Sturm_vegMods + new SNICAR + SNICAR param changes w/xdrdt=5 (ctsm51_ctsm51d150_ne30pg3ne30pg3mg17_GSWP3V1_ABCDE_blk_A5BCD_1850AD)

[olyson]

Description:
Same as ctsm51_ctsm51d150_ne30pg3ne30pg3mg17_GSWP3V1_ABCDE_blk_ABCD_1850AD but with xdrdt=5 and a code mod such that the xdrdt change actually takes effect. The ABCDE_blk_ABCD simulation had xdrdt changed to 2, but it didn't take effect because of an issue in the code
Just running an AD for now.
Note that this uses ctsm5.1.dev150.

SourceMods:

src.clm/atm2lndType.F90: Add some additional history fields
src.clm/clm_varpar.F90: nlevurb=5 -> nlevurb=10
src.clm/surfrdMod.F90: Remove read of PFTDATA_MASK
src.clm/Wateratm2lndType.F90: Add some additional history fields
src.clm/SoilTemperatureMod.F90 Sturm Snow tk
src.clm/CNPhenologyMod.F90 decreasing temperature thresholds to -3C, reducing the minimum critical daylength by 25%, doubling the snow threshold (I think to 20 cm)
src.clm/controlMod.F90 remove error associated with snicar_snobc_intmix
src.clm/SnowSnicarMod.F90 set flg_snoage_scl to .true. so that xdrdt change takes effect

Extra details:
My case name lengths are out of control, so I've designated this combination simulation as ABCDE_blk_A5BCD, where the first ABCD is:
A - SturmSnowtk (implemented via src.clm/SoilTemperatureMod.F90)
B - decidphenotrig (implemented via src.clm/CNPhenologyMod.F90)
C - frootleaf (implemented via ctsm51_params.c211112.nc.ABCD_blk_A5BCD.nc)
D - FUNfracfixers (implemented via ctsm51_params.c211112.nc.ABCD_blk_A5BCD.nc)
E - new SNICAR
blk - snicar_snobc_intmix = .true. (implemented via namelist, per Issue #36 )
and the next ABCD is (per Issue #36 )
A5 - xdrdt = 5 (implemented via ctsm51_params.c211112.nc.ABCD_blk_A5BCD.nc and takes effect by code change to SnowSnicarMod.F90)
B - scvng_fct_mlt_sf = 0.5 (implemented via ctsm51_params.c211112.nc.ABCD_blk_A5BCD.nc)
C - snw_rds_refrz = 1500 (implemented via ctsm51_params.c211112.nc.ABCD_blk_A5BCD.nc)
D - fresh_snw_rds_max = 400._r8 (implemented via namelist)
