'struct timeval' will have its tv_sec value overflow on 32-bit systems
in year 2038 and beyond. This patch replaces the use of struct timeval
for computing mpi_request.TimeStamp, and instead uses ktime_t which
provides 64-bit seconds value. The timestamp computed remains
unaffected (milliseconds since Unix epoch).
