    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
