Jeff Sharkey e9bda1dd68 Accumulate network statistics based on deltas.
Network stats are now read out of the kernel in one sweep, instead of
reading per-UID.  We now accumulate the delta traffic between each
stats snapshot using the well-tested SamplingCounter pattern.

Since Wi-Fi and mobile traffic have different costs, track each
separately.  Avoids counting misc interfaces like loopback and
ethernet under total.
