Binding perl: many improvements

 * lang.py: use lasso_unref instead of g_object_unref.
 * lang.py: handle 'optional' annotation for more types, needed by
   ID-WSF bindings.
 * lang.py, gobject_handling.c: check object type before making the C
   call
 * Makefile.am: improve silent rules, hide all normal output, show
   errors, and with V=1 shows everything
 * glist_handling.c, gobject_handling.c: make local functions static
 * t/Lasso.t: add non regression test for method receiver type checking.
 * glist_handlind.c; remove unused convertion functions.
 * lang.py: clear the semi-assigned list and croak if all list elements
   do not convert to non-NULL values.
