fixed since 1.7.002 not working update from 1.4:

- fs_link column is queried by sqlfs, but get created in 1.7.002
- pdo does not throw exception on sql errors, it silently ignores them
  --> told it now in constructor to also throw exceptions
- egw_vfs::find() was not always honoring the url option
