Make database plugin responsible for releasing the error-message string, so

that we can use the krb5_get_error_message interface internally.

* kdb5.h: Add release_errcode_string field to the interface.
* db2_exp.c, ldap_exp.c: Initialize it.
* ldap_misc.c: Use krb5_get/free_error_message for error message strings.
* kdb_ldap.h: Declare krb5_ldap_release_errcode_string.
