Expose conf_clear(), for test purposes.

Browse Source 
Normally you don't ever want to have a Conf structure that doesn't
have an entry for every primary key, because the code that uses Conf
to get real work done will fail assertions if lookups fail. But test
programs manipulating Conf in unusual ways are a special case.

(In particular, one thing you _can_ legally do with an empty Conf is
to call load_open_settings() to populate it. That has to be legal,
because it's how a Conf gets populated in the first place, after it's
initially created empty.)
