I have an important change to the auth-source API.  I am attaching a
patch against the Emacs trunk (including Tramp) to change calls of
`auth-source-user-or-password' to calls of `auth-source-search'.  The
code is not well tested yet and I will do a final test before pushing it
out in addition to revising the auth.texi manual and providing ChangeLog
entries.  I want to know if there are any comments or protests before
doing this.  Katsumi Yamaoka will have to synchronize his push from Gnus
with applying the patch, so I want this to be a smooth transition for
all the Emacs users and developers.  I plan to make it by Saturday
2011-02-10 so please let me know beforehand.

auth-source.el lives inside Gnus; the new version is in a branch there.
That branch also has *tested* fixes for all the Gnus calls of
auth-source-*.  That's why the attached Emacs patch doesn't include Gnus
changes.

I am attaching 1) auth-source.el from the Gnus tzz-auth-source-rewrite
branch; 2) the patch against the Emacs trunk including Tramp.

Thanks
Ted
