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.

Sometimes USER_UNLOCKED can be sent before USER_STARTED. This puts
lockdown in a bad state as it needs a fully-functioning user to tie
itself to and listen for connectivity events.

Layoutlib only disposes the bitmap and doesn't recycle them. This causes
a double deallocation that triggers an assertion.
This change makes Bitmaps to be only freed when the finalizer is called.

File extensions contain more information to determine mime type than MTP
format codes. The CL lets MtpDocumentsProvider return mime type from
file extensions if it's not inconsitent with format code.

In certain conditions, the first tap in a double tap could be detected
as Touch Exploration. This ensures that cannot occur.

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.
