ffb0ccd04b Add a BpfMap#clear method.
A caller can mostly already do this via forEach(), but having a
specific method is faster (since the code does not need to read
the value) and easier to use.

The semantics of this method (e.g., ignore ENOENT while deleting
a key, but throw on any other error) match those of the native
BpfMap::clear method.

4e92da06fa Dump counters in "dumpsys tethering bpf".
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

862c8a1ea0 Fix tethering doesn't turn off issue
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.

634f0a8ec1 Fix miss tracking downstream problem in PrivateAddressCoordinator
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.

This change allow tethering to pick prefix from any private address

change. Will have follow up commit to change the configuration.
