Move ApfFilter from ConnectivityService to IpManager
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.

Have ConnectivityService install packet filters when possible
Listen for ICMP6 router advertisements on networks that support
packet filters. Construct packet filters and install them to
ignore redundant future ICMP6 router advertisements.

Prompt if a network without an Internet connection is selected
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.

Offer to "merge" subscribers for data usage.
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.)

Add NetworkAgent event for ExplicitlySelected
Lets Wifi tell us when the user selected this AP vs auto-connected.

Implement support for bypassable VPNs.
Bypassable VPNs grab all traffic by default (just like secure VPNs), but:
+ They allow all apps to choose other networks using the multinetwork APIs.
If these other networks are insecure ("untrusted"), they will enforce that the
app holds the necessary permissions, such as CHANGE_NETWORK_STATE.
+ They support consistent routing. If an app has an existing connection over
some other network when the bypassable VPN comes up, it's not interrupted.
