Set bindir, datadir & others if --basedir is given. This ensures that one only has to set basedir in [mysqld] group when moving a binary installation to a not default polace
Use for now safe_mysqld by default. (unless use-manager is set in the [mysql.server] option in my.cnf)
Search first for defaults files in basedir and then in datadir (like mysqld_safe)

  I removed the test for localstatedir as default.c doesn't anymore read defaults files from localstatedir
