re: https://github.com/Unidata/netcdf-c/issues/1373 (partial) * Mark some global constants be const to indicate to make them easier to track. * Hide direct access to the ncrc_globalstate behind a function call. * Convert dispatch tables to constants (except the user defined ones) This has some consequences in terms of function arguments needing to be marked as const also. * Remove some no longer needed global fields * Aggregate all the globals in nclog.c * Uniformly replace nc_sizevector{0,1} with NC_coord_{zero,one} * Uniformly replace nc_ptrdffvector1 with NC_stride_one * Remove some obsolete code
