Each crop column should only have one patch, so by only calling these for crop columns, we can simplify things considerably.

"Throw error during namelist build if tillage is called with FATES"

Update FATES tests to double precision

This pull request updates the fates tests to set the output
precision to double precision.  The usermod fates_sp is similarly
updated.

Still won't work with use_crop false. FATES handles coarse woody debris separately, but I haven't added handling of that, so implicitly tillage just doesn't affect CWD.

Multiple active crop patches per column shouldn't be possible YET, but perhaps eventually it will be.

Add parameterization to allow excess ice in soil and subsidence

Description:
Parameterization for excess ice described in Lee et al. (2014):
http://dx.doi.org/10.1088/1748-9326/9/12/124006

This code is a modified version of code provided by Lei Cai:
https://github.com/lca041/ctsm/tree/clm5.0.dev92_exice

Works only for the nuopc driver.

Between CropPhenology()and get_tillage_multipliers(). New function DaysPastPlanting() shared from CNPhenologyMod to TillageMod.

In default configuration, there's no difference. This is setting up for the specification of this depth as a namelist parameter. Partially-tilled layers not yet allowed.

This enables unit testing of this code.

I understood zisoi to give the bottom of each layer, but it actually gives the top.
