New broadcast that is dispatched immediately after connectivity
changes have been handled by ConnectivityService, bypassing any
applicable CONNECTIVITY_CHANGE_DELAY.
Also protect CONNECTIVITY_CHANGE broadcasts, since they should only
be sent by system.

When recording data usage, measure the actual active time, since
buckets can be quite long. Offer incrementOperationCount() version
that reads thread stats tag for caller. Rethrow any NPE as ISE
during stats parsing, which callers already handle.

Instead of polling every 15 minutes, register for alerts that trigger
when system-wide traffic passes a threshold. Still mixed with polling
to persist UID stats, but relaxed to 30 minutes. Currently watches
for every 512kB.
Make persistence decision separately for network versus UID, and use
total delta bytes when making decision. Use light bootstrap during
systemReady() instead of heavy poll, which had been force-loading all
UID data unnecessarily.

Add policy controls to NetworkStateTracker which are combined with
other user preference and internal flags to decide if data connection
should be established. Better locking around enabled flags.
When data network would be over limit, proactively disable data on
that network. Enable when policy is snoozed or when cycle resets.
Track and dismiss notifications from now-stale policies.

When restricting background data, show ongoing notification to give
easy access to re-enable. Deprecate getBackgroundDataSetting() API
to always return true, since NetworkInfo.isConnected() is new source
of truth. Handle upgrade path by reading from existing secure value,
and kick one last broadcast when changing value. Remove background
data code from ConnectivityService.
Remove warning alerts, since they push ifaces into restricted list;
should only happen when iface has limit.

Teach NetworkStats about "counter sets" coming from kernel, and use
them to track usage in foreground/background. Add AID_NET_BW_ACCT to
system_server so it can control counter sets.
Move to composite key of NetworkIdentitySet, UID, set, and tag when
recording historical usage. Persisting still clusters by identity,
since that is heaviest object.
Request async stats poll during systemReady() to bootstrap later
delta calculations. Reset kernel counters when UID removed. Update
various tests.

Persist NetworkStatsHistory using variable-length encoding; since
most buckets have small numbers, we can encode them tighter. Initial
test showed 44% space savings. Also persist packet and operation
counters.
Let NetworkStatsHistory consumers request which fields they actually
need to reduce parcel overhead.
Tests for verify varint and history field requests, also verify end-
to-end by persisting history into byte[] and restoring. Expose
bandwidth control enabled state. Extend random generation to create
packet and operation counts. Moved operation counts to long.
Fix bug that miscalculated bytes since last persist, which would
cause partial stats loss when battery pulled.

Create API to expose quota status derived from underlying network
policy. This is designed to support applications making informed

Fix bug with random stats generation, and write policy when changing

Provide API to increment "operation counts" for a UID and tag, used
to eventually derive bytes/operation stats. Internally is stored at
network layer, but should belong at data layer. Switch profiling
to use data layer stats, which are emulated by summarizing network
layer details.
Read packet counts from new /proc/ columns and collect them into
NetworkStatsHistory. Prevent double-counting by ignoring values from
first snapshot. Watch for duplicate /proc/ entries. Update tests
to verify packet and operation counters.

The previous approach no longer works with the new USB drivers, since the usb0
interface is no longer enabled by default.
This introduced a chicken & egg problem - usb0 will not be enabled until the
user tries to start tethering, but Settings will not enable the checkbox unless
usb0 is enabled.
To fix this we add an explicit call to start USB tethering in the connectivity manager.
This will enable RNDIS if necessary and then bring up tethering once usb0 is enabled.

We'd been doing no-gateway hostroutes for dns servers on secondary nets, but on
some devices (multi-homed stingray) this is a problem. Add gateway-ed hostroutes
instead so the BP can do it's nonstandard "magical" demultiplexing.

If an address is removed we must reset the connection but

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.
