use custom Parcel format to pull data

When statsd pulls data from StatsCompanionService, the data is put into
log_msg format on java side and expanded into LogEvent on cpp side.
There is a lot of dependency on log_msg and liblog to add new types.
There is pending bug to rewrite thta part of the code in statsd to
completely rid the legacy of logd and liblog. But that may not happen
soon.

Now we can support new storage type.
Also no need to specify number of fields in StatsLogEventWrapper cstr,
which is a source of bug in P.
