vim-patch:7.4.2017

Problem:  When there are many errors adding them to the quickfix list takes
          a long time.
Solution: Add BLN_NOOPT.  Don't call buf_valid() in buf_copy_options().
          Remember the last file name used.  When going through the buffer
          list start from the end of the list.  Only call buf_valid() when
          autocommands were executed.
