When playing a playlist where the exact maximum input size is known from the
container for each item, it may be necessary to recreate the decoder to increase
its maximum input buffer size at the point of transitioning from one item to the
next, which can make transitions non-seamless.
Scale up the initial video decoder maximum input size so playlist item
transitions with small increases in maximum sample size don't require
reinitialization.

Add automatic audio focus handling to SimpleExoPlayer. Audio focus
handling is an opt-in feature that can be requested by passing
the system's AudioManager and an AudioFocusConfiguration to
SimpleExoPlayer.setAudioFocusConfiguration.
When audio focus is being managed by SimpleExoPlayer, the player
will transparently handle pausing playback during
AUDIOFOCUS_LOSS_TRANSIENT, as well as lowering playback volume
during AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK.

EventSampleStream.readData required eventStreamUpdatable to be
false for END_OF_STREAM to be returned, but it was only being
set to false when the manifest became static. This change also
sets it to false if the period is not the last one in a dynamic
manifest. It also renames it the parameter to appendable, since
that's what it really represents. Events may still be removed
from the start of the EventStream as the period starts moving

There is some risk associated with this change, as audio track buffers come from
shared memory and limits may be device-specific. I've tested these sizes on
Nvidia Shield TV and Nexus Player on various builds. The maximum size allocated
is about 800 KB. We could implement support for retrying creating the audio
track if it fails to initialize, but it seems preferable to avoid the extra
complexity required to do that unless we know it's necessary to work around
device-specific limitations.

After [] we support default font size for TTML, relative to the cellResolution of the document. However, this introduced a bug that makes TTML font-size in such case always follow the cellResolution font size, even when SubtitleView.setApplyEmbeddedStyles(false) and SubtitleView.setApplyEmbeddedFontSizes(false) were used.
This CL updates the fix so that the default font-size using cellResolution works in the same way as other embedded styles, and can be turned off using setters from SubtitleView.

Codec initialization may fail in creation, configuration or when start()ing the
codec. If codec initialization fails, there may be other codecs available that
could handle the same format, but currently ExoPlayer can only try to use the
first listed codec for the input format and gives up if it fails to initialize.
This change implements support for optionally falling back to alternative
decoders if initialization fails. MediaCodecSelector can now return a list of
decoders to try in priority order, and use the Format when choosing a codec.
With the default implementation, the codecs and order come from MediaCodecList,
and matches the order used internally by MediaCodec.createDecoderByType (which
implements the same kind of fallback though only to the creation step, without
configuring/starting the codec).
This feature is useful for apps that want to play several videos concurrently on
devices that have software decoders (like OMX.google.h264.decoder), as the new
behavior allows new codecs to be created when no hardware-accelerated decoders
are available.
The list of available codecs is queried when initializing the codec after a
format change that requires a new codec to be instantiated. When a decoder fails
to initialize it is removed from the list of available decoders and won't be
tried again until the next format change (or until the renderer is disabled).
Note: this change does not affect the renderer capabilities API, as when
checking format support we don't know which codec will be used.

When the player state is changed from an event listener callback, we may
get recursive listener notifications. These recursions can produce a wrong
order, skip or duplicate updates, and send different notifications to
different listeners.
This change serializes listener notifications by clustering all update data
in a helper data class and adding the updates to a queue which can be handled
in a loop on the outer layer of the recursion.
As playWhenReady updates also reference the current playbackInfo, we need to
redirect the listener notifcations for setPlayWhenReady to the same queue.
