When a network is explicitlySelected, keep it connected but do
not automatically switch to it. Instead, attempt to validate it,
and if 8 seconds have passed and the network is not yet
validated, prompt the user asking whether to switch to it anyway.

1. If reportInetCondition says the network is not working, and
the network is already marked not validated, don't revalidate
it. This was superfluous and should save battery.
2. If reportInetCondition says the network is working, and the
network is not marked as validated, revalidated. This will
allow us to get out of a validated state quickly based on app
input (e.g., allowing GCM's exponential backoff timer to drive
revalidation instead of our 10-minute timer).

If a user is subject to a VPN, getActiveNetworkInfo() will return
the VPN's underlying network (e.g., TYPE_WIFI), so that apps that
call getActiveNetworkInfo to answer questions like "is the device
connected to wifi?" will continue to work. Make getNetworkInfo
do this as well: if the query is for a network type that is
underlying the current user's VPN, then return that network.

A legacy network type request would generate a bcast before the network
notification was sent - the legacy startUsingNetworkFeature API requires
the notification so it can bind your dns queries to the new network.
Fast-moving clients could try to use the network before it was ready.

When we switched the way the status bar determines if a
connection is validated from using INET_CONDITION_ACTION
broadcasts to calling getDefaultNetworkCapabilitiesForUser(),
the statusbar stopped displaying ! when a network stopped having
working Internet connectivity. This is because the validated bit
is never set to false once a network is validated.
Fix this, hopefully temporarily, by introducing a new validated
bit that does go back to being false when a network no longer
has working connectivity, and use that bit in
getDefaultNetworkCapabilitiesForUser().

Now that the delay between connectivity changes and CONNECTIVITY_ACTION
has been removed (ag/599650) races between CONNECTIVITY_ACTION and
the setting of the default network become more evident.
In http://crbug.com/441818 Chrome is calling getaddrinfo()
immediately after a device goes from no connectivity to cellular
connectivity, and Chrome is erroneously getting back EAI_NODATA
because netd hasn't yet set the default network for DNS resolutions.

1. Send PROXY_CHANGE_ACTION broadcast when any network's proxy changes,
not just the default network.
2. When a process is bound to a particular Network, update the proxy
system properties to those for the bound Network, and keep them
updated when PROXY_CHANGE_ACTION broadcasts are received.
3. Make Network.openConnection() use the proxy for the Network.

Connectivity broadcasts recently changed and are no longer sent for
certain types of network changes. For example, when stacked network
interfaces change for a mobile network. To ensure that we pick up
all these details, directly wire the two services together.

There are some cases where multiple subscriber identities (IMSI)
should be treated as "merged together" from a data usage
perspective. This is done by extending the template used for
matching purposes to support multiple subscribers.
Then, when we query historical usage or set network policies, we
normalize the matching template to merge to any other identities
that should be included. When normalizing, the "lowest" identity
is always used for equality and storage purposes, which allows
identities to come and go over time.
This change also fixes data usage recording for multi-SIM devices
by passing along the concrete subscriber identity for each network
interface. Also correctly create default policies for multi-SIM
devices. This change also drops setPolicyDataEnable() until it can
be wired up to the right underlying NetworkAgent. (This means we
still bring up the network, and then rely on iptables rules to block
traffic when over the limit, instead of proactively disabling the
connection.)

These networks are unneeded and waste battery. We won't bring up these
networks in the first place if they have no chance of becoming highest scoring.
This change handles the case where these networks are already up and
transition to a state where they have no chance of becoming highest scoring.
This happens when another network validates with a score higher than this
network can ever hope to attain.

The basic principle is: if an app's traffic could possibly go
over a network without the app using the multinetwork APIs (hence
"by default"), then the status bar should show that network's
connectivity.
In the normal case, app traffic only goes over the system's default
network connection, so that's the only network returned.
With a VPN in force, some app traffic may go into the VPN, and thus over
whatever underlying networks the VPN specifies, while other app traffic
may go over the system default network (e.g.: a split-tunnel VPN, or an
app disallowed by the VPN), so the set of networks returned includes the
VPN's underlying networks and the system default.
Specifically:
1. Add a NETWORK_CAPABILITY_VALIDATED bit to NetworkCapabilities.
2. Add a hidden API to retrieve the NetworkCapabilities of
all default networks for a given macro-user.
3. Modify the status bar code that used getActiveNetworkInfo to
determine which network was active, and make it consider all
validated networks instead.
4. Because the set of active networks depends on which VPN app
the user is running, make the status bar re-evaluate the
networking situation when the active user changes.

Currently, if a network does not specify DNS servers, we default
it to using 8.8.8.8. This was done because the emulator did not
specify DNS servers. However, it causes queries to fail slowly,
instead of failing fast, on networks that do not have
connectivity to 8.8.8.8.

GCM can call reportInetCondition() at any time which can cause
the NetworkMonitor to transition states to reevaluate at any time.
Previously we were only listening for users clicking the sign-in
notificaiton or completing sign-in when in the appropriate state.
With this change NetworkMonitor's state does not stop us from
listening for the user's actions.

If a VPN app requests to be prepared and has already obtained user
consent, there is no need to additionally enforce the control
permission. We only need to enforce the control permission when a VPN
is first being prepared, where such a preparation would bypass user
consent.
Also ensure that in this case, the VPN being prepared matches the
calling app. Otherwise an app could prepare another pre-consented VPN,
which is not particularly dangerous but is likely unexpected.
Finally, remove misleading comment in ConnectivityService#prepareVpn.
This method IS called from VpnService.prepare(), not only from
system-privileged apps.
