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.

Allow APKs not in downloads to go directly to pakcage
manager via VIEW intent.
Add test coverage for retry dialog.

Sometimes providers may refuse to do a provider-side copy/move
even though the documents had the SUPPORTS_COPY/MOVE flags set.
This is because optimized copy/move may be only supported within
the same root.
Since there is no easy way to check if documents are on the same
roots from DocumentsUI, as well as whether the provider can actually
copy/move efficiently between different roots, we should tolerate the
failure and do a fallback to byte-by-byte operation.

This CL replaces List<String> with String[], which prevents from
calling get() and set() multiple times within a loop, in favor of
System.arraycopy().
Scanning a directory with 10K files went down from 1200ms to 450ms.

Basically push them through downloads.ui TrampolineActivity
to get origin url and referer and other security bits
added before handing off to package manager.

For instrumentation test apks, it should not statically include
Java libraries that are already present in the app module being
instrumented. They only need to be on classpath during compile
time.
