[PATCH] Caseless UUID comparsion in search command

[Daniel Mierswa]

Just like some time ago in search_fs_uuid() the search_fs() function of
search also needs to be caseless when comparing UUIDs, for some reason
GRUB2 didn't find my UUID although I entered it as reported by blkid. To
be on the safe side, just use strncasecmp. :) Patch against git master
and ChangeLog attached. I await your feedback. :-)

If you still don't like it, that's ok: that's why I'm boss. I simply
know better than you do.

        * commands/search.c (search_fs): use `strcasecmp' for UUID comparsion.
