re: https://github.com/Unidata/netcdf-c/issues/2189 Compression of a variable whose type is variable length fails for all current filters. This is because at some point, the compression buffer will contain pointers to data instead of the actual data. Compression of pointers of course is meaningless. The PR changes the behavior of nc_def_var_filter so that it will fail with error NC_EFILTER if an attempt is made to add a filter to a variable whose type is variable-length. A variable is variable-length if it is of type string or VLEN or transitively (via a compound type) contains a string or VLEN. Also added a test case for this. ## Misc Changes 1. Turn off a number of debugging statements
