Bug 29336: Identify the fields with wrong length (or name) first

This report will fix the bad lengths first.

Bad name means: refers to value, should be category.
Scanning kohastructure.sql.

Note: Bug 29347 has been opened to fix the names.

Test plan:
Search for another AV category field with length<>32.
Bonus: Reinstall and check database.
