Primary changes: * Add an improved cache system to speed up performance. * Fix NCZarr to properly handle scalar variables. Misc. Related Changes: * Added unit tests for extendible hash and for the generic cache. * Add config parameter to set size of the NCZarr cache. * Add initial performance tests but leave them unused. * Add CRC64 support. * Move location of ncdumpchunks utility from /ncgen to /ncdump. * Refactor auth support. Misc. Unrelated Changes: * More cleanup of the S3 support * Add support for S3 authentication in .rc files: HTTP.S3.ACCESSID and HTTP.S3.SECRETKEY. * Remove the hashkey from the struct OBJHDR since it is never used.
