revset: fix order of nested '_(|int|hex)list' expression (BC) This fixes the order of 'x & (y + z)' where 'y' and 'z' are trivial, and the other uses of _list()-family functions. The original functions are renamed to '_ordered(|int|hex)list' to say clearly that they do not follow the subset ordering.
