Speed up information schema privilege views

Instead of expensive cross joins to resolve the ACL, add table-returning function aclexplode() that expands the ACL into a useful form, and join against that. Also, implement the role_*_grants views as a thin layer over the respective *_privileges views instead of essentially repeating the same code twice. fixes bug #4596 by Joachim Wieland, with cleanup by me
