Add __memprof_profile_reset() interface which can be used to facilitate dumping multiple rounds of profiles from a single binary run. This closes the current file descriptor and resets the internal file descriptor to invalid (-1), which ensures the underlying writer reopens the recorded profile filename. This can be used once the client is done moving or copying a dumped profile, to prepare for reinvoking profile dumping.
