It is possible for storaged to load the same saved proto file multiple
times, for example, if system_server crashes. In this case we do not
want to fill io_history with duplicate entries. This patch elides
records for which an app+userid record already exists for the same
timestamp.

protobuf is only needed when serializing/deserializing data. Instead of
maintaining a permanent buffer in storaged object, move the container to
stack so that the buffer is released when we don't need it. In addition,
we don't need to clear the buffer before updating it.
Also added a function to clear user io history when the user is removed.

Use user_id (from app uid) to determine file location.
/data/misc_ce/<user_id>/storaged/storaged.proto
Vold notifies storaged when a user's CE area becomes available.
Then storaged restores data from the proto in that area and
combines them into IO history.
Vold also notifies storaged when the CE area is being deleted.
Storaged clears internal history about this user and deletes the
proto file.
IO perf is stored in user_0 area since it's not user related.

Change-Id: I39f923f6b09e9f2a29e9286ce02b3b3bcbfb9f94
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

comm field in task io stats string can have comma since this field
includes task arguments. As a result, splitting the string by comma
doesn't always give 13 fields. Parse the string in following way to

Second field to 12th from last -> comm
