listener: restore and improve method completion.

The recent autoload changes have degraded method completion,
which didn't work well in the first place.

Test case: with this change you can type term.(go[Tab] to
complete to term.(go-raw  or term.(go-cbreak.

* parser.c (find_matching_syms): Do not use the get_slot_syms
function for finding method and slot symbols. Just use
get_visible_syms, like for other bindings. Instead, in the switch
statement in the loop, for the 'M' (method) and 'S' (slot)
completion types, we use the static_slot_types and slot_types
functions to inquire whether a symbol has a binding. And these
two functions do something important: unlike get_slot_syms,
they trigger autoload.

* struct.c (get_slot_syms): Function removed.

* struct.h (get_slot_syms): Declaration removed.
