It is orthogonal to this change, but it would make sense for those
methods to be const as well.
Doing this requires interp::interp_ui_out to be const as well (as done
in attached patch).

I am wondering, is there a reason to make the solib parameter const for
solib_unloaded but not for solib_loaded?
Changing it to const seems to still compile just fine. If down the line
an observer needs to modify the SO, the observer's signature can be
adjusted.
