Gzip: fixed setting of NGX_HTTP_GZIP_BUFFERED. In r2411 setting of NGX_HTTP_GZIP_BUFFERED in c->buffered was moved from ngx_http_gzip_filter_deflate_start() to ngx_http_gzip_filter_buffer() since it was always called first. But in r2543 the "postpone_gzipping" directive was introduced, and if postponed gzipping is disabled (the default setting), ngx_http_gzip_filter_buffer() is not called at all. We must always set NGX_HTTP_GZIP_BUFFERED after the start of compression since there is always a trailer that is buffered. There are no known cases when it leads to any problem with current code. But we already had troubles in upcoming SPDY implementation.
