The primary change is to support the use of a zip file as a storage format. Simultaneously the .nz4 support is made obsolete Use of zip requires the libzip support library, so a number of changes to the build files (Makefile.am, CMakeLists.txt) are necessary to locate and incorporate libzip. The nczarr_tests tests are also changed to add zip testing. Other changes: * Make sure distcheck leaves no files around. * Add some functions to netcdf_aux to export some functions of libnetcdf. * Add a new error NC_EFOUND as the complement of NC_EEMPTY. * Add tracing support to nclog and use it in libnczarr. * Modify the zmap interface to support the writeonce semantics of zip. * Create a new s3util.c to support a variety of S3 auxilliary functions. * EXTERNL'ize a number of functions so they can be used in s3util. * Add support for the S3 ListObjects CommonPrefixes mechanism to improve search. * Add experimental support for running nczarr X s3 tests against the actual Amazon S3 cloud.
