[oe] oe-stylize

[Frans Meulenbroeks]

Some questions wrt oe-stylize:

Do we still want to promote this?

If so, it seems useful to add the new keywords that have been
introduced last year or so.

Also a few issues:
oe-stylize moves the checksums immediately after the SRC_URI.
Is this desired? Most of the recipes have them near the end.

And I noticed that the script moves require lines.
I'm not too sure if that is ok. By moving them it is possible that
overriding variables (like depends) are moved from after the requires
to before the requires.
Is this a problem?

Best regards, Frans
