Subject: Remove factorial operators, leaving only the factorial() function.

The "!" operator is our only built-in postfix operator.  Remove it,
on the way to removal of grammar support for postfix operators.

There is also a "!!" prefix operator, but since it's been marked
deprecated for most of its existence, we might as well remove it too.

Also zap the SQL alias function numeric_fac(), which seems to have
equally little reason to live.
