanup from the DownloadState rename.

The old domain automatically forwards to the new one. For consistency, change
all doc and code references regardless.

Also adds GitHub CNAME config file which configures our page for the custom
domain.

handleSourceInfoRefreshed checks for various conditions which may trigger a
change in position. In all cases, we need to resolve the new position for ads,
and if the corresponding MediaPeriods already exist, perform the seek to the new
position.

This change simplified the code by
 1. Moving all conditions in a single if-else structure which just determines
    the new playback position. This makes it easier to read and to follow.
 2. Doing the subsequent seek and position update in one final step to remove
    duplicated code.

As a side effect, it also improves some edge cases. For example when skipping
an ad to an already prebuffered period, we now properly update the existing
prebuffered period.

- Make a best effort to avoid posting MSG_DOWNLOAD_THREAD_STOPPED
  if the internal thread has already quit. Doing so is harmless,
  but causes an error in Logcat. We used to generate this warning
  quite a bit in ExoPlayerImplInternal as well, and we got quite
  a few issues filed about it, so best to avoid it if possible.
- Null out the back reference DownloadThread holds to its manager
  on release. This avoids a potential issue where a download thread
  can prevent GC of its manager if it doesn't cancel quickly.
  There's similar logic (with a similar comment) in Loader.LoadTask.

- Rename getAllDownloads to getCurrentDownloads to make it clear
  that it doesn't include completed and failed downloads
- Change getDownloadCount to isWaitingForRequirements, which is
  what it's used for. Added TODO to make it returns the right thing

If the returned retry delay is unset, we should use a DONT_RETRY_FATAL action
instead and dispatch the event with the "canceled" flag.

Non-trivial download state transitions are currently split across
DownloadManager and Download. These transitions are part of the
same state machine, so it's clearer if they're all in the same place
(i.e. DownloadManager, since this is the component that transitions
downloads between states).

PiperOrigin-RevId: 243249915

The only state DownloadInternal holds is duplicate of state contained
in Download, but can confusingly be temporarily out of sync. This is
error prone because it's easy to use the wrong variable (e.g.
download.state vs state). DownloadInternals methods are called into
and call out into DownloadManager, which makes some code paths that
are quite hard to follow.

It's possible to simplify DownloadManager quite a lot by removing the
duplicated state in DownloadInternal, at which point DownloadInternal's
methods flatten into DownloadManager, which can just hold an internal
list of Downloads directly.

This is a first step, which makes it clear that DownloadThready only
needs its immutable DownloadAction + an isRemove flag.

Put methods into a more sensible order (the same order as
in the switch statement, which is a more natural order with
e.g. initialize coming first and release coming last).

- Changed startDownloads/stopDownloads back to their previous behavior
  of starting and stopping all downloads at the manager level.
- Made setManualStopReason methods for the new case of setting a manual
  stop reason or some or all downloads.
- Added plumbing to specify an initial manual stop reason when adding a
  new download, without also overwriting the manual stop reasons of all
  other preexisting downloads. Using the value is left as a TODO pending
  a bit of further cleanup that'll make it easier.

- Remove completed downloads from progress notification.
- Treat restarting as a downloading, When there are both
remove and download tasks ongoing, we prefer to show a
download notification to a remove one. A restarting task
encapsulates is basically a (remove+download) task. Given
our preference, we should treat it as a download rather
than as a removal.

Both manifest loads currently use the default retry delay although a
LoadErrorHandlingPolicy is provided to the MediaSource.
