Perf profile collection daemon.
Collects system-wide profiles via periodic invocation of
/system/bin/perf, placing the resulting data files in a destination
directory selected via config file. Behavior of the daemon, e.g how
often to profile, duration of profiling runs, etc, can also be
controlled with config file settings.
