Get rid of __defined__ and tp_defined -- there's no need to

tp_cache takes its place -- but this hasn't been implemented yet.

Type/class unification and new-style classes
! - New-style classes are now dynamic by default. Previous, they were
! static (meaning class attributes could not be assigned to) and
! dynamic classes had to be requested by adding __dynamic__ = 1 to the
! body of the class or to the module. Static classes are faster than
! dynamic classes, but dynamic classes are now at most 50% slower than
! static classes; previously, they could be up to 10x slower. (This
! was accomplished by making dynamic classes faster, not by making
! static classes slower. :-) Note that according to one benchmark,
! static classes are about the same speed as classic classes.
- C.__doc__ now works as expected for new-style classes (in 2.2a4 it

Type/class unification and new-style classes
! - New-style classes are now always dynamic (except for built-in and
! extension types). There was no longer a performance penalty, and I
! no longer see another reason to keep this baggage around. One relic
! remains: the __dict__ or a new-style class is a read-only proxy.
! You must set the class's attribute to modify. As a consequence, the
! __defined__ attribute of new-style types no longer exists, for lack
! of need: there is once again only one __dict__ (although in the
! future a __cache__ may be resurrected in its place).
