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.

Send netlink request over fd for offload config before
completing init sequence. Provides existing conntrack
entries to IPA. Resolves issue where there are NAT
misses in IPA due to IPA only having the conntrack
entries added after tethering starts.

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.

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.
