Pushed with some test cases; thanks for reviewing!

BTW, I noticed while making the test cases that there are some odd-seeming
behaviors as a result of early exits from the test functions.  For
instance,

regression=# create table mytab(f1 int, f2 int);
CREATE TABLE
regression=# select has_column_privilege('mytab',99::int2,'select');
 has_column_privilege 
----------------------
 t
(1 row)

One might reasonably expect NULL there, but column_privilege_check
observes that you have table-level select privilege so it doesn't
bother to look up the column number.  Not sure if this is worth
doing something about.
