Transport may use the redirect to make additional determination about network
state.

Added not_metered capability to a mobile network if none
of its associated APN types are metered. Also used not_metered
capability to determine if a network should be accounted for
data usage or not instead of using network type, which is
always MOBILE after refactoring. Will add VT usage support
in next phase.

Callers with CONNECTIVITY_INTERNAL permission can read off the netId
that an application is assigned to by default.
Necessary for making connections as the default network for a client
app eg. when downloading stuff on its behalf.

Since Lollipop, routes are isolated within Networks. Flushing a
Network's DNS cache whenever that same Network's routes are updated
doesn't provide any benefit. Any system components depending on this
behaviour need to uncovered and fixed.
Additionally, clean up no-longer-used flushNetworkDnsCache(). This
should be replaced, when needed, by a proper binder interface to netd.

There's a few advantages to having ApfFilter in IpManager:
1. If things go wrong, crashing a particular transport is less bad then
crashing ConnectivityService. We also don't want to use
ConnectivityService as a dumping ground for transport-specific logic.
2. This makes implementing WifiManager.MulticastLock a lot simpler and
safer because enabling/disabling it doesn't have to go through the
NetworkAgent, which could risk various races (e.g. installing a filter
into the wrong WiFi network).
3. IpManager is the ultimate source for LinkProperties for a particular
transport and since ApfFilter uses the LinkProperties it's better to
have it closely paired with the IpManager. Likewise, ApfFilter needs
to know the APF capabilities of the transport, so having it in
the transport avoids having to parcel this information through the
NetworkAgent.

Adds initial support for IP connectivity metrics collection (DHCP
client, IP reachability monitor, network monitor, connectivity
service).

The "default network tracking" request is somewhere between a listen
and a request, in previous semantics. It is more like a listen in that
it doesn't cause any network to be brought up, but also like a request
in that will only get callbacks about a single network at a time (not
all networks that might match).
This change minimally splits the NetworkRequest types into 3: LISTEN,
REQUEST, and TRACK_DEFAULT.

Create a common singleton thread to be shared among all
connectivity tasks. Instead of launching separate threads to
handle downstream messages from the various service instances used
in connectivity, these managers can choose to share this instance.

Occasionally, ConnectivityServiceTest fails with "BUG: only one
idle handler allowed". I have not been able to reproduce this
consistently, but code inspection reveals an unsafe access to
mIdleHandler inside queueIdle. Wrap that in a synchronized block.

1. Store additional debug information when RA filtering.
2. Add a toString method for RA packets.
3. Make "adb shell dumpsys connectivity apf" dump APF filter
state.

Sometimes USER_UNLOCKED can be sent before USER_STARTED. This puts
lockdown in a bad state as it needs a fully-functioning user to tie
itself to and listen for connectivity events.

If there are SYSTEM permissions, then the original is SYSTEM permissions,
do not update. If other app of this uid have network permissions, the same
as before do not update, or update permissions. If all app of this uid
do not have any network permission to remove permissions.

1. Override WakeupMessage with an implementation that uses
sendEmptyMessageDelayed. This allows us to replace a
6-second sleep with a 150ms wait.
2. Change waitFor()'s polling interval from 100ms to 50ms.
With these changes ConnectivityServiceTest goes from ~9s to ~3s.

Apps making calls into the system server may end up persisting
internal state or making security decisions based on the perceived
success or failure of a call, or the default values returned.
The reality is that if the system process just died, init will be
along shortly to kill all running apps, so we should have no problem
rethrowing the RemoteException as a RuntimeException.

NetworkStatsService will register data usage requests
and keep data usage stats scoped to the request.
There are different types of data usage requests
- scoped to a set of NetworkTemplate; these are restrictred to
device owners and carrier apps and allow the caller to monitor
all activity on the specified interfaces.
- scoped to all uids visible to the user, if the user has
android.Manifest.permission#PACKAGE_USAGE_STATS permission.
The set of uids may change over time, so we keep track of that.
- scoped to a set of uids given by the caller, granted that
the caller has access to those uids.
- scoped to the caller's own data usage. This doesn't require
PACKAGE_USAGE_STATS.

With this it's possible for callers to:
Network network = ...
LinkProperties lp = ...
NetworkDiagnostics netdiag = new NetworkDiagnostics(network, lp, 5000);
netdiag.startMeasurements();
netdiag.waitForMeasurements();
boolean result = true;
for (Measurement m : netdiag.getMeasurements()) {
if (!m.checkSucceeded()) {
result = false;
// Additional error handling here.
}
