When the timeline becomes empty, the playback state transitions to "ended".
When the timeline becomes non-empty again, exceptions are thrown because MSG_DO_SOME_WORK is still regularly sent and media periods are getting prepared.
This change ensures that no MSG_DO_SOME_WORK messages are sent in "ended" state.

These changes are in part related to handling playback of mixed clear
and encrypted content, where we might want to use a secure decoder
throughout, but only have drm init data and only care about the state
of the DrmSession during playback of encrypted parts.
- requiresSecureDecoderComponent became unnecessary when we added
ExoMediaCrypto, which provides a layer in which requiresSecureDecoderComponent
can be overridden.
- Relaxed requirements for obtaining the MediaCrypto. It's helpful
to allow retrieval in the error state, since it can be used to
instantiate a decoder and play clear samples.
- Deferred throwing of errors in renderer implementations. As long as
we can get a MediaCrypto, we should init the codec. We can also
play clear samples without failing if playClearSamplesWithoutKeys is
true, regardless of the errors state.

This change allows you to enable/disable tracks within which
all samples are key-frames without any re-buffering (e.g. audio,
text and metadata). This effectively reverts V2 back to the
behavior in V1, only this time we're doing it properly. []ly
disabling/enabling, or disabling/enabling whilst paused, no longer
cause samples to get "lost" between the source and renderers.
Note it also becomes really easy to support a few other things,
although support is not exposed in this change:
- Enable/disable video tracks without any re-buffering, by
changing the toKeyframe argument passed to discardTo to true.
- Retain media in the buffer for some time after it's been played
(e.g. to support a single back-5s-seek efficiently), by
subtracting the desired back-buffer time from the value that's
passed to discardTo.

It's a bit messy at the moment with the deprecated methods
in there, but on the read side the new set of methods is as
follows:
Modifies the start of buffer:
- discardTo(time, keyframe, ...) [this is new]
- discardToRead()
- discardToEnd()
Modifies the read position:
- rewind()
- advanceTo(time, keyframe, ...) [this is a generalization of skipToKeyframeBefore]
- advanceToEnd() [previously called skipAll]
- read(...)
Which seems quite nice and self-consistent, and is powerful
enough for everything that we need to do as we move MediaSource
implementations over to the new methods.
TODOs for subsequent changes:
- Re-order methods in the two classes so that they're actually in
the same order, and move the deprecated ones out of the way
- Enhance SampleQueueTest to also cover new functionality, as we
start transitioning MediaSource implementations over to use it.

Previously, writeAllocationNode was not advanced to the
terminating node when finishing writing sample data that
fills exactly up to the end of the current write node.
This wasn't actually broken, but is confusing because it
causes edge cases where the start/read references could
temporarily refer the node after the current write node.
This change advances the write reference in this case,
removing this confusion and bringing the implementation
in line with what the design doc says happens.
Also making some simplification and consistency changes.

AbstractConcatenatedTimeline repeatly calls methods of its implementation to
query a specific child timeline. This may be inefficient if the implementation
repeatly executes the same code to find the timeline.
Changed the class such that it now queries all information at once using a meta
data class. As all methods need at least two of four variables anyway, this
doesn't generate unnecessary overhead.
Also generified the UID for the child indices to allow new implementations to
use some other UID besides the index.

Currently, media is discarded from DefaultTrackOutput
and SampleMetadataQueue as soon as it's been read. In
upcoming changes we'll decouple discard and read. This
will make it possible to retain already-read media in
these buffer classes, and allow the read position to
be moved backward as far as media is retained. This is
important for fixing an edge case around 608/EMSG
tracks, and could also underpin future features like
allowing retaining of X-seconds past media in the
buffer.
This change renames some variables and methods to
prepare for the upcoming changes. read/write indices
are renamed to start/end. The upcoming changes will
add a read index that's between the two. isEmpty is
inverted and renamed to hasNextSample, since it will
be possible to not have a next sample (because the
read index == end index) but for the buffer to not
be empty (because start index < read index).
