    • Set BROWSER_SERVICE_EXTRAS_KEY_SEARCH_SUPPORTED automatically · 4c9ca8fa 
      This root extra needs to be set by apps manually in media1 and we
can do that automatically in Media3 based on the available session
commands.

    • Use MediaBrowserCompat.rootHints as connections hints · 21022c77 
      In Media3 there is the useful concept of connection hints that a
client can set when building the session and that are sent to the
service and passed to the `Callback.onConnect()` method when the
browser connects.

These connection hints are then included in the `ControllerInfo`
object that later will be passed to every callback method and the
implementor can then take decisions specific to these connection
hints.

These connection hints are not available in media1. However, when
an app creates a `MediaBrowserCompat` object, the constructor takes
a rootHint object that is sent to
`MediaBrowserServiceCompat.onGetRoot()`.

This change uses the browser rootHints as the connection hints when
creating the `ControllerInfo` for legacy browsers and makes them
available to the `MediaLibrarySession.Callback` domain methods in
the same way as connection hints of a Media3 browser.

    • Make adding ad live breaks more robust · 64e9e888 
      This change makes adding ad events in live streams more robust by allowing ad
groups to grow in number of ads if more ad events are received than initially
announced by the SDK.

With the IMA prefetch feature, an AdPod can grow in size in certain conditions
like from initially 2 ads to 4 ads being part of the ad group. With this change,
if an additional ad event arrives while the ad group is still being played,
the ad group is expanded. If the event arrives late and the ad group is already
completed, a new group is created for the remaining ads.

This also covers the case where we join the live stream while an ad is being
played and we missed at least one LOADED event from the SDK. Ads of the group
before the first LOADED event are ignored in such a case.

    • Fix `Cea608Decoder` handling of service switch commands in field 2 · 8c0f7827 
      From ANSI-CTA-608-E R-2014 section 8.4:
> When closed captioning is used on line 21, field 2, it shall conform
> to all of the applicable specifications and recommended practices as
> defined for field 1 services with the following differences:
> 1. The non-printing character of the miscellaneous control-character
>    pairs that fall in the range of 0x14, 0x20 to 0x14, 0x2F in field 1,
>    shall be replaced with 0x15, 0x20 to 0x15, 0x2F when used in field
>    2.
> 2. The non-printing character of the miscellaneous control-character
>    pairs that fall in the range of 0x1C, 0x20 to 0x1C, 0x2F in field
>    1, shall be replaced with 0x1D, 0x20 to 0x1D, 0x2F when used in
>    field 2.

This basically means that `cc1=0x15` in field 2 should be interpreted as
`cc1=0x14` in field 1, and same for `0x1D -> 0x1C`.

The `isMiscCode`  method above already handles this by ignoring the LSB
(the only difference between `0x14` and `0x15`, and `0x1C` and `0x1D`)
by AND-ing with `0xF6` instead of `0xF7`. This change uses the same
trick in `isServiceSwitchCommand`.

    • Use int for an unsigned byte value in Cea608Decoder · c9a0aa9d 
      This is a no-op, but it's more 'correct' because it avoids any potential
sign mix-ups that come from storing an unsigned byte (with a
potentially set MSB) in a signed java byte variable.

    • Add CanIgnoreReturnValue to AudioProcessor#configure + implementations · 8723e74b 
      Although it can be useful to check the output format, it's not required or needed.

For some AudioProcessor implementations, it is stated/obvious that
the output format will match the input, in which case there is no
a need to check the return value.
