Get all of the parent classes of C{c}, not including C{c} itself, which are

The name comes from "all your base are belong to us", from the deprecated
L{twisted.python.reflect.allYourBase} function.

This type of object is persisted with versioning information.
I have a single class attribute, the int persistenceVersion. After I am
unserialized (and styles.doUpgrade() is called), self.upgradeToVersionX()
will be called for each version upgrade I must undergo.
For example, if I serialize an instance of a Foo(Versioned) at version 4
and then unserialize it when the code is at version 9, the calls::
self.upgradeToVersion5()
self.upgradeToVersion6()
self.upgradeToVersion7()
self.upgradeToVersion8()
self.upgradeToVersion9()
will be made. If any of these methods are undefined, a warning message
will be printed.
