Merge of r4967: ngx_write_fd() and ngx_read_fd() errors handling. The ngx_write_fd() and ngx_read_fd() functions return -1 in case of error, so the incorrect comparison with NGX_FILE_ERROR (which is 0 on windows platforms) might result in inaccurate error message in the error log. Also the ngx_errno global variable is being set only if the returned value is -1.
