In some networks, network validation may only get success
result for http probe but fail result for https probe.
For this kind of network, it may still work at some websites
or apps, but user didn't know about that. In order to fix this
issue, we will check if network has partial connectivity and
notify user to make a choice if they want to use this partial
connectivity or not.

In PT17, for security of the patch these two constants have been
switched from boolean to enum values. While this is nice for making
sure a patch is correct, it's also pretty wasteful. Now that it's
certain that the values of these fields don't matter, they can be
set to logical values (as opposed to reversed as it was the case
before PT17.

This change adds the relevant JNI implementations, as well as the
implementations and NetworkAgent tracking code in the TestNetworkService.
TestNetworkService (And Manager) is designed for use exclusively in
testing code, allowing for the creation of TUN and IPsec backed networks
in test code. Specifically, this allows for testing of components such
as IP, DHCP, or DNS clients, as well as kernel features such as IPsec.
Access to the TestNetworkService will be conditioned upon the
MANAGE_TEST_NETWORKS permission that will be granted only to the Shell.
CTS will use UiAutomation.adoptShellPermissionIdentity() to gain the
ability to use this service.

NSS needed it for getting VpnInfo[], NetworkState[] and
activeLinkProperties which it used to query via ConnectivityManager.
For VpnInfo[], this was racy as NSS may ignore intermediate changes to a
VPN's underlying networks. See http://b/123961098 for more context.
It may also lead to deadlocks b/w ConnectivityService and
NetworkStatsService. See http://b/126245192 for more info.
This change will ensure that NSS is never contending on any of
ConnectivityService locks.

This change is basically a revert of http://ag/3580901.
It was made because previously VPN capabilities did not use to update
based on its underlying networks. That is no longer the case anymore.
This was previously returning meteredness on the basis of VPN's first
underlying network which is incorrect in cases such as VPN using
multiple underlying networks, or VPN that has explicitly marked itself
as metered via VpnService.Builder#setMetered API.

Currently NAT64 prefix discovery, which runs in netd, is started
by netd itself when a network is programmed with all-IPv6 DNS
servers. Unfortunately this is not correct because in many cases
we program DNS servers before the network is connected and it's
actually possible to send packets to them.
In general netd does not have enough visibility into network
lifecycle management to decide when to start and stop prefix
discovery. So move it into the framework with the rest of the
464xlat control plane.

Change-Id: I8fa051a9c216d9c05082bf7d0bbb0cbd56000162
Currently, both netd and clatd do NAT64 prefix detection, and we
start clatd on all IPv6-only networks regardless of whether netd
has detected a NAT64 prefix or not.
Instead, track the NAT64 prefix in the framework, and only start
clatd if the prefix is detected. This will allow us to remove
DNS64 detection in clatd, and pass the NAT64 prefix and the IPv6
address to clatd on the command line instead of clatd finding it
itself. That way, netd and the framework will always know how
464xlat is configured, and we'll be able to use that information
in netd.

Change-Id: Ida32d5760c5aecf7aeebef08fdb596291b2ce14a
Currently, NetworkAgentInfo keeps a Nat464Xlat object only on
networks where we're starting clatd (i.e., IPv6-only networks).
Simplify this code by making the Nat464Xlat object final and
always non-null. This allows us to use Nat464Xlat to store
information, such as the NAT64 prefix, even if the clat daemon
has not been started yet.
Also, remove the STOPPING state which waits for the interface to
be removed. Instead, when stop() is called, immediately enter the
IDLE state.
- This is necessary in order to be able to call start() again
before the interface removal notification has arrived.
- It's also arguably more correct than the current code,
because when stop() returns clatd has already terminated
(ClatdController::stopClatd calls waitpid), and thus the tun
fd is already closed and the tun interface is gone.
Also, now that Nat464Xlat objects are reused after stop(), add
test coverage for calling start() after stop, in both cases:
- The notification that the previous interface was removed
arrives before the second start().
- The notification that the previous interface was removed
arrives after the second start() but before the notification
that the second interface was added.
Also fix a couple of lint warnings.

In order to support tcp keepalive offload, some socket
options are necessary. If one of them isn't supported in
kernel, just return ERROR_HARDWARE_UNSUPPORTED to the
caller.

TCP_REPAIR_QUEUE starts from kernel 3.5
TCP_QUEUE_SEQ starts from kernel 3.5

Previously, they were only updated when underlying network set was
non-null.
This change also ensures that all the calls b/w ConnectivityService and
Vpn that leads to updating capabilities are on ConnectivityService
handler thread.
Additionally, it also ensures that capabilities are propagated after VPN
enters connected state. This was previously done from establish which
could potentially lead to race between VPN getting connected and
capabilities getting updated.
This change also updates VPN capabilities inline from
ConnectivityService handler thread. Previously, there was an additional
loop where Vpn would update capabilities via NetworkAgent thru
AsyncChannel which posts back to CS handler thread, which could
potentially lead to delays in updating VPN capabilities.
