common: Add missing error code GPG_ERR_WRONG_NAME.

* configure.ac: Require libgpg-error 1.25.
* common/util.h: Define some extra error codes.

This actually defines a few more error ocdes in case they are used by
backported code. The requirement chnaged to 1.25 because erro codes
from there are also required.
