When the ServerThread handles ACTION_SHUTDOWN intent it sometimes get
stuck on mStatsLock in NetworkStatsService.java.

2 android.os.Handler.handleCallback()
3 android.os.Handler.dispatchMessage()
4 android.os.Looper.loop()
5 com.android.server.ServerThread.run()
This happens when the NetworkStats thread is already holding the
mStatsLock while updating NTP.

Since the NTP update consists of several socket operations it may get
stuck long enough to trigger a System Server Watchdog even though the
socket timeout is set to 20 second.
Further, the NTP update doesn't actually need to be performed inside
the locks and an attempt to change this was made earlier, but the code
wasn't actually moved outside the locks.

When a user is removed, migrate all network stats belonging to that
user into special UID_REMOVED bucket. Also removes those stats from
kernel to avoid double-counting if another user is created.

You can now use ALL and CURRENT when sending broadcasts, to specify
where the broadcast goes.
Sticky broadcasts are now correctly separated per user, and registered
receivers are filtered based on the requested target user.
New Context APIs for more kinds of sending broadcasts as users.
Updating a bunch of system code that sends broadcasts to explicitly
specify which user the broadcast goes to.
Made a single version of the code for interpreting the requested
target user ID that all entries to activity manager (start activity,
send broadcast, start service) use.

Currently, the client requests tracked in mClientIds for resolution
requests isn't cleared at all and causes failues of additional registration
and discovery requests once the number of requests reaches MAX_LIMIT. In
addition, bubble up unhandled native events to default state of nsd state
machine.

Make StateMachine#quit non-conditional and remove the need to
process the SM_QUIT_CMD it is now private.
Rename halting to onHalting.
Add onQuitting
Change the message specific logging to be more generic and change
the xxxProcessedMessagesYyy methods to xxxLogRecXyy names. Also add
addLogRec(String) and addLogRec(String, State) as the generic logging
methods.

We had a gap in sync coverage between doing a check and waiting and a
matching gap between setting a condition and notifying. It was possible
to get context switched just so and have the notify hit before the waiter
had started waiting.

Remove some logging from NDC so it's local log is more useful.

When XT stats are available, transition to prefer them over DEV,
since they aren't subject to hardware driver bugs. Only switches at
the first atomic XT bucket, and adds a Settings.Secure flag to force
back to DEV if needed. Includes tests to cover transition.
Fix tests where device overlay would change which network types
reflected data usage. Test both history and summary APIs. Fixed
collection timestamps to reflect full buckets.

In rewriteSingle(), catch Throwable to rollback to backup file,
instead of just IOException. Also add dumpAll() to pack up contents
for later debugging, and use it when encountering bad stats.

- Remove the notion of channel from an application perspective
- Remove the use of DnsSd as part of API and add a protocol type to allow
future extensions
- Use the listener object as a handler for stop and unregister operations. Also,
we now allow multiple active discovery operations.
- Remove init/deinit operations in favour of setting up construction

Default is 2MB persist threshold, but even that can be substantial
for devices on 100MB/month plans. This change gradually reduces the
persist threshold up to 8x lower (256kb outstanding) based on lowest
active policy.

Add method to parse new iface_stat_fmt proc stats, or return null
when kernel support is unavailable. Add test and remove older, unused
parsing code. Create new "xt" recorder to persist the new xtables
counters when available.
Add SSID support to NetworkIdentity to fix policy tests.

Previously we'd only handled quoted strings going into NDC. This
change auto-handles quoted strings in broadcasts and allows
protocol handlers to request de-quoted elements when needed instead
of using the generic split(" ").

Use xt_qtaguid iface_stat_all counters, which are monotonic during
a single boot.
Track all ifaces associated with mobile networks since boot, and
move TrafficStats to using these ifaces. This will include usage of
networks omitted from config_data_usage_network_types, specifically
on devices that recycle network interfaces across APNs.
Split wildcard template matching, and move NetworkStatsService to
use mobile wildcard when logging stats.
