Teach NetworkStats about "counter sets" coming from kernel, and use
them to track usage in foreground/background. Add AID_NET_BW_ACCT to
system_server so it can control counter sets.
Move to composite key of NetworkIdentitySet, UID, set, and tag when
recording historical usage. Persisting still clusters by identity,
since that is heaviest object.
Request async stats poll during systemReady() to bootstrap later
delta calculations. Reset kernel counters when UID removed. Update
various tests.

When an iface goes inactive, xt_qtaguid maintains historical counters
instead of discarding. Now reading and returning those values in
NetworkManagementService summary calls. Tests to verify stats are
returned.
Modify NetworkStats to include rxPackets and txPackets values, and
move to Entry to eventually hide internal storage details.

Change NMS parsing to handle extended /proc/ stats formats by pairing
values with header keys. Move TrafficStats to integer tags to match
kernel internals, and offer well-known tags for system services.
Async policy event dispatch from NPMS, and update tests to block for
event dispatch. Narrow app policy to exclude apps signed with system
key, which are usually critical.
