Revised the interfaces to the myStats routine in the horizontal_regridding module to avoid segmentation faults due to inconsistent horizontal indices and array extents in global indexing mode. Rather than passing in absolute array extents to work on, an ocean grid type is now passed as an argument to myStats, with the new optional full_halo argument used to capture the case where the tracer statistics are being taken over the full data domain. The most frequently encountered problems occurred when the hard-coded debug variable in the horiz_interp_and_extrap_tracer routines are changed from false to true. When global indexing is not used, this revised work exactly as before, but when it is used with global indexing, it avoids segmentation faults that were preventing the model from running in some cases with all debugging enabled.

- It was blowing up with "forrtl: error (65): floating invalid" when accessing dz in the halo at the boundary, but just sometimes. My default layout is trouble while my testing layout of 48 cores is not.
-even for PPM advection and OBCs.
Removed allocated tests for the potentially statically allocated arrays CS%uhtr and CS%vhtr in a newly added line testing whether there are OBCs in use that would require a halo update on these arrays. Even in dynamic memory mode, these arrays are always being allocated, so these tests served no purpose, but in static memory mode they led to compile time errors. All answers are bitwise identical.

This PR got a bit mangled because I merged in an unsquashed PR which I retroactively squashed. Since it is passing all of our tests, I manually rebased this one into dev/gfdl: 0ff03ae |
