re:
The current netcdf-c release has some problems with the mingw platform
on windows. Mostly they are path issues.
Changes to support mingw+msys2:
-------------------------------
* Enable option of looking into the windows registry to find
the mingw root path. In aid of proper path handling.
* Add mingw+msys as a specific platform in configure.ac and move testing
of the platform to the front so it is available early.
* Handle mingw X libncpoco (dynamic loader) properly even though
mingw does not yet support it.
* Handle mingw X plugins properly even though mingw does not yet support it.
* Alias pwd='pwd -W' to better handle paths in shell scripts.
* Plus a number of other minor compile irritations.
* Disallow the use of multiple nc_open's on the same file for windows
(and mingw) because windows does not seem to handle these properly.
Not sure why we did not catch this earlier.
* Add mountpoint info to dpathmgr.c to help support mingw.
* Cleanup dpathmgr conversions.
Known problems:
---------------
* I have not been able to get shared libraries to work, so
plugins/filters must be disabled.
* There is some kind of problem with libcurl that I have not solved,
so all uses of libcurl (currently DAP+Byterange) must be disabled.
Misc. other fixes:
------------------
* Cleanup the relationship between ENABLE_PLUGINS and various other flags
in CMakeLists.txt and configure.ac.
* Re-arrange the TESTDIRS order in Makefile.am.
* Add pseudo-breakpoint to nclog.[ch] for debugging.
* Improve the documentation of the path manager code in ncpathmgr.h
* Add better support for relative paths in dpathmgr.c
* Default the mode args to NCfopen to include "b" (binary) for windows.
* Add optional debugging output in various places.
* Make sure that everything builds with plugins disabled.
* Fix numerous (s)printf inconsistencies betweenb the format spec
and the arguments.
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).
