This patch defines a new WakeupStats event in ipconnectivity.proto and
populates these events from the NFLOG wakeup events stored in
NetdEventListenerService.
There is one WakeupStats object per known interface on which ingress
packets arrive and may wake the system up.
Example from $ adb shell dumpsys connmetrics list:
...
WakeupStats(wlan0, total: 58, root: 0, system: 3, apps: 38, non-apps: 0, unrouted: 17, 6111s)
WakeupEvent(13:36:31.686, iface wlan0, uid -1)
WakeupEvent(13:38:50.846, iface wlan0, uid -1)
WakeupEvent(13:39:16.676, iface wlan0, uid 10065)

This patch stores NFLOG packet wakeup events sent by Netd to the system
server into a ring buffer inside NetdEventListenerService. The content
of this buffer is accessible by $ dumpsys connmetrics or $ dumpsys
connmetrics list, and is added to bug reports.
The wakeup event buffer stores currently uid and timestamps.

When a carrier provides an "anchor" of data usage at a specific
moment in time, augment the network statistics used by warning/limit
thresholds and Settings UI. For example, if the OS measured 500MB
of usage, but the carrier says only 400MB has been used, we "squish"
down the OS measured usage to match that anchor.
Callers using the hidden API will have their data augmented by
default, and the public API offers a way to opt-into augmentation.
Thorough testing to verify behavior.

This patch adds a layer of asynchonicity to the NetworkBaseObserver
callbacks implemented by Nat464Xlat in order to allow these callbacks
to run on the main ConnectivityService handler.
This allows to run interfaceLinkStateChanged and interfaceRemoved
callbacks in the same thread context as other Nat464Xlat methods and
solves the following issues:
- NPE risk due to race between fixupLinkProperties called on the
ConnectivityService thread and interfaceRemoved called as a
callback by NetworkManagementService.
- stale LinkProperties reads in both callbacks not called on
ConnectivityService handler.
- removes the race between stop() and interfaceRemoved().
This patch also:
- removes/simplifies comments related to the threading
model which are no obsolete.
- extract clatd management logic from ConnectivityService into
NetworkAgentInfo

This patch does some cleanup of Nat464Xlat internal state guards
against the Nat464Xlat state Idle | Started | Running, which reduces
code nesting.
It also replaces introspection of internal state for distinguishing
between different stages in 464xlat lifecycle with an enum explicitly
introducing these three Idle | Started | Running states.

This patch does some minor refactoring of clat starting/stopping code:
- remove unused LinkProperties arguments in updateClat
- remove unused Context argument in Nat464Xlat ctor
- introduce ensureClatIsStarted and ensureClatIsStopped methods and
simplify updateClat
- add clatd to NetworkAgentInfo toString() method
- clarify some comments
This changes prepare for moving BaseNetworkObserver callbacks to
ConnectivityService.

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.

Also moving relevant test files into tests/net as part of runtest
framworks-net.
Also removes testHashCode in LinkAddress() because this test relies on
the assumption that hashCode() is stable across releases or jdk
versions, which is absolutely not true.
This creates maintenance work for little benefit since hashCode is
already tested as part of the equality test.
For instance this test is now broken because hashing for InetAddress
changed.

This patch loosens the validation checks when a NetworkAgent updates it
NetworkCapabilities: instead of checking that capabilities labeled as
"immutable" stay identical across updates, it is now accepted to change
immutable capabilities in a way that the new NetworkCapabilities
satisfies the old NetworkCapabilities.
This allows a NetworkAgent to update itself in order to match more
requests, but will still catch NetworkAgents that sends degradation
updates causing potentially requests to not match anymore.

which is always more correct than doing so on a Binder thread.

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 patch corrects a regression added by commit 51727428fc 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 51727428fc, 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.
