Merge lp:~vila/bzr/514301-auth-config-unicode into lp:bzr

[Vincent Ladeuil]

AuthConfig alwaus return user/password as unicode.

This fixes bug #514301 by always returning unicode username/password when
typed by the user (using stdin encoding).

I cleaned up the tests where we enforced the wrong behaviour (let ui
returned encoded strings (including ascii) instead of unicode).

[Martin Packman (gz)]

Looks good.

We'll get the ui object doing the right thing with unicode, one method at a time...

review: Approve
