Fix missing 'final' on some ClassWriter methods. See https://mail.ow2.org/wws/arc/asm/2011-11/msg00008.html. This might break backward binary compatibility for some users, but this is unlikely since all the other visit methods are final.

Delete the ASMifiable and Textifiable interfaces, moved to asm-deprecated. See deprecated@7c0e20d0.
