1. When Wi-Fi enabled, ap0 interface is added and IpNeighborMonitor's
start() is invoked in IpServer's constructor.
2. There's no stop for IpNeighborMonitor when IpServer stop.
3. During overnight test for Wi-Fi, networkstack is too slow to
process request due to memory leak in IpNeighborMonitor and
binder buffer is blocked causing exception.
Solution: Invoke IpNeighborMonitor.stop() in UnavailableState.enter().

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.

List the replacements of framework resources usage and intent extra:
1. R.string.config_mobile_hotspot_provision_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.

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.

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.

1. Change ArraySet usage to BitSet
2. Change mCellularUpstreamPermitted to mLastCellularUpstreamPermitted.
Before this change:
a member variable(mCellularUpstreamPermitted) is
used to check whether cellular upstream is permitted, the code must
ensure to update this variable once entitlement result is changed or the
entitlement check is triggered but does not have a result yet.
In this change:
Instead of storing the information about whether cellular is permitted in
a member variable. The information is recalculated every time when user
call isCellularUpstreamPermitted(). Now isCellularUpstreamPermitted() is
always be used to check whether cellular upstream is permitted no matter
inside or outside EntitlementManager.
This make the code be easier to maintain that we do not need to care
when mCellularUpstreamPermitted need to be updated because the
information would be recalculated every time. And the recalculation is
lock free because this is only used inside tethering while running in
the same thread.

The OEM implemented tether offload does not support
data warning since the HAL only tells the hardware about data limit
but not warning. However, to add such interface in HAL needs OEM to
comply and implement in hardware.
Thus, as a short-term solution, polls network statistics from HAL
and notify upper layer when it reaches the alert quota set by
NetworkStatsService.
Note that when CPU is sleeping, the data warning of tethering offload
will not work since the polling is also suspended.
