The system API are moved to the connectivity module: add dependency on
the stubs from framework-tethering.

This only allows tethering to depend on system API defined by the
connectivity classes, not on any private code, even if they are
eventually bundled in the same APEX.

A caller can mostly already do this via forEach(), but having a
specific method is faster (since the code does not need to read
the value) and easier to use.

The semantics of this method (e.g., ignore ENOENT while deleting
a key, but throw on any other error) match those of the native
BpfMap::clear method.

In AOSP master and downstream branches, this likely works via a
transitive dependency. In mainline-prod, this doesn't work. Add
the dependency explicitly, since it makes things build everywhere
and in general it's also good practice to "include what you use".

Any PendingIntent needs to be specified about the mutability.

While ConnectivityService would put extra info such as
network or request id before broadcasting the inner intent.
The MUTABLE flag needs to be added accordingly.

The asserted capabilities change callback event took 170ms
in average to fire on cuttlefish, which causes 35% of
flakiness since the event might delay up to 500ms in practice.
Extend to 30s timeout value which is the standard value
of waiting for network callback events in CTS.

This change also ignore the test up to Android R since the API
is not available for R devices or below.

The test did not verify that mobile networks were validated before
starting, which could cause them to validate during the test and pick up
the test URLs. Verify that mobile data is validated before the test.

Also shorten test URL expiration, so in case of hard-interrupt of the
test (without calling tearDown) it does not affect other tests for a
long time.

We've backported the necessary support to all 4.14+ ACK kernels,
but we can't actually enforce that these changes will be picked
up by all devices.  Thus we can only make the full featured
implementations optional on [4.14..5.8) kernels, with a tcp-only
version for those 4.14+ devices where the full featured version
fails to load.

Note: there's still a fair bit of implementation work left
in the do_forward4() function itself.  This is really just
the skeleton.
