Subject: sections/hints: prevent Not_found in get_type_of

due to cleared/reverted section variables.
This fixes the get_type_of but requires keeping information
around about the section hyps available in goals during resolution.
It's optimized for the non-section case (should incur no cost there),
and the case where no section variables are cleared.
