Add APIs for apps to query their cache usage compared to their
currently allocated quota. Since an app's private storage may live
on a different storage volume than the primary shared/external
storage, offer APIs to retrieve those values separately.
Add APIs to control two new cache purging behaviors:
-- setCacheBehaviorAtomic() which causes a marked directory and its
contents to be treated as an atomic unit.
-- setCacheBehaviorTombstone() which causes the OS to truncate
files instead of deleting them.

Now that installd has the implementation details we need, we can wire
up the public APIs to use them.
Shuffle APIs around a bit so that StorageStats can be reused for both
UID and UserHandle results, and rename StorageSummary to
ExternalStorageStats. Provide getTotalBytes() and getFreeBytes() as
first-class methods so we can answer those questions quickly without
paying the cost of measuring external storage details.
Current costs on a typical device with a test account after flushing
dentry caches:
queryStatsForUid() manual: 6922ms
queryStatsForUid() quota: 525ms
queryStatsForUser() manual: 1686ms
queryStatsForUser() quota: 113ms
queryExternalStatsForUser() manual: 42ms
queryExternalStatsForUser() quota: 2ms
For verification purposes, a new "fw.verify_storage" system property
can be set to compute both manual and quota statistics, and log any
discrepancies.

This API is designed to provide both UID-level stats and overall
summary data for a given storage device, as identified by UUID.
The use of UID-level granularity might appear a bit clunky, but it
matches other usage statistics (such as network and battery), and it
allows us to implement it using an extremely fast quota kernel
feature.
A future CL will wire up the implementation to installd.

Don't use the parole state to deal with the plugged-in trigger.
Otherwise standby apps will only be paroled for a few minutes

Apps making calls into the system server may end up persisting
internal state or making security decisions based on the perceived
success or failure of a call, or the default values returned.
The reality is that if the system process just died, init will be
along shortly to kill all running apps, so we should have no problem
rethrowing the RemoteException as a RuntimeException.

Calling into TelephonyManager each of hundreds of apps to check
if the app is carrier privileged was very expensive, especially
when there aren't even any carrier access rules specified. This
change fetches all the carrier privileged apps in one call,
reducing the number of IPC calls to the radio process and checks
the package names locally.
If the carrier rules change or packages are modified, the list
will be computed and fetched again.
Other optimizations in Telephony help speed up the individual calls
to check if a package is privileged, as well.

App Idle queries are very frequent and so they only check in memory stats.
However, in memory stats can be missing some entries, especially after a rollover, but also
due to a larger bug fixed in master (too risky to take now).
The fix is to do a deep query (reading older files from disk) and maintain a parallel cache
of stats for app idle. That way the rolling window of data required to serve app idle queries
stays in memory.
