Collect UID-granularity network stats during regular poll event. Add
dumpsys argument to generate fake historical data for debugging, and
move stats parameters to Settings.Secure.

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.

Periodically records delta network traffic into historical buckets to
support other services, such NetworkPolicyManager and Settings UI.
Introduces NetworkStatsHistory structure which contains sparse, uniform
buckets of data usage defined by timestamps. Service periodically
polls NetworkStats and records changes into buckets. It only persists
to disk when substantial changes have occured. Current parameters
create 4 buckets each day, and persist for 90 days, resulting in about
8kB of data per network.
Only records stats for "well known" network interfaces that have been
claimed by Telephony or Wi-Fi subsystems. Historical stats are also
keyed off identity (such as IMSI) to support SIM swapping.

Fixes a race between the onDaemonConnected callback and setting the
mOutputStream in NativeDaemonConnector.
MountService connects to vold using the NativeDaemonConnector.
Throws a “NativeDaemonConnectorException: No output stream!”
when the onDaemonConnected callback in MountService calls the doListCommand.

Adding unsolicited events to response queue
results in doCommand() returning the wrong
result.
Pulling this change from master.

If the sending of the command fails we should note it and not wait forever
for the response.
We should also not say we're ready until we actually are.

The buffer was being compacted in the read loop, but the start offset on
the compacted buffer wasn't being considered after the next read.

In NativeDaemonConnector.doCommand() calls, there was inconsistent error
checking. This change adds error checking for every call and makes it so
that any call to .doCommand() that gets an error code won't cause the
code to hang forever.

If NativeDaemonConnector hits its buffer limit, it would truncate the
data and lose some information. This change compacts the buffer and then
retries to read the rest of the data.
