Repurpose scm_i_port_weak_hash to associate an alist with each port.
* libguile/ports.c (scm_i_port_weak_hash): Document that the values in
this hash table will now be alists. Previously the value slots were
unused.
(scm_new_port_table_entry): Change the initial value of the entry in
scm_i_port_weak_hash from SCM_BOOL_F to SCM_EOL.
