Replaces calls directly to PermissionManager with calls to
the Authority object available from Context or the
GroupPermissionLookup service.
This patch does not address use of PermissionManager for
blocks.
Deprecations:
- ApiBase::checkUserRightsAny deprecated passing optional
User parameter
- ApiBase::checkTitleUserPermissions deprecated passing
LinkTarget as first parameter, takes PageIdentity instead
