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.

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.

Teach NetworkPolicy limits to "snooze" when requested by user, and
notify with both dialog and notification. Register for network alerts
through NMS to trigger updates immediately instead of waiting for
next stats update.
Enforce that all NetworkPolicy are unique on a template basis, and
move SCREEN_ON/OFF broadcasts to background thread. Launch SystemUI
and Settings directly instead of using actions, and include full
NetworkTemplate in extras.
Tests to verify notification and snooze behavior.

This is a 1st pass at receiving events that indicate
some quota has been reached e.g. warning quota, data collection quota,
cutoff quota,...
It needs:
- new kernel with quota2 logging support
- new net:bandwidthcontroller that supports
. quota2,
. setting alerts.
- new NetlinkEvent/NetlinkManager/NetlinkHandler to process
NETLINK NFLOG messages.

When NetworkManagementService starts, it determines if qtaguid

property to control socket tagging.

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.

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.

After unreverting the linkstate change patch, hook up notification handlers
that didn't exist when the first patch was created, like
EthernetDataTracker.java and Vpn.java.
For the observers that handle interfaceStatusChanged(), I made
interfaceLinkStatusChanged() call it so they both do the same thing.

This reverts commit 1a7e671902.
Bring back the changes from Stan Chesnutt regarding link-status-change
notifications. The comment from the original patch was:
Propagate new link-status-change message to any NetworkManagementService
observers. Also fix the syntax of the "interface-status-change" message. Add
a null handler in the ThrottleService and Tethering classes (plus fix names).

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.

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.

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.

Added startDataProfiling() and stopDataProfiling() to TrafficStats,
which can be used by apps to measure network usage delta between two
points in time. Currently takes two NetworkStats snapshots and returns
delta, which will eventually include tag-level granularity. Added
tests for NetworkStats delta subtraction.
Added NMS.getNetworkStatsUidDetail() that returns stats for specific
UID. Always gives stats access for the calling UID, otherwise enforces
that caller has permission. Fix readSingleLongFromFile(), since
/proc/ files don't have well-defined lengths.

Introduce NetworkStats which is a collection of network statistics,
which should match the structure communicated by kernel module through
netd. Will introduce tags and fg/bg stats later. Kept entirely in a
flat data structure to optimize parcel speed.

both summary and details. Will eventually pull data from kernel module
over netd connection.
