https://github.com/Unidata/netcdf-c/issues/1168 https://github.com/Unidata/netcdf-c/issues/1163 https://github.com/Unidata/netcdf-c/issues/1162 This PR partially fixes memory leaks in the netcdf-c library, in the ncdump utility, and in some test cases. The netcdf-c library now runs memory clean with the assumption that the --disable-utilities option is used. The primary remaining problem is ncgen. Once that is fixed, I believe the netcdf-c library will run memory clean with no limitations. Notes ----------- 1. Memory checking was performed using gcc -fsanitize=address. Valgrind-based testing has yet to be performed. 2. The pnetcdf, hdf4, and examples code has not been tested. Misc. Non-leak changes 1. Make tst_diskless2 only run when netcdf4 is enabled (issue 1162) 2. Fix CmakeLists.txt to turn off logging if ENABLE_NETCDF_4 is OFF 3. Isolated all my debug scripts into a single top-level directory called debug 4. Fix some USE_NETCDF4 dependencies in nc_test and nc_test4 Makefile.am
