re: https://github.com/Unidata/netcdf-c/issues/1693 1. Add functions to libdispatch/dnotnc4.c to support dispatch table operations that should work for any dispatch table, even if they do not do anything. Functions such as nc_inq_var_filter. 2. Modify selected dispatch tables to utilize the noop functions. 3. Extend nc_test/tst_formats.c to test. This is an extension of Ed's work to do this for chunking and deflate and szip. See PRs https://github.com/Unidata/netcdf-c/pull/1697 and https://github.com/Unidata/netcdf-c/pull/1692 As a side effect, elide libdispatch/dnotnc3.c since it is no longer used.
