Developers need to add FLAG_ACTIVITY_MULTIPLE_TASK flag if they don't
want an existing instance of their activity to be used.

There are a handful of core system services that collect data from
third-party ContentProviders by spinning them up and then caching the
results locally in memory. However, if those apps are killed due to
low-memory pressure, they lose that cached data and have to collect
it again from scratch. It's impossible for those apps to maintain a
correct cache when not running, since they'll miss out on Uri change
notifications.
To work around this, this change introducing a narrowly-scoped
caching mechanism that maps from Uris to Bundles. The cache is
isolated per-user and per-calling-package, and internally it's
optimized to keep the Uri notification flow as fast as possible.
Each Bundle is invalidated whenever a notification event for a Uri
key is sent, or when the package hosting the provider is changed.
This change also wires up DocumentsUI to use this new mechanism,
which improves cold-start performance from 3300ms to 1800ms. The
more DocumentsProviders a system has, the more pronounced this
benefit is. Use BOOT_COMPLETED to build the cache at boot.
Add more permission docs, send a missing extra in DATA_CLEARED
broadcast.

FLAG_LAYOUT_NO_LIMITS allows a window to extend its dimensions outside
the screen area by setting the display frame to a really big value.
We don't want this in multi-window mode since all window frames should
be limited to their parent task/stack dimensions.

We now wait until both the wallpaper imagery and the metadata have
been restored [if present], and then explicitly regenerate the crop
from the source based on that.

Use StorageManager APIs to get the encryption
state instead of from the system properties
directly.

When an APK is verifier during installation, the recently added
APK Signature Scheme v2 code uncondionally memory-maps the whole file.
This fails for very large APKs, even those which are not signed with
APK Signature Scheme, thus preventing installation of such APKs.
This temporary workaround pretends that the APK is not signed with
APK Signature Scheme v2 if the APK cannot be memory-mapped because
there's insufficient memory.
This workaround will be removed soon, once APK Signature Scheme v2
APK verification logic can handle very large APKs.

- When setting blanket user restrictions, per-package
exemptions may be granted.
- Exempt the current active VrListenerService from the

Previously we were using native config flags in some places that expected
Java flags, and vice-versa. All usages of config flags are now annotated
to ensure we're using the right type.
Cleans up annotations on most methods that were touched.
