I could change it to `const std::vector<solib *> &` or
`gdb::array_view<solib *>`.  The latter sounds better, since callers
don't need to know they are stored in a vector (we could also return an
even more generic "range" type, but I guess that would require more
boilerplate (unless we already have a class to accomplish this easily
that I forgot about?).

Like a "first_solib ()" method?  I certainly can do that.
