For soil moisture streams apply over both nat-veg and crop.

This is answer changing.

Specific notes

Contributors other than yourself, if any:

CTSM Issues Fixed (include github issue #): #175, #817, #832 #833

Fixes #817 -- Have clm4_5 use the same ndep file as clm5_0 for 1850
Fixes #175 -- Have clm4_5 use the same settings for urbantv years as clm5_0
Fixes #832 -- don't override with missing value, let the model set it
Fixes #833 -- time interpolation of soilm causes bad values for some missing points

Are answers expected to change (and if so in what way)? Yes!

prescribed soil moisture changes, so that grid points that are missing on the input dataset, just run CLM normally, time interpolation might show that more points are missing, and prescribed soil moisture is also done for crops.

For clm4_5, the same ndep file is used for 1850 as for clm5_0, and same settings for urbantv are now used as well (rather than present day).

Any User Interface Changes (namelist or namelist defaults changes)? Yes namelist defaults

clm4_5 defaults for ndep and urbantv years mirror clm5_0

Testing performed, if any: regular, running standard testing on cheyenne and izumi
