I've now made these changes, but haven't pushed them yet.  I'm now able
to visit that Mexican museum site with eww.  :-)

The changes are basically

        (make-network-process :name name :buffer buffer
-                             :host host :service service
+                             :host (puny-encode-domain host) :service service

in the calls to `make-network-process' in network-stream.el.
`puny-encode-domain' is a NOP for all normal, non-IDNA domain names, so
the potential for breakage should be pretty small...

Does anybody object to this change, or have a suggestion as to how to do
this in a different way?
