Add networkId field to NetworkIdentity to identify Wi-Fi networks by
SSID. Add support for policies without usage cycles.
Only apply mobile policies when SIM state is ready, which is cleaner
than just checking for airplane mode. Also avoids creating no-op
default policies when subscriberId is null.

To support multi-user, store network policy per-appId and expand to

Subtype controls (3G-vs-4G) aren't exposed in the UI, so tracking
data with that granularity creates unnecessary overhead. For example,
some GSM networks can regularly flap between two subtypes.

Instead of cycle reset at midnight UTC, use midnight of timezone
active when user last set cycle reset date. Tests to verify, and
also to test leap year behavior.

When Wi-fi connects at L2 layer, the beacons reach and the device
can maintain a connection to the access point, but the application
connectivity can be flaky (due to bigger packet size exchange).
We now use Watchdog to monitor the quality of the last hop on
Wi-Fi using signal strength and ARP connectivity as indicators
to decide if the link is good enough to switch to Wi-Fi as the uplink.
ARP pings are useful for link validation but can still get through
when the application traffic fails to go through and thus not best indicator
real packet loss since they are tiny packets (28 bytes) and have
much low chance of packet corruption than the regular data
packets.
Signal strength and ARP used together ends up working well in tests.
The goal is to switch to Wi-Fi after validating ARP transfer
and RSSI and then switching out of Wi-Fi when we hit a low
signal strength threshold and waiting until the signal strength
improves and validating ARP transfer.

Previously we were starting DHCP as soon as the interface was added,
which is at boot on devices with builtin ethernet.

When a cable was unplugged, we were telling the driver to release the
ip address so if a cable on a different network was plugged in, it would
still try to use it's old ip address on the new network, which probably
didn't work.
Also, we didn't notify ConnectivityService about the state change in
the unplug case. Some of this was done in the interface removed case,
but we never remove the interface in Tungsten, just unplug. So refactor
the common disconnect code into a disconnect() function that's called
by both the link status change (unplug) and interface removal (only applies
to things like USB ethernet dongles) cases.

When changing global restrict background status, send connectivity
change broadcast, since it radically changes DISCONNECTED/BLOCKED
status system-wide.
Also reduce verbose stats logging.

Introduce second snooze timestamp to support dismissal of data usage
warning notification. Also explicitly set notification "when" to
avoid fighting with other notifications, such as ongoing downloads.

Helps developers create well-behaved intents:
- lower case MIME data type
- strip parameters from MIME content types
- lowercase URI scheme
The new API's are
normalizeAndSetType()
normalizeAndSetData()
normalizeAndSetDataAndType()
Uri.normalize()
normalizeMimeType()

Split existing network stats into two separate classes: a recorder
which generates historical data based on periodic counter snapshots,
and a collection of historical data with persistance logic.
Recorder keeps a pending history in memory until outstanding data
crosses a specific threshold. Persisting is handled through a given
FileRotator. This pattern significantly reduces disk churn and
memory overhead. Separate UID data from UID tag data, enabling a
shorter rotation cycle. Migrate existing stats into new structure.
Remove "xt" stats until iptables hooks are ready. Avoid consuming
Entry values when recording into NetworkStatsHistory. Assign
operation counts to default route interface.
Introduce "Rewriter" interface in FileRotator with methods to enable
rewriteAll(). Introduce IndentingPrintWriter to handle indenting in
dump() methods.

This separates the definition of "metered network" and "network with
