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.

This CL forwards suspected Data Stall events detected with unknown
detection methods to ConnectivityDiagnostics.
Currently, ConnectivityService drops any data stall events with unknown
detection methods, which leads to false negatives for Connectivity
Diagnostics registrants. This change ensures that registrants will still
be notified as NetworkStack is updated to use new detection methods.
The documentation for ConnectivityDiagnosticsManager#DataStallReport is
also updated to reflect that the detection methods included in the
report are a bit mask of detection methods used. Implicitly, this means
that data stalls detected via unknown methods will have an empty bit
mask (0x00).

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.

This change moves the logic for handling Data Stall notifications from
NetworkMonitorCallbacks to ConnectivityService. This avoids duplicate
logic for managing data stall simulation requests from
ConnectivityManager. This also puts all of the logic for proxying Data
Stall notifications to the ConnectivityDiagnosticsHandler into one

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

This change adds tests to validate that both transport and tunnel mode
transforms continue to work even after the SPI resource has been
released. Specifically, since SPI resources are effectively subsumed by
the creation of a Transform, the SPI resource is still "alive", but
removed from the user-tracking sparse arrays.

(cherry picked from commit d06d390b20)
IpSecService.applyTunnelModeTransform() currently does not take an
SpiRecord instance, yet implicitly requires that the SpiRecord instance
is still alive based on the stored SpiRecord resourceId in
the TransformRecord's IpSecConfig.
This check is unnecessary, as the SpiRecord has been subsumed into the
TransformRecord, and the kernel resources are kept alive whether or
not the SpiRecord is still held by the user.
This allows users of the IpSecManager API to allocate short-lived SPIs
during the creation of an IpSecTransform, without having to keep track
of both of them (even though the SPI is no longer usable).
The TransformRecord.getSpiRecord() call is already used in
multiple other places in the same method.
