[gnugo-devel] fixed anchor

[Arend Bayer]

- maintenance to allow owl_attackpats.db to be built with fixed anchor

This just adds anchor elements ('Y') to the patterns in owl_attackpats.db
where they were missing; adds missing "callback_data" to the file; and
patches mkpat.c to enforce an explicit anchor when compiling with
-a.

(I didnt actually test whether that would be beneficial. If someone
wants to try this, he will have to regenerate the owl_attackpat.dtr file
first.)
