This change adds a comment to CS#simulateDataStall to explain why the
Data Stall is wrapped in a DataStallReportParcelable before being passed
to the ConnectivityDiagnostics handler. This approach is taken to ensure
that simulated data stalls are handled the exact same as Data Stalls
received directly from NetworkMonitor (including Data Stalls detected by
methods that the platform does not understand).

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 saves dozens of warnings every time FrameworkNetTests is

LegacyTypeTracker's reason for existence is to power deprecated

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).

(partial cherry-pick of internal change:

With b/150232615, we will need an explicit value set for the exported
flag when intent filters are present, as the default behavior is
changing for S+. This change adds the value reflecting the previous
default to the manifest.
These changes were made using an automated tool, the xml file may be
reformatted slightly creating a larger diff. The only "real" change is
the addition of "android:exported" to activities, services, and
receivers that have one or more intent-filters.

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
place.

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.
