  sqlite3 module: Mark iterdump() method as "Non-standard" like all the other methods not found in DB-API.
........
  r66412 | gerhard.haering | 2008-09-12 13:58:57 -0500 (Fri, 12 Sep 2008) | 2 lines

  Fixes issue #3103. In the sqlite3 module, made one more function static. All renaming public symbos now have the pysqlite prefix to avoid name clashes. This at least once created problems where the same symbol name appeared somewhere in Apache and the sqlite3 module was used from mod_python.
