Introduce a SharedLog that can be shared among all Tethering
components. All log entries go to the same log, and each includes
its subsystem name. Additionally, all entries emitted to the
system log shared the same tag, so can easily be watched.
More subsystems can inherit a SharedLog, but to minimize cherry-pick
conflicts we limit ourselves to these changes only.

- built

This path changes a dangerous lock path in reportNetworkConnectivity().
This methods is called outside of the main ConnectivityService handler
and takes a lock on a specific NetworkAgentInfo whose connectivity
status is being reported.
While this lock is held, reportNetworkConnectivity() goes on and query
the network policy state for that network, which may ends into
NetworkPolicyManagerService.
Instead, the lock on NetworkAgentInfo is only held long enough to make a
copy of LinkProperties, which is then passed to
NetworkPolicyManagerService without that lock.

Test: could not repro b/36902662, reportNetworkConnectivity() works.

This change introduces new methods on DumpUtils that can check if the
caller has DUMP and/or PACKAGE_USAGE_STATS access. It then moves all
existing dump() methods to use these checks so that we emit
consistent error messages.

This patch removes from ConnectivityService the logic involved in
deciding if a uid has access to networking based on networking policies.
This logic is moved into NetworkPolicyManagerService which is the source
of truth with regards to the state of networking policie, both for
existing networks and uids.
Instead ConnectivityService directly queries NetworkPolicyManagerService
in a synchronous fashion for a specific uid or a (uid, network) pair.
This eliminates the need to keep a copy of the uid policy rules inside
ConnectivityService and ensures that ConnectivityService takes
networking decisions based on the correct state of networking policies,
and therefore eliminates certain data races in ConnectivityManager API
that applications are exposed to.

The request network with timeout was originally created with a
check of max timeout against a constant of 100 minutes. However,
the API was not public and did not implement a timeout. Any users
were internal and never got any onUnavailable() callback (since
timeout never triggered).
There is no reason to have a max timeout so the constant is
remove.

doing so is desired.

Lockdown VPN still needs this to start properly on devices without FBE,
such as phones upgraded from M. Without listening to USER_PRESENT the
first unlock of keystore may get missed, since USER_UNLOCKED is sent too

This patch improves system logging around captive portal detection to
make inspection of bug reports sligthly easier:
- NetworkMonitor now logs by default CMD_CAPTIVE_PORTAL_RECHECK and
CMD_CAPTIVE_PORTAL_APP_FINISHED. Other system logs are kept off with
a new VDBG boolean contant,
- NetworkNotificationManager now prints the notification id at
notification time. This allows to easily correlate show and clear.
- errors in NetworkNotificationManager are logged as Throwable instead
of through their implicit toString() method.
