re: https://github.com/Unidata/netcdf-c/issues/2117 re: https://github.com/Unidata/netcdf-c/issues/2119 * Modify libsrc to allow byte-range reading of netcdf-3 files in private S3 buckets; this required using the aws sdk. Also add a test case. * The aws sdk can sometimes cause problems if the Awd::ShutdownAPI function is not called. So at optional atexit() support to ensure it is called. This is disabled for Windows. * Add documentation to nczarr.md on how to build and use the aws sdk under windows. Currently it builds, but testing fails. * Switch testing from stratus to the Unidata bucket on S3. * Improve support for the s3: url protocol. * Add a s3 specific utility code file: ds3util.c * Modify NC_infermodel to attempt to read the magic number of byte-ranged files in S3. ## Misc. * Move and rename the core S3 SDK wrapper code (libnczarr/zs3sdk.cpp) to libdispatch since it now used in libsrc as well as libnczarr. * Add calls to nc_finalize in the utilities in case atexit is disabled. * Add header only json parser to the distribution rather than as a built source.
