We often get told a network has gone away after the interface is downed
and the routes are auto-removed. Change the log to VDBUG so standard
builds don't have the noise.

Also allow isActiveNetworkMetered() to inspect networks without
requiring ACCESS_WIFI_STATE.

Report to developers if active network is "metered" and define it
as the user being sensitive to heavy data usage.

Users outside system_server now explicitly communicate their
lifecycle, which keeps a strong-reference chain to any fully loaded
NetworkStatsCollection histories.

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.

writePidDns() does not increase the index in case first given dns
already exist in the property.

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.

Backported from master, including a bug fix and a cdma enhancement.
Even if other people are sharing the connection (ie, carrier wants
default and tethered traffic on the same APN) stop using a carrier-
described APN when the tethering stops.

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

special network is not available output some additional information.
