When WiFi disconnects, the VPN disconnects immediately. The
broadcast can therefore be sent before the broadcast receiver is
registered, which causes the receiver to not see the broadcast.
The puzzling part is that CONNECTIVITY_ACTION is a sticky
broadcast, so one would expect the broadcast to still be
received, even if the registration is done after the broadcast
is sent. The reason this doesn't happen is that the context used
by the test is a BroadcastInterceptingContext, which does not
treat sticky broadcasts as sticky.

It isn't used by ConnectivityService any more and even if
it needs such utility method in the future, we could create
one which is part of connectivity module and doesn't need
to be exposed as part of NetworkPolicyManager API surface.

Currently, queryUserAccess talks to netd via FwmarkServer.
Doing this from the module would require exposing queryUserAccess
as an NDK API or reimplementing FwmarkClient.
Because queryUserAccess really only uses information that comes
from ConnectivityService/PermissionMonitor anyway, just use that
information without calling to net.

- This will be visible only to apps with the NETWORK_SETTINGS
permissions (signature), and will be redacted for all other callers.
- This string is expected to be the same as set by
VpnService#setSession, and in general, VpnConfig.session. But it
will be a general API that Vpn.java can call when setting the
VpnTransportInfo.
- This string cannot be updated once the VPN NetworkAgent is connected.

This is similar to onBlockedStatusChanged(Network, boolean) but
it allows the callback holder to know the exact reason why
networking was blocked. It is useful to privileged system
components such as JobScheduler that are able to ignore some
blocked reasons but not others.
Also add a new BLOCKED_REASON_LOCKDOWN_VPN that is used when
networking is blocked because an always-on VPN is in
lockdown mode.
Also move BLOCKED_METERED_REASON_MASK to ConnectivityManager.
This is necessary because ConnectivityService must ensure that
the blocked status callbacks are correctly sent when meteredness
changes (e.g., a UID that is blocked on metered networks will
become unblocked on a network that becomes unmetered). In order
to do this it needs to know which reasons apply only on metered
networks.

This exposes a mechanism for network providers to tell
the network stack that a given network must be kept up
for some specific reason. This is meant to be easier
for them than to have to file a request, in particular
because there is no guaranteed way to make sure the
request will be best matched by any given network.

The design is very simply expressed :
An offer is needed for a request if and only if that offer
might beat the satisfier for that request.
The implementation of "might beat" is NetworkRanker#mightBeat.
