Persist a user id and a backend in the request. This way a user doesn't
have to reauthenticate on every request. Note that data set during
the anonymous session is retained when the user logs in.

Take the current request and the updated user object from which the new
session hash will be derived and update the session hash appropriately to
prevent a password change from logging out the session from which the
password was changed.
