This patch removes the call to runWithScissors() in
OffloadController#getTetherStats() that was causing a deadlock when
NetworkStatsService would be polled for stats in certain threading
contexts.
Instead of trying to query the tethering offload HAL synchronously all
the time, this patch:
- changes getTetherStats() to only call into the offload HAL when it
detects that it is called on the same thread as the Tethering handler
thread.
- changes the map of interface to accumulated tethering forwarded stats
to be concurrent.
This makes stats reading from getTetherStats() eventually consistent.
From the point of view of getTetherStats(), it preserves the guarantees
that tethering stats are monotonically increasing, and also guarantees
no tearing between rx bytes and tx bytes.

Currently, if setting a data limit fails, we completely stop
offload in order to avoid data overages. However, the next thing
we do is try to fetch the stats and crash, because once offload
is stopped all our local state is cleared.
Fix this by fetching stats before we stop offload.

Currently, we only count add tethering traffic to per-UID
stats, but not to total data usage (i.e., dev and XT stats). This
is correct for software tethering, because all software forwarded
packets are already included in interface counters, but it is
incorrect for hardware offload, because such packets do not
increment interface counters.
To fix this:
1. Add an argument to ITetheringStatsProvider#getTetherStats to
indicate whether per-UID stats are requested. For clarity,
define integer constants STATS_PER_IFACE and STATS_PER_UID
to represent these operations.
2. Make NetdTetheringStatsProvider return stats only if per-UID
stats are requested. (Otherwise tethering traffic would be
double-counted).
3. Make OffloadController's stats provider return the same
stats regardless of whether per-UID stats were requested or
not.
4. Make NetworkStatsService add non-per-UID tethering stats to
the dev and XT snapshots. The per-UID snapshots were already
correctly adding in per-UID stats.

This patch corrects a regression added by commit fb2609d3ee that did
not take into account the case of multiple notifications shown for a
single network id. Given how network notifications are triggered, it can
happen that NO_INTERNET and SIGN_IN notifications are both triggered for
the same network when captive portal detection is slow.
Contrary to the situation before commit fb2609d3ee, a notification
priority order is introduced so that SIGN_IN always overrides
NO_INTERNET, and NO_INTERNET is ignored if SIGN_IN is already present.

Make tethering offload register an ITetheringStatsProvider and

Currently we fetch stats in the following cases:
1. Just after changing upstreams, we fetch stats from the
previous upstream.
2. When we are polled by NetworkStatsService.

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.

This patch allows to use TYPE_NONE for the legacy network type variable
of NetworkInfo. This usage is "safe" with respect to legacy APIs using
network types as most of them already returns null or do nothing for
TYPE_NONE.
Of the existing APIs in ConnectivityManager that accept a network type
argument, those which were already returning null or doing nothing for
TYPE_NONE are:
getNetworkInfo(int)
getNetworkForType(int)
stopUsingNetworkFeature(int, String)
networkCapabilitiesForType(int)
requestRouteToHostAddress(int, InetAddress)
reportInetCondition(int, int)
isNetworkSupported(int)
getLinkProperties(int)
Only setProvisioningNotificationVisible needs an additional guard
against TYPE_NONE.
