Log time between network drops -- from online to offline.
Rewrite most of metrics_daemon. Convert to low-level D-Bus API -- this
simplifies the code a little and also allows us to catch the power
state signal. I still suspect we may be abusing D-Bus a little but it
seems to work.
snanda@ -- please review the power state code specifically.
BUG=none
TEST=tested on target platform and arm-generic builds
