    Sealevelponds branch was failing baseline comparison tests. This issue was found to be caused by the initialization of the tscale_pnd_drain parameter and has been fixed. Additionally, while fixing this issue an issue related to how sealevelponds was being initialized was discovered and fixed for the standalone driver. Those changes will need to be propagated to the other drivers. Regression tests have only been completed vs. a run1day test and so the full suite still needs to be run.

…3.2.0 (CICE-Consortium#1000)

Update Icepack to #fa56e7e387b1, needed for cce/17.0.0

Cleaned up some trailing blanks.
This is a two-line change in ice_flux.F90 (scale_fluxes) to check for the condition where aice > 0, but flwout > -puny (effectively zero). This means the cell was ice free at the beginning of the step, but non-zero at the end. It sets the outgoing longwave to the open ocean value based on the freezing temperature. This is bfb, but will change the history output of flwup and flwup_ai. Test results are coming.
… bfb (CICE-Consortium#1002)

Update Icepack to #43ead56380b, hocn and flushing velocity issue, not bfb.

See CICE-Consortium/Icepack#504
