phabricator: split auth.url into the standard auth.schemes and auth.prefix
It seems better to reuse the existing function to find the proper [auth] block,
even if not all of the possible settings may be of interest.
The other callers of readauthforuri() make a trip through the password database
to fetch the user from the URI. But in the little experimenting I did here, the
username always came back as None. Since readauthforuri() wants it to make sure
that user@prefix matches user@url, it seems that parsing the URL and pulling out
the user component should be equivalent.
