    HAWQ-1275. Check build-in catalogs, tables and functions in native aclcheck.

    We plan to do privilege check in hawq side for build-in catalogs, tables 
and functions. The reasons are two folds;
    1 Ranger mainly manage the user data, but build-in catalogs and tables are 
not related to user data(note that some of them contain statistics information 
of user data such as catalog table pg_aoseg_*).
    2 We haven't finish the code of merge of all the privilege check requests 
into one big request. Without it query such as "\d" and "analyze" will lead to 
hundreds of RPS request.
