 AuthDirPublishIPv6 is AUTOBOOL.
 AUTOBOOL defaults to -1.
 We check AuthDirPublishIPv6 like this

 {{{
     options->AuthDirHasIPv6Connectivity == 0
 }}}

 in two places where we want to test whether it's "unset" or not. This
 test will fail for AuthDirPublishIPv6 being -1.

 After an interesting discussion with Roger on IRC, I suggest we make
 this option BOOL.

 The motivation is that we should have AUTOBOOL options only for things
 decided from information from the consensus or the operating system
 we're running on. Once we have code for autodetecting IPv6 support
 from the OS we can turn it back into an AUTOBOOL again.
