storaged relies on batteryproperties service (healthd) to provide
charger stats. If healthd is killed, kill storaged as well. Both
will be restarted by init process anyway to restore a correct state.
Test: kill healthd when storaged is running

Sysfs data is straightforward so we don't need parsing anymore.
Also removed periodical check since data is set only once during
driver initialization. Checking at every device boot or storaged
restart should be sufficient to monitor long term status change.
Test: adb logcat -d -b events | grep storaged_emmc_info

Note starttime2 is skipped if it equals with endtime1.

This option forces storaged to generate io usage report since last
report. This is for testing purpose so that we can run some app and
get the app's IO usage right away instead of waiting an hour for next
report.

--threshold <bytes>
This skips io usage not greater than <bytes> for current report.
--time_window <secs>
This sets uid_io collection interval to <secs> for future reports.
The new interval will be ignore if it's less than 5 minutes.

1. Add a flag to report IO usage for last N hours.
2. Change interval back to 1 hour so that we have finer usage data.
3. Don't clear events after dumpsys call. Use a max buffer limit.
4. Clear old events if they're more than 5 days old or when no room
for new events.
5. Skip uids with no IO usage to save space.
6. Replace interval with a timestamp in event entry.

Storaged periodically checks the devices' disk stats and eMMC lifetime.
This information is logged to both the kernel and event log. By event
logging, the data can be aggregated by the checkin service and then
sent to Sawmill.
It also periodically traverses /proc/[pid], maintaining the I/O usage of
all tasks (all sampled tasks). The task I/O data can be reported using
the --dump option.
Storaged is booted when the device boots up and requires the permission
for reading /proc/diskstats, /proc/[pid]/io and debugfs(eMMC ext_csd).
For detailed description, please refer to go/storaged.
