Update GEFS branch to current production (#333)

* Reset to zero coupling arrays for accumulated snow,
large scale rain, and convective rain at the end of
each coupling step if coupling with chemistry model.

* Properly set kind type of literal constants.

* Initialize to zero canopy resistance output variable
in noah/osu land-surface model subdriver.

* Re-implement radiation diagnostic output involving spectral
band layer cloud optical depths (0.55 and 10 mu channels)
to prevent floating invalid errors due to uninitialized
optical depth arrays.

* Reset to zero instantaneous total moisture tendency
coupling array at the beginning of each coupling step
if coupled with chemistry model or legacy gocart.

* Correctly reset dqdt array when coupled with chemistry model.

* add capability to output restart files at specified time only

* Outout random patterns for each restart time, by setting fhstoch=restart_interval

Change-Id: Icee8f7b9cd6c32bf4d225c6f90712aee1a021668

* Add condition fhstoch >=0 for writing out random patterns

Change-Id: I61f70d94fd170d7f42a13369198eefcea7602309

* change other_restart_time to be only relative to intial time

Change-Id: I9eda1f1cb323b913e282f0530d24fc7112beff68

* change output directory of stochastic physics random pattern files
