Replace uses of PyCF_xxx with CO_xxx.

Replace individual feature slots in PyFutureFeatures with single
bitmask ff_features.

When flags must be transfered among the three parts of the interpreter
that care about them -- the pythonrun layer, the compiler, and the
future feature parser -- can simply or (|) the definitions.

Replace individual slots in PyFutureFeatures with a single bitmask
with one field per feature.  The flags for this bitmask are the same
as the flags used in the co_flags slot of a code object.

    XXX This means we waste several bits, because they are used
    for co_flags but have no meaning for future statements.  Don't
    think this is an issue.

Remove the NESTED_SCOPES_DEFAULT define and others.  Not sure what
they were for anyway.

Remove all the PyCF_xxx flags, but define PyCF_MASK in terms of the
CO_xxx flags that are relevant for this release.

Change definition of PyCompilerFlags so that cf_flags matches
co_flags.

  problem).  inherit_slots() is split in two parts: inherit_special()
  which inherits the flags and a few very special members from the
  dominant base; inherit_slots() which inherits only regular slots,
  and is now called for each base in the MRO in turn.  These are now
  both void functions since they don't have error returns.

- Added object.__setitem__() back -- for the same reason as
  object.__new__(): a subclass of object should be able to call
  object.__new__().

- add_wrappers() was moved around to be closer to where it is used (it
  was defined together with add_methods() etc., but has nothing to do
  with these).
