The flag allows overriding the value of config_tether_upstream_automatic
on released R devices, as issues have been found on devices where an
overlay was used to set it to false.
The flag is only usable on R devices, as S devices can either not set
the setting to false, or fix the underlying issues.

This CL adds the counters collected by the tethering programs to
the output of "dumpsys tethering bpf". The counter names are
fetched by JNI code at startup and then read by the debugging
code on demand.
Example from my device:
Forwarding errors:
TCP_CONTROL_PACKET: 67
NON_GLOBAL_SRC: 13
NON_GLOBAL_DST: 17
LOCAL_SRC_DST: 7

- Add methods to start and stop IPv6 forwarding upstream
- Populate the upstream IPv6 map when the first rule for any
upstream/downstream pair is created.
- Clear the upstream IPv6 map when the last rule for any
upstream/downstream pair is deleted.

* changes:
[NFCT.TETHER.6] Migrate tetherOffloadGetAndClearStats from netd to mainline
[NFCT.TETHER.5] Migrate tetherOffloadSetInterfaceQuota from netd to mainline
This allows for better separation of test vs production code:
we will add more test maps and programs here later.

BT tethering is the only user of #tether and #untether API.
Enable BT tethering may fail by race between interface status change
and #tether call. In starting BT tethering flow, tethering may receive
pan interface DOWN and UP then PanService call #tether to request for
processing its pan interface. Tethering put interface status change
event into handler queue but it process #tether and #unether calls
right away without order them by queue. It makes tethering handle
binder call #tether before pan interface DOWN even DOWN event arrived
eailer. This cause BT tethering bring down by interface DOWN event
unexpectedly. Although this still can't fix all the race cases of
tethering, but at lesat this could fix the race mentioned above.

mForwardedDownstreams is the set of downstreams who wanted upstream.
In other word, it don't contains localOnly tethering(e.g. local only
hotspot, wifi p2p tethering). Changing the list from mForwardedDownstreams
to mNotifyList make both tethered and localOnly tethering have connected
clients callback.

When user restriction turns on, all tethering functions should
be disabled. But tethering functions still work after
restrication is on. Because tethering request would be removed
from mActiveTetheringRequests after starting tethering that
will result in Tethering#isTetheringActive() always returns
false. Thus, update the design to check tethered interface to
ensure that any of tethering function is working.

The downstream do not be tracked if PrivateAddressCoordinator just
return cached address. Then, PrivateAddressCoordinator would not notify
that downstream if conflict happen.
Also remove the null check in getDownstreamPrefix because:
- An IpServer is only added to mDownstreams by requestDownstreamAddress.
- That method will only add the IpServer to mDownstreams if it has an
IPv4 address.
- As soon as that method returns, the IpServer sets mIpv4Address to the
address that was returned.
- When an IpServer is torn down, mIpv4Address is set to null after
releaseDownstream is called.
So it should never be possible for this to return null.

Currently tethering only pick prefix from 192.168.0.0/16. There is no
aviable tethering address if the upstream address is 192.168.x.y/16.
This change allow tethering to pick prefix from any private address
rnages. Now it still pick from 192.168.0.0/16 only to avoid behavior
change. Will have follow up commit to change the configuration.
