Description

In ice thermodynamics there are several small bugs. In particular:

1) one can recreate ice by snow-ice formation eventhough ice has previously melted if there is still snow. It does not happen often but it needs to be corrected.

2) in case sst > 0, it can happen that ice enthalpy becomes (very) slightly negative because the enthalpy of sea water entrapped into the ice during snow-ice formation is negative. Again, it does not happen often and we are talking about 1.e-15 J/m2 here but it is not clean.

These bugs will be corrected once I will introduce the multiple snow layers (ticket #2573)

4.0-HEAD: fix bugs and defects related to tickets #2573 #2575 #2576 #2578. Sette passed and those fixes are now in the trunk, so unless there is a tricky trick somewhere, everything should be fine.

multiple adds refering to tickets #2573 #2575 #2576. It concerns small bugs corrections for having a perfectly conservative sea-ice system, plus the removal of restriction on snow layers (one can have several layers in the snow now), plus a bug fix in very peculiar situation where ocean is always supercool
