Update disk space utilization together with diskstats since we will
use free space size to co-relate disk performance.

BatteryListener takes sp<> as parameter. Passing raw storaged_t ptr
to BatteryListener will cause the ptr to be freed when BatteryListener
releases the sp<>. Keep a refcount in storaged to prevent this from
happening.
Test: kill healthd while 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

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.
Test: adb shell dumpsys storaged --hours 2

Add uid_monitor class to query /proc/uid_io/stats periodically.
Add a log tag to record any UID that exceeds IO threshold.

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.
