NetCDF _FillValue bug is now fixed: eventually remove work-around code
The NetCDF _FillValue bug (upstream bug report: https://bugtracking.unidata.ucar.edu/browse/NCF-187) was fixed in source on 2015-04-02. The current NetCDF version (18.104.22.168), released in February 2015, is the last with this bug.
One way to deal with this safely would be to wait a few NetCDF release cycles, say until NetCDF-4.4 is well established in major Linux distributions, and then require this version in FindNETCDF.cmake.
Fix strided reading of large netcdf files.
netCDF bug 187 is still alive at netcdf-4.3
Implement the trick of renaming the _FillValue as suggested by NCF-133 to work-around the long lasting netCDF bug NCF-187
Add reminder to remove code.
