Cindy Cicalese f6e1891c6f Use Authority and GroupPermissionLookup in Action API
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
