py-ZopeComponent: updated to 5.0.0

5.0.0 (2021-03-19)
==================

- Remove backwards compatibility imports that were emitting
  deprecation warnings. This affects certain imports from
  ``zope.component.interfaces`` (which should be imported from
  ``zope.interface.interfaces``) as well as certain imports from
  ``zope.component.registery`` (import from
  ``zope.interface.registry``), and the entire
  ``zope.component.hookable`` module.

- Respect permission value for utility factory registrations

- Add support for Python 3.9

- Fix the ``<subscriber>`` ZCML directive to allow a missing
  ``provides=`` attribute when a ``factory=`` is given and the Python
  object has been decorated with ``@implementer`` and implements a
  single interface. This has been documented, but hasn't worked
  before.

- Make ``PersistentAdapterRegistry`` use persistent objects
  (``PersistentMapping`` and ``PersistentList``) for its internal data
  structures instead of plain dicts and lists. This helps make it
  scalable to larger registry sizes.

  This requires zope.interface 5.3.0a1 or later.

  New registries (and their primary users, ``PersistentComponents`` and
  zope.site's ``LocalSiteManager``) take full advantage of this
  automatically. For existing persistent registries to take advantage
  of this, you must call their ``rebuild()`` method and commit the
  transaction.

- Fix ``zope.interface.interface.provideInterface`` and the various
  search and query methods to use the current site manager instead of
  always using the global site manager. (``provideInterface`` is
  called implicitly when registering components from ZCML.) The search
  and query methods continue to return interfaces registered in base
  site managers.
