Add logic to obtain the mtu from the network PCO parameter and set it to kernel
when the mobile data connection is established. When there is no PCO mtu configured
from the network, the mtu size defined in the corresponding APN will be used. In case
no mtu size is defined for an APN used for data connection, the MCC/MNC based MTU
defined in the framework overaly will be applied.

Some devices use clatd for catching raw IPv4 traffic when running on
a pure-IPv6 carrier network. In those situations, the per-UID
stats are accounted against the clat iface, so framework users need
to combine both the "base" and "stacked" iface usage together.
This also means that policy rules (like restricting background data
or battery saver) need to apply to the stacked ifaces.
Finally, we need to massage stats data slightly:
-- Currently xt_qtaguid double-counts the clatd traffic *leaving*
the device; both against the original UID on the clat iface, and
against UID 0 on the final egress interface.
-- All clatd traffic *arriving* at the device is missing the extra
IPv6 packet header overhead when accounted against the final UID.

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.

This eliminates the need for the ConnectivityService.VpnCallback class.
This requires shifting VPNs to the new "network" netd API.
VpnService.protect() is modified to no longer go through ConnectivityService.
NetworkCapabilities is extended to add a transport type for VPNs and a
capability requiring a non-VPN (so the default NetworkRequest isn't satisfied
by a VPN).

1. Make addDnsServer not add duplicate servers and return a
boolean value incating whether it changed anything. This is
consistent with what we do for LinkAddresses and routes.
2. Add a setDnsServers method that sets all the DNS servers to
the specified collection. This is consistent with what we do
for LinkAddress.

In IPv4, a link is provisioned when DHCP succeeds. In IPv6, a
there is no such signal, because addresses and DNS servers can
be notified by the kernel at different times.
Add an isProvisioned method that returns true if we believe that
enough information has configured to use a network. For IPv6,
this requires an IP address, default route, and DNS server. For
IPv4, this requires only an IPv4 address, because we support
static configuration that doesn't have a default route or DNS
server.
To do this we use the existing hasIPv4Address method, rename the
all-but unused hasIPv6Address method to hasGlobalIPv6Address
(which is what we want anyway) and add new hasIPv[46]DefaultRoute
and hasIPv[46]DnsServer methods.

This will allow us to dynamically track routes being added and
removed, similar to what we do for IP addresses.
1. Support removing routes. Since this is a new function, we
don't need to jump through hoops to support callers passing
in routes that have no interface, we just fail to match them.
2. Make the addRoute method return a boolean value indicating
whether anything changed. This is consistent with what we do
for addresses and is used to decide whether to update the
rest of the system when an update comes in.

http://ag/480881 changed RouteInfo.getDestination() to return an IpPrefix
instead of a LinkAddress. This makes the equals() comparison always fail.
So, when ConnectivityService.updateRoutes() is given identical routes, instead
of realizing that there's no diff, it would consider them different, and thus
add and remove the same route. The add would fail, since the route already
existed in netd, but the remove would succeed, leaving the system with no routes
and thus no connectivity.
