The generator translates Bool/OBool to int for external
APIs (because it has to for backwards compatibility with
very old versions that predate our use of stdbool.h).  However
it could probably use bool internally (eg. for the daemon)
but doesn't at the moment.

However inspect_do_decrypt is an internal API between
parts of the tools, and also isn't generated, so we can
do whatever we want for this one.
