In order to get the tcp_info via netlink socket from kernel,
NetworkStack needs to use netlink class to pack and parse the
InetDiagReq. Current design hardcodes ididag_ext field in
InetDiagReqV2. The structure is also not allowed to take null
id to not to specify certain socket. Update the constructor and
backward support exising constructor.

Add unit tests to verify that bug has been fixed.
Re-enable testGetConnectionOwnerUid() unit tests in presubmit. These
were disabled due to test flakiness caused by expected failures passing
as a result of other sockets on the system. This is fixed by checking
that failures do not have the UID of the calling process instead of
INVALID_UID since previously some Qualcomm telephony sockets were
causing lookup successes.

The AIDLs and ipmemorystore-client were already statically linked
libraries, so their location in the source tree does not change anything
(they were already built into the NetworkStack module and the
framework). It makes more sense to have them in the NetworkStack module
folder however, as changes to these files will be released with the same
cadence as the module, not the framework.

Refactor NetworkStackClient class to move the module service binding &
network stack process death monitoring to a separate class. This class
will only instantiated in the SystemServer process.
The new class |SystemServerToNetworkStackConnector| will be used from
the client classes corresponding to each module running on the network
stack process (NetworkStackClient, WifiStackClient, etc)
This has 2 main advantages:
a) Reduces code duplication (Otherwise the various Client classes need
to replicate the service bindding & process death monitoring).
b) Central crash recovery for the network stack process (Otherwise the
various Client classes will trigger multiple recovery for a single
network stack process crash).

Tactical, minimal fix to make sure the DhcpServer is stopped when
disabling tethering. The current code may throw if the interface is gone
when calling mNMService.setInterfaceConfig() on teardown. Make sure DHCP
is stopped regardless of what happens.
A longer term fix will be to figure out the right flow to teardown the
interface and avoid errors on setInterfaceConfig().

DeviceConfig API is not yet submitted. Use Settings.Global instead, to
still allow writing tests against AOSP code (a test would try to use
adb shell device_config, and fallback to adb shell settings).
This is not merged anywhere else, the merged-in is here to ensure this
does not end up in branches that use DeviceConfig. This change should be

since it is not in framework. Moves NattKeepalivePacketData to
framework to make it can be utilized by telephony.

is misinterpreted by KeepaliveTracker that start keepalive is
failing.

The previous model could have impact on boot time to read/write from/to
disk, and could potentially fail in some scenarios where the device does
full reboots instead of framework restarts.
The current design most simply avoids crashing in the first 30mins after
a full reboot, and optimistically checks the wall clock to rate-limit
the crashes to every 6h.

Instead of always crashing on userdebug builds, do the following on all
builds:
- If the device did not observe a NetworkStack crash in the last 6h
crash the system server. This is to handle spurious crashes of the
NetworkStack, so that the system can recover instead of staying
without connectivity.
- Otherwise, the device has had a recent crash. Notify the listeners
(watchdog listener to be added) that something is seriously wrong,
but do not crash to avoid bootlooping the device. This allows the
watchdog to do its job, and avoids bricking the device in
situations where the user could need to make emergency calls.

Currently, strict mode private DNS does not work on VPNs because
NetworkMonitor does not validate VPNs. When a VPN connects, it
immediately transitions to ValidatedState, skipping private DNS
hostname resolution.
This change makes NetworkMonitor perform private DNS hostname
resolution and evaluation even on VPNs.
In order to ensure that the system always immediately switches to
the VPN as soon as it connects, remove the unvalidated penalty
for VPN networks. This ensures that the VPN score is always 101
and the VPN always outscores other networks as soon as it
connects. Previously, it would only outscore other networks
when no-op validation completed.
