gobject ship their parent class at position 0, then the subclass
attributes.
Thusly we have a "class overflow" when the parent class expand, it
would overwrite the sublcass fields in code that is build against the
old class API.
Here can_authenticate added to parent SoupAuth class would overflow its
subclass ESoupAuthBearer fields.

in commit https://git.gnome.org/browse/libsoup/commit/?id=6a8826f0d2545
9c943719b88f22619f22b81c547 , I only found an API change , SoupAuth .

SoupAuthNegotiate is only an addition.
