Changes a isc_throw output too.

Reviewed via jabber.

In cases where we use values outside of normal character range (-128
to 127 or 0 to 255) to indicate special things, like EOF, we need to
insure that we can hold these values. To do that, we use an int.

It turns out that the default type conversions also meant that our
JSON conversion from strings would break in some cases. A test was
added to show that, and to confirm the fix.
