There are two different patterns we use at the moment:
1. Call both deprecated and non-deprecated method from call site with
no default method implementation body.
2. Use default method of non-deprecated method to call deprecated
method.
Pattern 1 is easier to reason about as it makes the calls more explicit,
so changing all usages of pattern 2 to pattern 1.

This adds an optional DrmSessionManager#preacquireSession() method
and implements it on DefaultDrmSessionManager.
The manager doesn't promise to keep the preacquired sessions alive, and
will proactively release them if a ResourceBusyException suggests the
device is running out of available sessions in the underlying framework.
In a future change, SampleQueue will preacquire sessions on the loading
thread and keep track of preacquired 'references', releasing them
when seeking or clearing the queue.

We already report these errors through callbacks to interested listeners.
However, to ease debugging with bugreports and local error detection,
it's helpful to also log these non-fatal execptions to logcat. Otherwise
nothing in logcat indicates that the player recovered from an exception.

This is preferable to just logging to LogCat so that listeners can
report this to analytics systems if required.

The SampleStream.readData contract is that when reading a sample
with a flags-only buffer, the buffer timestamp and flags should
be set and the read position should not be advanced.

This type is different to the selection reason, which is
dynamic (i.e., corresponds to the individual selected track,
which can change during playback). The static type is
exposed via TrackSelection, where-as the selection reason
will be internal to the core (i.e., player) module.

These have limited value, and are confusing because they're only
actually used if the override only selects a single track (if the
override is an adaptive selection then the values are never used).
The simpliest path forward is to remove them.

It allows Bundleable classes throw a RuntimeException which is broader
than IAE. Now, Bundleable implementation may utilize checkNotNull for
brevity.

The source can be used in compositions (in fact, every source is
automatically used in an internal composition when constructing the
playlist), and there is not really a concept of top-level media source
any more since the Player supports playlists.
The actual restriction is that the content media source needs to have
exactly one period to be able to create a SinglePeriodAdTimeline.

The previous logic was changed under the assumption that the first box
inside a meta box was not always an hdlr box, but this is not true.

The available end time was accidentally substracted by the start time
of the last period.
To avoid similar time reference confusion in the future, also renaming
many variables and methods to clearly reflect the time reference point.
And to avoid constant conversion, the processManifest method also
attempts to converge to time relative to the start of the window as
quickly as possible.

If keepalive is disabled the existing code over-eagerly releases
DrmSession instances. This is arguably OK since a (Default)DrmSession
should be released before its (Default)Manager is released
(since the underlying MediaDrm instance might be released when the
manager is released). And if all sessions are released before the
manager is released then `sessions` is empty, so the loop is a no-op.

The `DrmConfiguration.sessionForClearTypes` property is often used
to ensure a secure decoder is used for clear ads played in encrypted
content. This is because some devices show black frames when switching
decoders.
Before this change the DRM config isn't propagated down when
constructing the ad media source, meaning
`DrmSessionManager.DRM_UNSUPPORTED` is always used, which will
cause playback to switch from secure to clear decoder when transitioning
to an ad break (ignoring the MediaItem `sessionForClearTypes` option.

Without this a new manager is instantiated for every item in a playlist,
meaning the impact of caching improvements to DefaultDrmSessionManager
are reduced (since the cache doesn't persist across playlist items).
With this change, playlists of items with identical DRM config will use
the same manager instance (and thus share existing sessions).

ControlDispatcher and DefaultControlDispatcher also need
to move to common for the UI module. As does PlaybackPreparer,
although that will be removed entirely in a future release.

Also allow the player's prepared ad media period durations array to exceed the
length of the loaded ad URIs array, as it's possible for the player to buffer
an ad media period fully at the point where it's known that an ad is coming up
but its URI is still unknown.

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.
