Following the discussion on this thread I'm trying to get rid of
QtWebEngine's dependency on qtbase and qtdeclarative private
headers/symbols, and I'm hitting one case where we might not necessarily
want the API to be public [1]. Intermodule API doesn't have to be as
robust as public API and it would be nice to keep it that way.

Concretely, what would be the best way to define and maintain such an
intermodule API?

In the change I'm simply marking public functions as \internal for the
documentation, but this might not be enough to discourage applications
from using it.

Another option I see is to name them _q_something as we already do for
other publically exported private functions. Or maybe somebody has other
ideas, what do you think?
