These have the same value (`-1`), and basically the same meaning (offset
in an array/list/file/byte stream/etc), but 'position' is an overloaded
term in a media playback library, and there's a risk people assume that
methods like `Player.getCurrentPosition()` may return
`C.POSITION_UNSET`, when in fact unset media times (whether duration or
position) are always represented by `C.TIME_UNSET` which is a) a `long`
(not `int`) and b) a different underlying value. (aside:
`getCurrentPosition()` never returns an unset value, but it's a good
example of the ambiguity of the word 'position' between 'byte offset'
and 'media timestamp'.)

The callback is currently triggered on the ExoPlayer playback thread
instead of the app thread that added the listener.

PiperOrigin-RevId: 492474405

This inconsistency was exposed by an upcoming change to deprecate
`POSITION_UNSET` in favour of `INDEX_UNSET` because position is an
ambiguous term between 'byte offset' and 'media position', as shown
here.

This is necessary to move video decoding to the AssetLoader. Otherwise,
if the decoder max pending frame count is reached, the AssetLoader will
stop queuing frames to the pipeline, and process data will not be called
anymore.

In some cases we split a test method, and in other cases we just add
line breaks to make the separation between arrange/act/assert more
clear.

This adds the forwarding logic for most setters in SimpleExoPlayer
in the same style as the existing logic for setPlayWhenReady.

This change doesn't implement the setters for modifying media items,
seeking and releasing yet as they require additional handling that
goes beyond the repeated implementation pattern in this change.

EncoderUtil using a static list to cache encoders means it's not possible to
use a different set of encoders for different tests when running all
robolectric tests together.

This better matches the terminology we use elsewhere in the Player
interface, where items inside the playlist are referred to as
"media item" and only the entire list is called "playlist".

Bypass Z Fold 4 HDR10 tone-mapping bug by limiting the max frame count to 12.

This passed with a value of 14, and failed with a value of 15, but I figured I'd use 12 just to be safe.

To support OPUS offload, we need to provide a few configuration values

OPUS offload.

The list of charsets is already hard-coded, and using `Charset` types
ensures they will all be present at run-time, hence we will never
encounter an 'unsupported' charset.

FakeClock keeps an internal list of messages to be executed to
ensure deterministic serialization. The next message from the list
is triggered by a separate helper message sent to the real Handler.
However, if the target HandlerThread is no longer alive (e.g. when
it quit itself during the message execution), this helper
message is never executed and the entire message execution chain
is stuck forever.

This can be solved by checking the return values of Hander.post or
Handler.sendMessage, which are false if the message won't be
delivered. If the messages are not delivered, we can unblock the
chain by marking the message as complete and triggering the next
one.

Remove self-links, and remove section that is documenting internal
ordering behaviour of
[`SimpleBasePlayer.getCombinedMediaMetadata`](https://github.com/google/ExoPlayer/blob/bb270c62cf2f7a1570fe22f87bb348a2d5e94dcf/library/common/src/main/java/com/google/android/exoplayer2/SimpleBasePlayer.java#L1770)
rather than anything specifically about this method.

This is more clear than using Format.NO_VALUE, when we do actually intend for an
output value.

Also, fix @see formatting by using summary fragments instead, and add an error
output for OETF and EOTF transfer functions.
