The BPF tethering coordinator listens to the forwarding rule
changes for updating data limit which is applied in the following
conditions.
- After adding the first rule on a given upstream, add data limit.
- After removing the last rule on a given upstream, clear data limit.
- The service applies a new data limit on current upstream.
The reason for relying on rule changes is because the Tethering and
IpServer objects have multi-internal state machines. It is hard to
synchronize all of their states.
Note that the data limit cleanup for stopping or switching upstream
relies on offload rules are all removed as well.

Currently tethering notification is sending a pending intent for
redirecting user to tether settings page. However, this intent
is implicit that only create with
Settings.ACTION_TETHER_SETTINGS. For security reasons, this
intetnt should specify an explicit component to be delivered to.
Thus, specify the settings package name to this intent.

Reduce advertised ipv6 mtu by 16 to fit ethernet header
This is a temporary hack to workaround the inability of current
kernel's ebpf bpf_skb_change_mode() function to prefix a 14-byte
ethernet header on to a packet without going over the upstream
(source, rawip) interface's mtu *before* we bpf_redirect() to
the downstream (destination, ethernet) interface.

(cherry picked from adac7d2cc3)
Switching from java_library to java_sdk_library switched the meaning
of the module name from referring to the implementation library to
referring to the stubs. This change updates the visibility rules to
reflect that new meaning.
Visibility rules that were previously set for the java_library have
been moved to the impl_library_visibility property and the special
//visibility:override value has been prepended to prevent it from
inheriting the values from the visibility property.
Visibility rules set for the stubs (via stubs_library_visibility)
property have been moved to the visibility property.

The names of the individual modules do not quite follow the pattern
that java_sdk_library uses so this temporarily sets the following:
naming_scheme: "frameworks-modules"
That causes java_sdk_library to use a naming scheme that matches the
one used by the individual modules of this. It will be cleaned up
later.
Part of the purpose of the java_sdk_library is to hide the
implementation code and force users of the library to depend on stubs
for a well defined API. Ideally, it would allow access to the
implementation in those cases where it is safe, e.g. from within the
same APEX, or from tests for the implementation. Unfortunately, due to
limitations in the build it does not yet have enough information to
make that decision correctly which means that any code that needs to
compile against the implementation is broken which would prevent us
from converting the module to java_sdk_library.
However, the only way to provide the additional information to allow
the implementation to be correctly exposed is to convert the modules
to java_sdk_library; a cycle.
In order to break that cycle the java_sdk_library creates a special
<module>.impl target which is used directly by tests and any other code
that needs it. Once all the modules have been converted to a
java_sdk_library then we can resolve the limitations in the build and
remove the direct references to <module>.impl.
