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 reading network counters, always splice in xt_qtaguid values
to avoid counting backwards. Test to verify.
Remove verbose logging around global alerts, and add dumpsys debug
info for NMS and MDST. Also fix subtle bug around stats persisting
and dumping.

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.

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.

Now callbacks can communicate to the same daemon without causing a
deadlock. This also improves the latency of calls because they no
longer need to wait for the callbacks for the pending events.

Create API to expose quota status derived from underlying network
policy. This is designed to support applications making informed
decisions when performing network requests.
Fix bug with random stats generation, and write policy when changing
restrict background data flag. Deprecate EXTRA_NETWORK_INFO, since
it varies based on UID.

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.

Only show warning/limit notifications for active networks, since they

When requesting historical values with time ranges, always include
full values for buckets that span current time. (It doesn't make

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

This patch fixes a really annoying bug that prevented the emulator
from properly mounting the SD Card.
The issue was that mOutputStream was not initialized when the onDaemonConnected
callbacks are called, just after the daemon's socket connection is established.
In one specific case (MountService a.k.a. VoldConnector), the corresponding
callback function immediately tried to perform a doCommandList() call on the
connector object. The request failed because mOutputStream was still defined
as null when it happened.
By moving the initialization of the variable just before the callback is
invoked, we ensure that things work properly.
