Dennis Heimbigner d538cf38c2 Fix nczarr-experimental to better support CMake and find AWS libraries
The primary fix is to improve CMake build support.
Specific changes include:
* CMake: Provide a better soln to locating the AWS SDK
  libraries; the new way is the preferred method as described in
  the aws-cpp-sdk documentation.
* CMake (and Automake): allow -DENABLE_S3_SDK (default off) to suppress
  looking for AWS libraries.
* CMake: add the complete set of nczarr tests
* CMake: add EXTERNL as needed to various .h files.
* Improve support for windows drive letters in paths.
* Add nczarr and s3 flags to nc-config
* For VisualStudio X nczarr, cleanup the NAN+INFINITY handling
* Convert _MSC_VER -> _WIN32 and vice versa as needed
* NCZarr - support multiple platform paths including windows, cygwin.
  mingw, etc.
* NCZarr - sort the test outputs because different platforms
  produce directory contents in different orders.

One big change concerns netcdf-c/CMakeLists.txt and netcdf-c/configure.ac.
In the current versions, it was the case that --disable-hdf5
disabled netcdf-4 (libsrc4). With nczarr, this can no longer
be the case because nczarr requires libsrc4 even if libhdf5
is disabled. So, I modified the above files to move the
format options (HDF5, NCZarr, HDF4, etc) to a single place
near the front of the files. Now it is the case that:
* Enabling any of the formats that require libsrc4
  also does an implicit --enable-netcdf4.
* --disable-netcdf4 | --disable-netcdf-4 now becomes
  and alias for --disable-hdf5.

There are probably some bugs in this change in terms of
dependencies between format options.

Problems:
* CMake S3 support is still not working for Visual Studio
* A recent issue points out that there is work to do on handling
  UTF8 filenames, but that will be addressed in a separate fix.

Notes:
* Consider converting all of our includes/.h files to use EXTERNL
