Comment (by cypherpunks):

 My motivation of this patch (respect RFC6890) is to deal with local
 firewall warnings,
 and yes it will not fix the problem when different tor versions have
 different knowledge about special-purpose address blocks.

 Respect RFC6890 and disallow special-purpose address blocks.

 Data from section
 2.2.2.  IPv4 Special-Purpose Address Registry Entries
 where attribute "Global" set to False

 FIXME: for Global N/A definition, needs more clarification

 Also disallow multicast destinations because tor don't use multicast.
