When an iface goes inactive, xt_qtaguid maintains historical counters
instead of discarding. Now reading and returning those values in
NetworkManagementService summary calls. Tests to verify stats are
returned.
Modify NetworkStats to include rxPackets and txPackets values, and
move to Entry to eventually hide internal storage details.

When someone tries to revoke packageA, it is possible that packageA is
already revoked by packageB. In this case packageB should not be revoked,
and the new prepare() can help solve this problem.

Both stats and policy make NMS calls that depend on bandwidth control
being enabled, so move enable/disable into NMS and drop calls when
disabled. This avoids throwing heavy ISE exceptions when disabled.
Only include recent data when writing NetworkStatsHistory as part of
dumpsys call. Introduce manual poll event for Settings UI.

Change NMS parsing to handle extended /proc/ stats formats by pairing
values with header keys. Move TrafficStats to integer tags to match
kernel internals, and offer well-known tags for system services.
Async policy event dispatch from NPMS, and update tests to block for
event dispatch. Narrow app policy to exclude apps signed with system
key, which are usually critical.

Complete rewrite of WifiWatchdogService.java. Checking for connectivity and managing wifi upon failure detection.

Now stores tags other than TAG_NONE (0x0), which are useful for app
debugging. Combine UID and tag together into single long key, and
expose tag data through AIDL when requested. Change NMS to track
TAG_NONE as total UID traffic, matching the kernel definition.
Added TAG_MAX_HISTORY to control how long tag-granularity statistics
are stored; overall UID usage is still kept for UID_MAX_HISTORY. Fix
bug to trim NetworkStatsHistory outside normal polling loops to catch
non-active networks and UIDs.
Test to verify UID and tag packing, and to verify that UID traffic on
two networks are combined to match MOBILE_ALL template.

When UID_REMOVED, clean up any existing UID network policy so it
doesn't linger for future apps. Also move any NetworkStatsHistory
to special UID_REMOVED tracking bucket.
Tests for new removal code. Also test detailed UID stats, including
network changes to verify template matching logic.

Teach NMS to read qtaguid stats from kernel, but fall back to older
stats when kernel doesn't support. Add "tags" to NetworkStats entries
to support qtaguid. To work around double-reporting bug, subtract
tagged stats from TAG_NONE entry.
Flesh out stronger NetworkTemplate. All NetworkStatsService requests
now require a template, and moved matching logic into template.
Record UID stats keyed on complete NetworkIdentitySet definition,
similar to how interface stats are stored. Since previous UID stats
didn't have iface breakdown, discard during file format upgrade.

Currently, kernel definition of metered networks is applied at the
interface level. This change maintain list of those metered ifaces
and notifies policy listeners, like ConnectivityService. (This gives
us a consistent picture of when a network would be blocked.)

If you do it before you have a race condition and some apps will
manage to reconnect on the dieing network before it goes and then

NetworkStats now grows in place with arraycopy() instead of callers
needing to know record count a priori. Better growth calculation for
both NetworkStats and NetworkStatsHistory; 50% each time. Better
estimates of buckets needed in calling services.

Persisting detailed UID stats in separate "netstats_detail.bin" file
to enable different schedules for summary and detail polling. Only
load detailed UID history on demand, since it's not needed during
boot. Add test to verify UID stats are persisted across simulated
reboot.
Move external settings into well-named interface, which is still
backed by Settings.Secure. During periodic poll events, resize any
history to match current bucket duration setting. Test to verify.

Implements read/write of network stats using AtomicFile, along with
magic number and versioning. Stores in "/data/system/netstats.bin"
for now. Tests to verify that stats are persisted across a simulated
reboot, and to verify that TEMPLATE_WIFI is working.
Fixed bug where kernel counters rolling backwards would cause negative
stats to be recorded; now we clamp deltas at 0.

When given a start/end range, interpolate between buckets to return
the total network usage. Used to summarize detailed UID stats. Method
to combine NetworkStatsHistory regardless of bucket size. Used to
combine all histories matching a template.
Added tests for both methods.

Instead of deriving network identity based on raw subsystem broadcasts,
listen for updates from ConnectivityService. Added atomic view of all
active NetworkState, and build map from "iface" to NetworkIdentity set
for stats tracking.
To avoid exposing internal complexity, INetworkStatsService calls use
general templates. Added TelephonyManager mapping to classify network
types using broad labels like "3G" or "4G", used to drive templates.
Cleaned up Objects and Preconditions.
