Registering for carrier config changes can deliver a sticky broadcast
and can cause Tethering to think something has changed and reevaluate
provisioning status, even though this has been checked before it
entered tethering mode alive state.
Additionally, move the provisioning_app{,no_ui} resources into the
TetheringConfiguration, if for no other reason than now we can log
it in .toString().

Tethering currently wants access to complex isTetheringSupported
logic that is only available in ConnectivityService. Instead of
trying to access that via ConnectivityManager, pass this capability
in to Tethering directly, in the TetheringDependencies object.
Also:
- ConnectivityManager is only a source of static constants now,
so "import static" all the constants that are actually used.

In evaluating whether "most" of the addressing space is
covered, the list of routes are obtained from a third-party
app, so it's possbile the system service stalls unless
some limit is enforced on how much work it has to do.
This change limits the number of routes to 400, as determined
by time measurement on various devices.

When switching from a validated default network to a new validated
default network (typically because of a better score),
DefaultNetworkMetrics would not reset the last validation timestamp.
This would cause the new default network to have a total recorded
validation time overcounted by the validation time of the previous
default network.
The following fix should be applied downstream for consumers of
previously recorded data:
validation_time = min validation_time, duration_time);

Change-Id: I2c36860f976898883714f72f4d18e06da250c6a6
This patch changes instrumentation of default networks and default
network events:
- stop logging events for default network transitions,
but instead consistently log one event per continuous segment
when one given network was the default, including logging an
event for when there is no default network.
- keep a separate rolling buffer of DefaultNetworkEvent for
dumpsys and bug reports.
These changes allow to simplify post aggregation of default network
event metrics by removing any need to do time series processing.
Instead, metrics and counters can be implemented withouth any ambiguity
by following the recipe:
% of x = sum(duration | x = true) / sum (all durations)
where x can be various conditions such as:
- the default network was validated
- the default network was WiFi
- the default network was IPv6
- there was no default network
- ...
Most importantly, this new logging scheme allows to measure much more
reliably:
- the % of the time that a device had Internet, in the sense that the
default network was validated.
- the time transitions between default networks, keyed by previous and
new transports/link layer, which allows to derive wakelock durations
and wakelock power costs from default network switches.
This patch also simplifies the dumpsys interface of the connmetrics
service and reduces the commands to three:
- "flush" for metrics upload.
- "proto" for printing buffered event in text proto format.
- "list" for listing all events and statistics.

The "roaming" state of a network really belongs on NetworkCapabilities
instead of being published through NetworkInfo.isRoaming(). One major
reason is to support developers creating NetworkRequests for a
non-roaming network.
Watch for any capability changes that network statistics are
interested in (either metered or roaming) and notify it to perform
an update pass; fixes bug where we previously only triggered on
roaming changes.
Fix bug in VPNs where metered/roaming capabilities of underlying
networks weren't being propagated; this was probably preventing
some jobs from running over unmetered networks, and causing other
jobs to run over roaming networks! Also passes along link bandwidth
information from underlying networks, and propegates any changes
to underlying networks.
Fix race condition by reading prevNc inside lock. Utility methods
correctly calculate min/max link bandwidth values.

(cherry picked from commit c57a01c166)
Always-on VPN is a feature introduced in N. Since then, all VPN apps
targeting N+ are assumed to support the feature, and the user or the DPC
can turn on / off always-on for any such VPN app. However, a few VPN
apps are not designed to support the always-on feature. Enabling
always-on for these apps will result in undefined behavior and confusing
"Always-on VPN disconnected" notification.
This feature provides a new manifest meta-data field through which a VPN
app can opt out of the always-on feature explicitly. This will stop the
always-on feature from being enabled for the app, both by the user and
by the DPC, and will clear its existing always-on state.
A @hide API is provided to check whether an app supports always-on VPN.
Documentation is updated to reflect the behavior change.
