- partial revert of commit rev5359 for db_mysql module

- generalize db_str2val function in the DB API core, the string copying
  behaviour can now configured (its done for db_postgres, db_unixodbc,
  not done for db_mysql like in the 1.3, 1.4 branches)
- still TODO: fix NULL case in db_unixodbc, try to fix double copying
