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:
UPDATEME
...
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)
WakeupEvent(13:40:32.144, iface wlan0, uid 1000)
WakeupEvent(13:40:35.827, iface wlan0, uid 1000)

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.

Move all corner case logic from call sites to CompareResult's implementation,
add a constructor to directly do the comparison.

This patch ensures that subtract() between two NetworkStats object will
return a delta with no negative entries in all cases.
When the stats delta contains some negative values, there are clamped to
0. Some logging is added when this happens.
This is what's expected by NetworkStatsHistory#recordData().

For some networks such as mobile data connections, its LinkProperties
does not contain routes for the local subnet so no such route is added
to the interface's routing table. This can be problematic especially
if the device is in VPN lockdown mode where there exists high-priority
PROHIBIT routing rule which in turn blocks the network's default gateway
route from being added (next hop address hitting the prohibit rule).
We fix this by patching LinkProperties to always include direct connected routes
when they are received by ConnectivityService. This has the added advantage that
when apps get LinkProperties, they see the directly connected routes as well.

Test: Start with device with mobile data, set up ics-OpenVPN in always-on
lockdown mode. Turn off mobile data then turn it back on, observe
mobile data connectivity is restored and VPN successfully reconnects.

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.

Change the evalRequests() API to protected to allow network factory
implementations to call the API.
A use-case of the API change is for factories temporarily reject a
request since they cannot fullfill it immediately but retry it at a
later time if/when conditions change.

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.

android.net.PskKeyManager was @remove'd in Android O (API Level 26)
which means it may still be available on Android O platform, but is
not part of its public API. This commit deletes this class from
future platform versions.
The reasoning for the removal of this class is that:
1. it is incompatible with TLS 1.3, and
2. TLS-PSK cannot be exposed as a standalone primitive in a safe by
default way. There is no way for such primitive to ensure that
it is used with a shared secret which is not hard-coded into the
app or is otherwise publicly known.
Test: make
Test: Run a test app which uses PskKeyManager -- the app crashes
because the class is not found
