dlopen, dlsym, dlclose, dlerror

dlerror(3) is the same "returns a string and clears itself" trap as
strerror, which this library already has an answer for -- so the shape is
known and the work is applying it.

dlsym returning NULL legitimately (a symbol whose value is NULL) is the other
half: the documented way to tell that from failure is to clear dlerror first and
check it after, which is exactly the kind of ritual a wrapper should own.
