Use proto_stat to indicate status of CE area. Before user_0 unlocks,
storaged detects CE NOT_AVAILABLE when attempting to read the proto
file. It then skips reading/writting the proto.
When user_0 logs in, vold calls onUserStart in storaged, which sets
proto_stat to AVAILABLE. At next event, storaged tries to read the
proto. If it's a success, proto_stat is changed to LOADED. After that,
storaged reads and writes proto normally.

Split binder calls into two separate services.
"storaged" service will be used by external clients, e.g. vold.
- Added stub onUserStarted/onUserStopped to prepare for moving
storaged.proto into ce area.
"storaged_pri" private service will be used by storaged cmdline,
e.g. adb shell storaged -u
- Added parcelable UidInfo for private service.
- Change format of perf history to one vector with first 3 elements
showing size of recent/daily/weekly perf history.

Record the bandwidth when writing storaged.proto to monitor system
storage performance.
The history is maintained in 3 catergories.
1. samples of last 24 hours.
2. daily average of last 7 days.
3. weekly average of last 52 weeks.
Sampling frequency of the first catergory is set to once every hour.
Storaged also flushes proto at same frequency.
The proto file is padded to reach a minimal size of 128KB. Storaged
writes 16KB at a time. Bandwidth calculation ignores time spent in
the first write and writes smaller than 16KB.
bandwidth = total size of 16KB writes / time spent in 16KB writes
Restructured the code so that storaged.cpp handles proto load/flush.
It calls individual module to sync proto with internal data
structures.
Added a cmdline argument to dump perf history.
adb shell storaged -p

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.
