ff558f5aba Issue #29157: Prefer getrandom() over getentropy() 
* dev_urandom() now calls py_getentropy(). Prepare the fallback to support
  getentropy() failure and falls back on reading from /dev/urandom.
* Simplify dev_urandom(). pyurandom() is now responsible to call getentropy()
  or getrandom(). Enhance also dev_urandom() and pyurandom() documentation.
* getrandom() is now preferred over getentropy(). The glibc 2.24 now implements
  getentropy() on Linux using the getrandom() syscall.  But getentropy()
  doesn't support non-blocking mode. Since getrandom() is tried first, it's not
  more needed to explicitly exclude getentropy() on Solaris. Replace:
  "if defined(HAVE_GETENTROPY) && !defined(sun)"
  with "if defined(HAVE_GETENTROPY)"
* Enhance py_getrandom() documentation. py_getentropy() now supports ENOSYS,

19d246745d Issue #23722: improve __classcell__ compatibility 
Handling zero-argument super() in __init_subclass__ and
__set_name__ involved moving __class__ initialisation to
type.__new__. This requires cooperation from custom
metaclasses to ensure that the new __classcell__ entry
is passed along appropriately.

The initial implementation of that change resulted in abruptly
broken zero-argument super() support in metaclasses that didn't
adhere to the new requirements (such as Django's metaclass for
Model definitions).

The updated approach adopted here instead emits a deprecation
warning for those cases, and makes them work the same way they
did in Python 3.5.

This patch also improves the related class machinery documentation
to cover these details and to include more reader-friendly
cross-references and index entries.
