Default music volume is changed from 3/4 of max to 1/3 of max to
reduce initial volume over headphones percieved as too agressive.
Also add a property ro.config.media_vol_default to modify this
default value.
Bug: 62608451
Test: verify default music volume over headphones after factory reset.

This is becoming a common pattern (keeping track of which processes
are cached and not allowing them to do stuff in that state), so I
am turning this in to a general mechanism for monitoring this state
through the activity manager's IUidObserver. Now we can just have
AudoService implement its own IUidObserver to get this state and
update which uids it is blocking.
This required making some changes to uid change reports so that
the integer is now a bit mask instead of an enumerations, but that
is what it was already turning in to anyway. (This gets rid of
the crazy GONE_IDLE constant that we'd needed to add before because
it wasn't a bit mask).
Eventually the power manager should be changed to be told about
these changes to cached state instead of listening to every proc
state change, but we'll do that later, it is more disruption than
I want to take for now. However, while working on this, I noticed
that the power manager had regressed in the cached uids it would
actually block, because the activity manager was no longer telling
it about all uids that are idle. (I think this happened when I had
to change the default idle state of UidRecord to true.) So I am
adding a bit of new code to keep track of what idle state we last
reported to observers, to make sure we tell it about newly created
uids that are idle but have never actually become active.

Internal API, available through AudioManagerInternal, to flag
a UID as having lost the ability to play audio. When that
happens, all players associated with this UID are paused, and
future players are immediately paused when they report they
started.
Users of this API must "enable" a previously banned UID when
it is no longer in use.
Test: upcoming manual test with background apps

Limitation: When two apps make sound simultaneously while one uses a BT
route and the other uses the default route, switching activities between
the two different apps will not change the BT A2DP status until one of
the apps changes its playback status to inactive.

Add support for a system component to listen to recording activity
and know the uid and package name of the client app performing
the recording. This information is discarded for non-system
listeners on the server side.
Add log friendly dump for RecordActivityMonitor, AudioFormat and

When entering Total silence mode, text prompts from a11y were losing
AppOpsManager.OP_PLAY_AUDIO, causing them to play muted (amplification
of 0.0f) even though the STREAM_ACCESSIBILITY volume was not.
The fix consists in adding another category of sound suppression
behavior in AudioAttributes, for usage types that should never be
suppressed (== muted), and using it for USAGE_ACCESSIBILITY.
When ZenModeHelper iterates over usages to mute/unmute players,
consider whether that usage's suppression behavior is SUPPRESSIBLE_NEVER.
Test: turn Talkback on, then enter Total silence and verify Talkback is heard

Although the DATETIME and DATETIME_ORIGINAL tags are for different
purposes, the DATETIME value is set to the same value as
DATETIME_ORIGINAL tag's when loading the attributes of an image.
This CL prevents the problem by setting the value of DATETIME tag only
