017bfba0d8 Protect invalid entitlement app configuration
There is a protection in Settings that Settings would gray out if
tethering requires entitlement check but the entitlement app is
invalid. Tethering resource is moved from framework to tethering
module, so Settings can not fetch entitlement app name anymore.

In this change, tethering module would check whether entitltement app
package name is exsited if entitlement check is needed. Tethering would
be not supported (Settings tethering option would be hidded) if
entitlement app is not installed.

After moving the protection into tethering module,
TetherUtil#isProvisioningNeeded is no longer needed. Because The
only use case is Settings wants to gray out tethering setting
when entitltement check is needed but entitlement app is invalid.

Add commit message here for reference:
Tethering resource configuration is move from framework to tethering
module. The resource would not be accessible from outside of tethering
module.
List the replacements of framework resources usage and intent extra:
1. R.string.config_mobile_hotspot_provision_response
    --> android.net.extra.TETHER_PROVISIONING_RESPONSE.
2. R.string.config_mobile_hotspot_provision_app_no_ui
    --> android.net.extra.TETHER_UI_PROVISIONING_APP_NAME
3. R.array.config_mobile_hotspot_provision_app
    --> android.net.extra.TETHER_SILENT_PROVISIONING_ACTION
Besides, the current active subId would put in
android.net.extra.TETHER_SUBID

Note: They are not APIs because of API freeze. Now both tethering module
and Settings define these strings independently.

7c538fa7ff [BOT.6] Make BpfCoordinator to support data limit
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.

a17cf677b5 Clean up the visibility rules for framework modules
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.

      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.

cbac8e0b63 Switch framework-tethering to use java_sdk_library
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.

cd309138ce Adjust TTL for ipv6 tethering
If upstream is cellular, set the TTL in Router Advertisements to
"network-set TTL - 1" for carrier requirement. For other non-cellular
upstream, set TTL as "network-set TTL + 1" to preventing arbitrary
distinction between tethered and untethered traffic.

Bug: 154869719

Original-Change: https://android-review.googlesource.com/1288503

Fix TetheringServiceTest test WRITE_SETTINGS permission failure

AdoptShellPermissionIdentity can not pass permission check by
Settings#checkAndNoteWriteSettingsOperation. It would compare the caller
uid and its package name. See error below:
1. java.lang.SecurityException:
Specified package com.android.shell under uid 10239 but it is really 2000
2. java.lang.SecurityException:
uid 10245 does not have android.permission.UPDATE_APP_OPS_STATS.

Override the method and test if caller hold WRITE_SETTINGS directly.

c96e106d68 Make members final in TetheringService
1. Move isTetheringSupport logic from TetheringService to Tethering.
2. Small readability improvement in TetheringTest. Also change
config_tether_upstream_automatic from false to true in TetheringTest.
So TetheringTests would default run automatic select upstream flow
instead of selecting by legacy perferred network type list.
