This is only necessary when learning the NAT64 prefix from the
RA, because if the NAT64 prefix is learned from DNS, the DNS
resolver already knows the prefix and automatically enables
DNS64 synthesis.
The DNS resolver needs to be informed of the prefix any time
clat is running on a prefix learned from an RA. This is simple to
implement: just set the prefix when starting clat if prefix
discovery is not running, and clear the prefix when stopping clat
if prefix discovery was not running. This ensures that the prefix
is cleared iff it was set.

This is not particularly likely to happen unless the pref64 RA is
sent by a different router than the main RA. But more tests are
always good, and this additional coverage will be more useful
in an upcoming change.

As NetworkAgent is in a transition where all agents need
to include the NOT_SUSPENDED capability as part of their
migration to the system API, ConnectivityService adds it
forcefully to all agents that don't have the CELLULAR
transport. This doesn't include VPNs when VPNs have some
cellular network as their underlying network.
The best way to solve this is to make sure the VPN
capabilities reflect those of the underlying networks as
far as the NOT_SUSPENDED capability is concerned. This
is how they work for other similar capabilities.
This also happens to contain a drive-by fix for an issue
with a spurious capabilities callback is triggered when
a VPN connects and it has any underlying network (which
means almost always, because it will take the default
network if it doesn't declare any). Fixing this was
necessary to have a cogent test of this issue, but it
could be moved to another patch or it could stay unfixed
with some minor ajustment to the tests if judged too
dangerous to include in R at this point.
Test: New tests in this patch. Also manually tested with
tcpdump as described in b/150570873.

When a VPN connects and it has any underlying network (which
means almost always, because it will take the default network
if it doesn't declare any), it has default capabilities and
will only take the capabilities of its underlying network
as part of an update happening after making the network
available but before the rematch can take place. This in turn
causes the capabilities callback sent as part of the rematch
to be spuriously sent.
Test: FrameworksNetTests. Also tested together with a
followup that adds tests with drive-by coverage for this.

NetworkStats calculation needs to filter out debug entries to
prevent over counting. While NetworkStatsFactory migrates data
usage over a VPN to the TUN network, NetworkStatsFactory does
not filter out debug entries per vpn which will cause debug

Currently, if a prefix is learned from an RA while prefix
discovery is running, clatd will be correctly started, but
prefix discovery will be stopped.
In order to fix this, make it possible to call
stopPrefixDiscovery without transitioning to IDLE state (which
is obviously necessary in this case), by moving the assignment of
the next state from that method to its callers. For consistency,
do the same for startPrefixDiscovery.

This commit adds support for validating and filtering IPsec algorithms.
Without a public API exposing IKEv2 algorithms (and their respective
public APIs), the allowedAlgorithms can only filter the proposals for
IPsec (Child) SA algorithms.
Additionally, this removes the HMAC_SHA1 from the IKE SA's integrity
algorithm proposals due to insecurity

For a given network, resolver doesn't know what transport types are.
Therefore, when a new network is created or transport types are changed
in a give network, transport types will be updated and sent by calling
setResolverConfiguration(). In the same time, if link properties or
transport types are null, setResolverConfiguration() won't be called.
The original behaviors of setResolverConfiguration() aren't changed.
Only increasing one new behavior that when a given network has transport
type change, calling setResolverConfiguration() directly and resolver
updates the transport types for that given network.
