#2101: SQL hooks for calling selectivity functions

Comment(by pramsey):

 Oh, and for those wondering (like me) how to create a 'regclass' so you
 can call this function, regclass just takes in table names as strings,
 schema qualified or not, and happily spits out the right object, so
 select _postgis_geometry_sel('mytable','mycol','LINESTRING(0 0, 30 30)');
 will work thanks to the magic of auto-casting.
