conf: Demote overlapping port ranges error to a warning

We give a fatal error if the port ranges from any port forwarding
specifiers overlap.  This occurs even if those port ranges are specifically
bound to different addresses, so there's not really any overlap.

Right now, we can't 100% handle this case correctly, because our data
structures don't have a way to represent per-address forwarding.  However,
there are a number of cases that will actually work just fine: e.g. mapping
the same port to the same port on two different addresses (say :: and
127.0.0.1).

We have long term plans to fix this properly, but that is still some time
away.  For the time being, demote this error to a warning so that the cases
that already work will be allowed.
