Derek Hulley 6ce00a8372 ALF-7167: RINF 11: Canned queries
- ALF-9322: RINF 11: AbstractCannedQueryPermissions enhancements
   - Pulled in logic around hasMore() so that subclasses just have to obey
   - Added in cut-off size estimates
 - ALF-9337: RINF 11: Consolidate interceptor wrappers
   - Permissions respect PermissionCheckedValue
   - Added last-in-chain "afterAclMarking" to "afterInvocationManager": marks collections as checked
   - Added 'mixin' interfaces to handle input and output for permission checking of collections
