Makes the code more efficient, and much more readable.

Exploring Zope code finally revealed what we needed in the
code, to allow removing the "trick".
It's a "trick" because we have no real reason to call
again the __init__ method of a metaclass: it's nicer to
understand what we need to do and to do it explicitely.

In this case, the __get__ slot was missing after the __bases__
assignement (bases are recomputed and as a result __get__ is
null'ed), and there is a method exposed in Zope's ExtensionClass
to do exactly this and only this.

The InitializeClass calls are included because
ExtensionClass.__init__ calls __class_init__, which sets correctly
roles and security on the class.

1) Do not use gc.get_referrers as this is highly inefficient.
(the returned list contains a lot of objects, some of them
are persistent objects, some of them are not classes, etc, etc...
But worse, "dead" objects with a zero reference count can be returned
by this function, and this function would "ressucitate" them.
gc.get_referrers for application code is usually a bad idea)

2) Use instead a Python metaclass to track who's been subclassing
a portal type class, and after a change on the portal type class,
we just call the efficient PortalTypeMetaClass.getSubclassList to
get descendants.

it is evil to recreate the attributes during _aq_reset.

Scenario:
 * First call to aq_dynamic
 * aq_portal_type = Base.aq_portal_type
    - inner aq_dynamic business
    - causing an aq_reset call
    - Base.aq_portal_type = {}
    - [...]
    - return
* local aq_portal_type is not anymore Base.aq_portal_type

The symptoms are random, hard to reproduce loud KeyError crashes in
  hasattr(aq_portal_type[aq_key], accessor_name, None)
that disappear on the second try.
