Properly account for VPN apps that make heavy use of the tun
interface. Prior to this change a VPN app could be incorrectly charged
for more data than it actually used if it sent more traffic through
the tun interface than the underlying interface.
This change excludes VPN app traffic on the tun interface from the
adjustment pool and doesn't redistribute traffic to the VPN app.
Instead all of the redistributed traffic is deducted from the VPN app
which effectively represents any overhead incurred by the VPN app.

When fetching system services early during boot, if the underlying
binder interface hasn't been published yet, we end up caching a
manager class that is broken for the remainder of the process
lifetime, and innocent downstream callers end up using the broken
cached manager.
Fix this by using an explicit exception to quickly abort manager
creation when the underlying binder is missing. The exception is
only used to skip the remainder of the manager creation, and it
doesn't actually crash the process.

The IpConnectivityLog class looks up MetricsLoggerService once only
at creation. If a IpConnectivityLog user instantiates this class too
early during the boot process, the MetricsLoggerService is not found
and no event can be recorded.
This patch makes IpConnectivityLog attempt to look up
MetricsLoggerService as long as it hasn't found it yet.
This allows IpManager and ConnectivityService to upload
android.net.metrics events.

Add an IPv6TetheringCoordinator to TetheringMaster StateMachine, which
receives and processes NetworkState updates and passes the necessary IPv6
information to the revelant TetherInterfaceStateMachine.
Add an IPv6TetheringInterfaceServices to TetherInterfaceStateMachine, which
is responsible for adding local network routes and managing an IPv6

This patch adds in IpReachabilityMonitor a timestamp variable set
everytime that probeAll() send NUD probe requests to RTNETLINK.
This allows to distinguish between:
1) NUD_FAILED events resulting from such a forced NUD probe
2) "organic" NUD_FAILED notifications from the kernel
This distinction is added to IpReachabilityEvent as a one-bit flag.
This patch also changes the formatting of ApfProgramEvent flags to use
'|' as a joining character, similarly to other flags formatting.

This patch partially undoes ag/869831 (Change-Id:
Ia42ed7aefaebd8caf3eada8e42b6cb7a940d7647) so that ConnectivityManager
does not remove callbacks from its internal request-to-callback map at
unregistration, but instead let the singleton CallbackHandler do it when
receiving a CALLBACK_RELEASED from ConnectivityService.
ag/869831 was thought to fix b/26749700 that reported a callback leak
from sNetworkCallback, but a finer analysis of the code shows that
callbacks were correctly removed by the CallbackHandler before
ag/869831. There was therefore no callback leak.

The older Time class is deprecated and doesn't handle edge cases
very well. So migrate the cycle calculation logic to use the
long-standing and well-supported Calendar API.
