On some devices, support for TYPE_ETHERNET is not specified in
the networkAttributes config resource, even though the device is
capable of supporting Ethernet (e.g., via USB host adapters).
This leads to Ethernet working but various connectivity APIs
behaving as if it was not - for example, no CONNECTIVITY_ACTION
broadcasts will be issues when it connects or disconnects.
Ensure that ConnectivityService always treats Ethernet as
available if the service is running. Currently the service is
started if the device supports FEATURE_ETHERNET or
FEATURE_USB_HOST.

This patch implements an outstanding TODO in ConnectivityService to add
synchronization over the map of network request ids to network agent
info objects.
This structure is accessed from multiple threads:
- Binder thread on public aidl methods, most notably via
getDefaultNetwork().
- Internal handler.
This leads to many race conditions that can crash the system server and
reboot the phone if getDefaultNetwork() is called on a Binder thread to
service a public ConnectivityManager api while the default network state
is being updated on the internal handler after losing the default
network.

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.

(cherry picked from commit 729f0b476d)
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.

Change-Id: I4d6bb43110916b440819813b478523546ac5570e
This patch relays the NetworkBaseObserver notifications about nat
464xlat stacked interfaces onto the ConnectivityService handler.
This allows to process interface up and down notifications in the
same thread context and eliminates several races:
- NPE risk due to race between fixupLinkProperties called on
ConnectivityService thread and interfaceRemoved called on
NetworkManagementService thread.
- stale LinkProperties pointer reads in both NetworkBaseObserver
callbacks not called on ConnectivityService handler.
- removes the race between stop() and interfaceRemoved().
- removes superfluous LinkProperties notifications when stop() is
called before the stacked interface goes up.
The teardown procedure logic common to stop() and interfaceRemoved() is
put into enterStoppedState() and enterIdleState().
This allows to distinguish and correctly handle the following teardown
scenarios:
- an IPv4 appears -> ConnectivityService calls Nat464Xlat#stop()
-> Nat464Xlat calls stopClatd
-> clatd stops
-> if the stacked interface was up, it is removed
-> Nat464Xlat#interfaceRemoved() is triggered and
a LinkProperties update is sent.
- network disconnects -> ConnectivityService calls Nat464Xlat#stop()
-> Nat464Xlat calls stopClatd
-> clatd stops
-> if the stacked interface was up, it is removed
-> Nat464Xlat#interfaceRemoved() is triggered and
a LinkProperties update is sent.
- clatd crashes or exit -> Nat464Xlat#interfaceRemoved() is triggered
-> Nat464Xlat unregisters itself as a network
observer
-> ConnectivityService is updated about the
stacked interface missing, and restarts
Nat464Xlat if needed.
Note that the first two scenarios have two cases: stop() can be called
before the notification for the stacked interface going up (STARTED), or
after (RUNNING). In the first case, Nat464Xlat must unregister
immediately as a network observer to avoid leaks.
This patch also:
- removes/simplifies comments related to the threading model which
are no obsolete.
- extract clatd management logic from ConnectivityService into
NetworkAgentInfo
- add new unit tests where there was none before.

This allows to run interfaceLinkStateChanged and interfaceRemoved

- NPE risk due to race between fixupLinkProperties called on the
ConnectivityService thread and interfaceRemoved called as a

- stale LinkProperties reads in both callbacks not called on

immutable capabilities in a way that the new 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.
