* module.c (mio_component_ref): Return if the symbol is NULL
and wait for another iteration during module reads.
(mio_symtree_ref): Suppress the writing of contained symbols,
when a symbol is available in the main namespace.
(read_module): Restrict scope of special treatment of contained
symbols to variables only and suppress redundant call to
find_true_name.
