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.

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.

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.

The CL that moved the initialization of the tethering offload
config HAL from C++ to Java caused the code not to retry
fetching the service if it is not ready when tethering is
started. This is because the C++ version of getService() retries,
but the Java version only retries if getService(true) is called.
Make the new code retry as well.
b/152430668#comment4 asserts that the fetch will be retried only
if the service is installed on the device, so the retries should
be attempted (and thus should not have any startup time impact)
on devices that do not support tethering offload.

wifi is in disabling state.
