SubscriptionManager.setSubscriptionOverrideUnmetered() has been updated
to add NET_CAPABILITY_TEMPORARILY_NOT_METERED instead of
NET_CAPABILITY_NOT_METERED. So, we can't rely on that for changing the
meteredness.

* changes:
Accept both pre-S and post-S errors in getConnectionOwnerUid.
Add CTS coverage for VpnTransportInfo.
Add test coverage for registerSystemDefaultNetworkCallback.
On R and below, when an app that is not the active VPN app calls
getConnectionOwnerUid, a SecurityException is thrown. On S and
above, the method just returns INVALID_UID, which is what would
happen if the app was the active VPN app but was not authorized
to find that particular socket.
Accept both behaviours.

Test: atest HostsideVpnTests#testGetConnectionOwnerUidSecurity passes on R and S

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
Test: manual (debug-only code)

Currently, the dump methods open BpfMap objects and never close
them. This leaks filedescriptors, and if dump is called often
enough, will crash the networkstack process.
Fix this by using try-with-resources statements that
automatically close the map when exiting the try block.
Change the signature of BpfMap#close from "throws Exception" to
"throws ErrnoException" since it does not throw any other type
of checked exceptions.
Test: "lsof | grep network_st" while running "dumpsys tethering bpf" in a loop

Currently, debugging the tethering programs is not easy because
in case of any failure they simply return TC_ACT_OK. This CL adds
a number of counters that the program can increment in the case
of interesting events such as malformed packets.
At the moment the counters are stored in a global tethering error
map, which is an ARRAY map of 32-bit counters. This should not
take up much space because there are only a dozen of these.
We might not need all of these counters. In future CLs we can
reduce the number of counters, or perhaps move them to a map of
maps so as to have separate counters on a per-interface basis.

This provides a place to store common definitions that can be
used by both the programs and by JNI code in the tethering
module.
Over time much of the tethering-specific code in bpf_shared.h
could move here.
