e0f34033e0 Don't unnecessarily reevaluate tethering provisioning
Registering for carrier config changes can deliver a sticky broadcast
and can cause Tethering to think something has changed and reevaluate
provisioning status, even though this has been checked before it
entered tethering mode alive state.

Additionally, move the provisioning_app{,no_ui} resources into the
TetheringConfiguration, if for no other reason than now we can log
it in .toString().

Test: as follows
    - built
    - flashed
    - booted
    - runtest frameworks-net passes
    - manual USB tethering toward WiFi works

7301aa4140 Trigger NetworkCallback events when private DNS usage has changed.
Relies on events sent from netd in aosp/578162.

Test: Added tests to ConnectivityServiceTest. Added a new test
class DnsManagerTest. Built a simple app that appears to
receive onLinkProperties events correctly upon manual changes
to the private DNS settings on a Pixel.

465ff3a0c1 Refactor isTetheringSupported() calls
Tethering currently wants access to complex isTetheringSupported
logic that is only available in ConnectivityService. Instead of
trying to access that via ConnectivityManager, pass this capability
in to Tethering directly, in the TetheringDependencies object.

Also:
    - ConnectivityManager is only a source of static constants now,
      so "import static" all the constants that are actually used.

    - built

e0d26f66b0 Limit the number of routes for performance
In evaluating whether "most" of the addressing space is
covered, the list of routes are obtained from a third-party
app, so it's possbile the system service stalls unless
some limit is enforced on how much work it has to do.
This change limits the number of routes to 400, as determined
by time measurement on various devices.

22795302be Check mOwnedByTransform to avoid DELSA on SPI
The owned by transform flag prevents the removal
of an SPI from accidentally deleting an associated
SA in the kernel. That flag wasn't actually being
checked, so deleting an SPI would result in the
transform being removed.

The existing code already guarantees that the SA is
deleted when the transform is deleted

804b8fb968 Publish FOREGROUND and add NOT_SUSPENDED capabilities.
NOT_SUSPENDED and FOREGROUND are capabilities that need to
be public so as to reach feature parity with what information
can be gotten through the use of CONNECTIVITY_ACTION and
synchronous calls to ConnectivityManager. This change makes
them public, and wires up the NOT_SUSPENDED capability.
This deprecates in effect the old onSuspended and onResumed
callbacks, but these have never been public.

This also converts the onAvailable path from a multiple
binder call design to a simpler, single binder call. This
is only for internal convenience

f19db37409 Send null UIDs to apps instead of single-uid lists.
Prior to this change ConnectivityManager used to patch in the UID
of the requesting app inside the NetworkCapabilities sent to it.
The rationale was that the app may not know what other apps may
use the network, so the view it should have of the network should
always say the network only applies to that app.

But this has an unfortunate side effect : apps can't match the
received network against a default NetworkCapabilities. Ostensibly
this only applies to the system because all involved calls are
@hide, but still : system code would get some NetworkCapabilities,
for example using networkCapabilitiesForType, and then try to
match the capabilities of an available network using
satisfiedByNetworkCapabilities. Because the passed network is
declared to only apply to one's own UID and the UIDs of the
NetworkCapabilities are set to null meaning "I need this network
to apply to all UIDs", the answer will be "false".

While this is WAI in a sense, it is very counter-intuitive that
code trying to match a network would be required to patch in its
own UIDs.
There are three ways of fixing this :
1. Require all apps to do the above. It's correct, but it's
   cumbersome and counterintuitive. Multiple places in existing
   code needs to be fixed, Tethering is an example.
2. Write the UIDs of the caller in any NetworkCapabilities object
   that is created. This is not very practical, because it imposes
   the converse requirement on all NetworkAgents, which would then
   have to clear the UIDs before they send the capabilities to
   ConnectivityService. All NetworkAgents need to be fixed.
3. Instead of sending an object with a list of one UID to apps,
   send a null list. The drawback is that the networks nominally
   look to apps like they apply to all apps. I argue this does
   not matter ; what matters is that the UID lists do not leak.
   Clients just see a null list of UIDs (and third party can't
   even access them without using reflection). No other changes
   are required besides this two-line patch.

This patch implements 3. I believe it is the saner approach, with
both the most intuitive behavior and the best backward compatibility
characteristics, as well as the easiest change.

This does not encroach on the future plans to make the actual
UID list available to apps with NETWORK_SETTINGS.

bb16b75b67 Fix default network validation overcounting
When switching from a validated default network to a new validated
default network (typically because of a better score),
DefaultNetworkMetrics would not reset the last validation timestamp.

This would cause the new default network to have a total recorded
validation time overcounted by the validation time of the previous
default network.

The following fix should be applied downstream for consumers of
previously recorded data:

  validation_time = min validation_time, duration_time);

e93c569bd3 Prevent crash in NetworkManagementServiceTest#shutdown()
The shutdown method in NetworkManagementServiceTest was trying to close
the local socket on the test side, causing the NativeDaemonConnector
internal to NetworkManagementService to sometime crash due to the
output stream on NetworkManagementService side to throw on pending
reads.

The correct fix would be to shutdown the NativeDaemonConnector
inside NetworkManagementService and implement NetworkManagementService's
shutdown method, however there is no way to cleanly close a
NativeDaemonConnector.

Instead, this patch doesn't do any cleanup of the listening socket, the
test local socket, and its output stream. These objects' resources get
eventually collected by the system when the test process exits.
