re: https://github.com/Unidata/netcdf-c/issues/1642 Modify ncdump, nccopy, and ncgen to support the NC_COMPACT storage option. Added test cases and added description to the man pages for the utilities. 1. ncdump: For compact storage variable, print special attribute __Storage_ as ```` <var>: _Storage = "compact"; ```` 2. ncgen: parse and implement ```` <var>: _Storage = "compact"; ```` in a .cdl file 3. nccopy: Extend the chunk specification (-c flag) to support compact using the forms ```` nccopy ... -c <var>:compact and nccopy ... -c <var>:contiguous ```` Misc. other changes 1. cleanup the copy_chunking function in ncdump/nccopy.c
