Define new player types to describe the two types of AudioPlayer
in OpenSL ES: those with a buffer queue source, those that
play from a given URI or FD.
Add a warning in the interface description of AudioService
that changes should be reflected in the native interface too.
Test: make, NDK tests to follow

AudioService keeps track of status of implementations of PlayerBase.
AudioService's PlaybackActivityMonitor maintains a list of
playback configurations for each PlayerBase, and a list
of clients that want to receive updates about the playback.
Playback activity clients can query the playback configuration
of the system through AudioManager, or register a callback
for updates. For clients with MODIFY_AUDIO_ROUTING permission
(system), the playback configurations contain more information
about each player (player type, uid, pid, state), and can see
all players, not just the "active" ones. The act of stripping
off data about the players that is not supposed to be seen
by non-system clients, is referred to as "anonymization". It
is implemented in system server, so no system data is ever
sent to playback activity clients without system permission.
More information about the AudioPlaybackConfiguration is
available in the SystemApi (uid, pid, player type, player state).

This is part of weaning apps off accessing system identifiers via
system properties API. Apps should use android.os.Build API instead.

Test: Enable MTP mode then check that mtp-detect output same as before this commit

Functionfs requires MtpServer to write descriptors before the device can be
configured. This adds a new configure call that will occur only when
functions are changed (new argument added to updateUsbStateBroadcast for this)
and be called after sys.usb.config is changed but before the waitForState
call to ensure compatibility with configfs devices.

Test: Manual
The IFD entry has a 4-byte field COUNT. It is read as int type
and is used as array size by ExifInterface. If a crafted JPEG
file contains a negative value, a NegativeArraySizeException
occurs.
Test: passed ExifInterface CTS

Deprecate methods where stream types are not used for
volume control operations.
Add a warning in the logs about the use of stream
types to encourage migration to audio attributes.
Since STREAM_ACCESSIBILITY is added in O for the
volume of a11y audio, throw an exception when
trying to use it for playback.

VolumePolicy: define two a11y modes: 1/ legacy where
a11y volume aliases to media volume, 2/ a11y where
the a11y volume is independent from any other stream
type volume.
Refactor accessibility service listening to accomodate
communicating to the volume controller when the
a11y service is running.
Make accessibility stream alias conditional on a11y
service running. Reflect the behavior in the
volume controller.
Test: enable Talkback and verify logs in Vol controller

Modified the signature of the abstract volume methods so
it is clear at the subclass level whether the volume
command is for a mute or a volume control.
Changed the implementations in the subclasses
accordingly.
Removed appOps handling inside SoundPool and made it
inherit from PlayerBase.
Moved handling of the camera sound restriction from
SoundPool to PlayerBase.
Added support in SoundPool native implementation for
muting, as each player has its own volume.
Test: play a long file with SoundPool and enter DnD mode

To protect system stability, any Binder calls leaving the
system_server must carefully be performed using FLAG_ONEWAY (or
the 'oneway' verb in AIDL) which prevents the call from blocking
indefinitely on the remote process.
In this CL, the system_server uses the new Binder.setWarnOnBlocking()
method to enable detection by default for all remote Binder
interfaces. It can also use Binder.allowBlocking() to allow
blocking calls on certain remote interfaces that have been
determined to be safe.
This CL adds the 'oneway' verb to several interfaces and methods
where it should have been added, and marks a handful of system
ContentProviders as being safe to call into. Also, we assume that
any services obtained from ServiceManager are part of the core
OS, and are okay to make blocking calls to.
