It's OK to reveal that a screenshot has been taken, but the public
version of this notification no longer shows the actual screenshot
image itself (in case it was taken before the device was locked
and therefore might contain sensitive information).

In this implementation, DISABLE_NOTIFICATION_TICKER (which was never
really used on its own and can be safely subsumed by
DISABLE_NOTIFICATION_ICONS) is now DISABLE_PRIVATE_NOTIFICATIONS;
when this SystemUI bit is set by the keyguard, SystemUI knows to switch
its presentation into "public" mode, in which
VISIBILITY_PRIVATE notifications are replaced with their
publicVersion's contentView (or a placeholder view,
synthesized by SystemUI, that leaks no additional
information about the notification). VISIBILITY_SECRET
notifications are suppressed altogether in this mode.
This behavior is enabled but not activated by default. To
turn it on, run:
$ adb shell settings put secure lock_screen_allow_notifications 1
and restart SystemUI.

The new visibility property allows an application to signal
to SystemUI whether a notification's contents are safe to
show in "public" situations, i.e. outside of a secure
lockscreen, or whether they should be treated as "private"
(where only the icon is revealed).
Apps that post information that includes no personal or
sensitive information (e.g. a weather alert) can use
VISIBILITY_PUBLIC to allow users to see (and potentially
even dismiss) this kind of notification without unlocking
their devices.
The historical treatment of Android notifications
corresponds to VISIBILITY_PRIVATE, which is the default
visibility setting for all notifications, including apps
that are not aware of this API.
VISIBILITY_PRIVATE notifications may optionally specify a
publicVersion, which is a whole other Notification object
whose contentView will be shown in public contexts. This
allows an app to provide a "redacted" public version of its
notification that is more useful than the system-supplied
version (showing just the icon and app name) but still
conceals private information. For example, a messaging app
that today posts a Notification including the sender and
contents of each message could additionally specify a
publicVersion that says, simply, "N new messages".
There's also VISIBILITY_SECRET for notifications that should
be totally concealed (that is, no icon) in public contexts.
To reveal any hint of this kind of notification would
require the user to unlock the device.

While implementing the new TTS API, I found out that it's very difficult
to create an SynthesisRequestV2 instance for testing purposes - it's
a final class, with no publicly visible constructors.

This change allows TTS clients to create (and use) classes derived from the
UtteranceId class. This allows to attach a custom data and methods that
can be reached later in callbacks that take the UtteranceId instance as
parameter.
Also, since we can't depend on the identityHashCode results being unique,
this change adds AtomicInteger to generate unique identifiers for UtteranceId
instances.

IsContainedVolume -> hasIsolatedZVolume conveys that this affects Z
ordering of views
ProjectToContainedBackground -> ProjectBackwards, since it ended up
using its own projection target, separate from the 3d volume bit
