config/output: Use INT_MAX as x/y unset value

We oftne use -1 to indicate unset values. In case of output (x, y), we
would consider the fields set if they are not both -1. This means that
(0, -1) and (-1, 0) are valid coordinates, but (-1, -1) is not.

We support negative output positioning, so we cannot use -1 to mean
unset. Zero is also not an option as that would disallow reverting a set
position back to (0, 0).

INT_MAX is an unreasonable output position, so use it to indicate unset
values, and only use the value when both are set.
