This is the same notification as the one shown during legacy lockdown
mode, sans the 'reset' button.
The notification is only shown during times when VPN has not yet
established or has failed, for example during boot or after a crash.

Similarly to ApfTest, this patch changes ConnectivityServiceTest to use
a mock object instead of IpConnectivityLog so that running
ConnectivityServiceTest does not generate android.net.metrics events.

This patch creates a new permission used by ConnectivityService to give
access to restricted networks without the NET_CAPABILITY_NOT_RESTRICTED
capability bit on.

This patch adds NetworkInfo BLOCKED/UNBLOCKED status of apps to
ConnectivityService's dump logs.
The BLOCKED or UNBLOCKED status of an app is logged with the app uid
when the app calls getActiveNetworkInfo().
Examples:
mNetworkInfoBlockingLogs (most recent first):
07-11 11:04:43.139 - BLOCKED 10060
07-11 11:04:39.056 - UNBLOCKED 10061
07-11 11:04:38.851 - BLOCKED 10061

The two major changes here are:
- Move lingering out of NetworkMonitor. The fact that lingering
is currently its own state in NetworkMonitor complicates the
logic there: while a network is lingering it cannot be in any
other state, we have to take care not to leave LingeringState
for the wrong reason, etc.
- Instead of keeping a single per-network boolean to indicate
whether a network is lingered or not, keep a linger timer for
every request. This allows us to fix various corner-case bugs
in lingering.
The changes in behaviour compared to the current code can be seen
in the unit test changes. Specifically:
1. Bug fix: when a network is lingered, and a request is added
and removed to it, the existing code tears the network down
immediately. The new code just sends another CALLBACK_LOSING
and resumes lingering with the original timeout.
2. Bug fix: if cell is unvalidated and wifi comes up and
validates before cell does (as might happen on boot), the
existing code immediately tears down cell. The new code
lingers cell, which is correct because unvalidated cell was
the default network, so an app might have been using it.
3. Correctness improvement: always send CALLBACK_AVAILABLE for
the new network before sending CALLBACK_LOSING. This was not
really an issue in practice, because the usual flow is:
- Network A is the default.
- Network B connects, CALLBACK_AVAILABLE.
- Network B validates, CALLBACK_LOSING.

As explained in the TODO, the loop serves no purpose since only
one network can be satisfying a given request at a time.
Instead of looping, look up the nai in the mNetworkForRequestId
array that exists for this purpose.
Keep the loop around with an Slog.wtf statement on it so we can
see if we ever hit it, and add a TODO to delete it if we don't.

http://ag/1194313 broke unregisterNetworkCallback because the
system does not parcel the type of the request back to the app.
So when the app calls unregisterNetworkCallback, the
NetworkRequest that's passed in does not have a type and thus
doesn't match the request in mNetworkRequests.
Fix this by parceling over the type as well.
This was not caught by the unit test because the unit test all
runs in the same process with no parceling.

Ensure every public method is annotated with why it's public.
This can be either an @Override or @VisibleForTesting annotation
or a comment explaining why it's public.

This allows us to keep track of how many live requests a network
is satisfying without having to count them every time.

This will allow us to simplify code that deals with
NetworkRequests outside ConnectivityService.

1. Support multiple callbacks in TestNetworkCallback. This is
necessary to test situations where multiple callbacks are
generated by the same event (e.g., CALLBACK_LOSING on cell
with CALLBACK_AVAILABLE on wifi when wifi connects), which is
necessary to test callback order. So far this has not been
covered because all callback testing was using per-network
callbacks.
2. Add a benchmark test for registering NetworkRequests and for
sending onAvailable and onLosing callbacks.
