Include GUC's unit, if it has one, in out-of-range error messages.
This should reduce confusion in cases where we've applied a units
conversion, so that the number being reported (and the quoted range
limits) are in some other units than what the user gave in the
setting we're rejecting.
Some of the changes here assume that float GUCs can have units,
which isn't true just yet, but will be shortly.
