2. Bug fix in liquid precipitation and frozen fraction - SRFLAG. This bug was producing 1.e-3 factor maller values of SRFLAG. 3. Modification to comment for precipitation in sfc_drv_ruc.F90
"to include GF updates in GSDv0beta4"

Some clean-up in sfc_drv_ruc.F90.
Sync RUC LSM code with the version used in RAP/HRRR
use of MYNN PBL. The problem: the first call to the radiation happens before the first call to MYNN PBL, therefore CLDFRA_BL=0 in the first call to mynnrad_pre, and zero values are sent to array cldcov(:,:). When cloud cover is zero, the RRTMG radiation thinks that there are no clouds at all. The erroneous cloud-free LW and SW downward radiation fluxes affect the first hour of itegration, and cause siginificant cooling in the ploar regions, and too warm land surface temperature from cloud-free SW radiation. The fix: the fist call to mynnrad_pre should be skipped, so that cloud cover - cldcov(:,:) - is not overwritten by zero values of MYNN subgrid-clouds. In this case the initial cloud cover is computed in progcld5 from initial cloud water mixing ratio, relative humidity and specific humidity in the layer. Starting with the second call to the rrtmg radiation, the MYNN subgrid clouds are used.
This commit has a fix for a problem of cloud-radiation coupling with the use of MYNN PBL.
…C LSM. Variables xlaixy and rdlai are added to the argument list of lsm_ruc_run. If rdlai=.true. in the physics namelist, then the LAI climatology will be passed into the RUC LSM and used instead of look-up table value for a given vegetation type.

This is a correction for a bug. I also removed some variables that are no longer used in the code. The amount of code changed is very minimal.
