Description

The database backend has code to drop entries by tag wildcards (tag_foo_*).

- This fires a slow LIKE query
- No other backend supports this way of tag dropping, and no other backend will ever do so.

So this implementation violates the common backend API and must be removed. Fortunatly I've never seen any usage of this 'feature' in the wild and I'm pretty sure we can safely remove it.
