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

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.

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.

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.
}

When the roaming status of the cell network changes, it is handled as
follows:
-DcActiveState gets an event (either EVENT_DATA_CONNECTION_ROAM_ON or
EVENT_DATA_CONNECTION_ROAM_OFF) and calls
NetworkAgent#sendNetworkInfo with updated NetworkInfo.
-ConnectivityService then gets an EVENT_NETWORK_INFO_CHANGED and calls
updateNetworkInfo with the new info.
With the previous code, the NetworkAgent's NetworkInfo object would be
updated internally, but because the state of the connection had not
changed from CONNECTED, the change would be considered a duplicate and
otherwise ignored.
With the new code, we call notifyIfacesChanged() when the state is the
same but the roaming status has changed. That should be all that is
necessary, as roaming is not exposed as a link property or network
capability today.

This intent will be broadcasted when:
- Global restrict background setting is changed (sent to all packages)
- An individual uid is added to or removed from the whitelist (sent just
to the packages belonging to that uid).
This intent is only sent to registered receivers.

This will make it possible to find nethandles via, e.g.
"dumpsys connectivity --short".
Without this, native multinetwork API debugging requires running
"dumpsys connectivity --diag" in order to see the nethandle values.
