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.

Added a new network capability TEMOPORARILY_NOT_METERED to support
the case that a network can temporarily become unmetered. This
allows carriers to deploy unmetered 5G network. When devices
camp on 5G network, this capability will be dynamically added
to the network and will be removed once leaving 5G coverage.

MatchAllNetworkSpecifier is a subclass of NetworkSpecifer. The method
satisfiedBy should be renamed to canBeSatisfiedBy together with other
subclass of NetworkSpecifer in b/152238712.
Add annotation @Overide for the method to make sure it will not get
ignored when refactor in the future.

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
entries left and cause exception.

This change adds a TestApi for simulating a Data Stall to
ConnectivityService. This allows for Data Stalls to be triggered without
having to manipulate the signals used by NetworkMonitor . This also
allows NetworkMonitor to update the ways it detects Data Stalls without
affecting CTS tests for ConnectivityDiagnosticsManager.

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.

464xlat will never be started on a network that is not connected,
or on a network that has no IPv6 address.
This is a no-op test-only change but it is necessary for an

currently made by this test and causes it to fail.

The NAT64 prefix from the RA always takes precedence over the
NAT64 prefix from DNS discovery, because it is detected faster,
