WsgiDAV 3.0.0a6

on Python PyPI

Refactor domain_controller and authentication:

• Renamed environ["http_authenticator.realm"], environ["http_authenticator.user_name"]
  => environ["wsgidav.auth.realm"], environ["wsgidav.auth.user_name"]
• DC may define environ["wsgidav.auth.roles"] and environ["wsgidav.auth.permissions"]
• A common base class simplifies implementation of custom DCs.
• New PAMDomainController
  allows to authenticate system users on Linux and macOS, for example.
• Digest hash generation is now delegated to DomainControllers. This allows
  to implement DomainControllers that support digest access authentication
  even if plain-text passwords are not accessible, but stored hashes are.
• Every domain controller now has a config section of its own. E.g.
  the user_mapping option for SimpleDomainController was moved to
  simple_dc.user_mapping.
• SimpleDomainController no longer allows anonymous access by default.
  It is now required to pass simple_dc.user_mapping: "share1": True.
  Also a new pseudo-share "*" can be used to define defaults.
