re: https://github.com/Unidata/netcdf-c/issues/1451
The situation with the various DAP (and other) remote test
servers is currently in a state of flux. For example, Unidata
admin is planning to forcibly shift the remote test server to
remotetest.unidata.ucar.edu soon. In addition, the server
test.opendap.org has shown some recent instability.
The result is that various DAP (and byterange) tests can fail
unexpectedly. This is an irritant to users and reveals nothing
about test sucess or failure.
Solve by modifying tests to report server inaccessibility and
otherwise pretend to succeed.
This puts an onus on Unidata to detect such server failures, but
will not cause users to see spurious failures. [Note. Do similar
fix for netcdf-java]. The check is:
1. export SETX=1 to cause all the shell scripts to trace
2. search the log files for the phrase "WARNING" (in upper case)
and see if it is complaining about not finding a server.
Misc. Changes
-------------
1. Added a pingurl program to see if a server was up.
2. modified some test case url targets

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
times, but returning the same ncid.
2. Separate out the dap auth tests
and make them disabled by default.
3. turn of ncdap_test/test_varm3 until
we can find a copy of coads_climatology.nc
The code that tests if a path is a url is
faulting when the url does not end in a slash
(e.g. http://thredds-tests.ucar.edu).

Solution was to do a null pointer test.
Added a test (tst_misc).
