Eek. This code is *inside* libsvn_client. Our typical pattern is that a
structure is opaque outside the library, but completely visible inside the
library. Thus, we don't need to use getters/setters within the library. The
code can simply refer to ctx-auth_baton.

 - SVN_ERR (repos_to_wc_copy (src_path, src_revision,
 - dst_path, optional_adm_access, auth_baton,
 - notify_func, notify_baton,

Why the whole error thing? Just return NULL. It could be quite a valid
approach for the caller to want to check if auth stuff has been installed or
not. They shouldn't have to deal with error returns.

Basically, it seems like there is too much engineering around what could
be a simple structure.
