Gzip static: ranges support (ticket #2349). In contrast to on-the-fly gzipping with gzip filter, static gzipped representation as returned by gzip_static is persistent, and therefore the same binary representation is available for future requests, making it possible to use range requests. Further, if a gzipped representation is re-generated with different compression settings, it is expected to result in different ETag and different size reported in the Content-Range header, making it possible to safely use range requests anyway. As such, ranges are now allowed for files returned by gzip_static.
