I spoke with the directory authority operators about this, and they are happy with the existing behaviour. But we need to document it:

• if no voting authorities set AuthDirHasIPv6Connectivity, there will be no IPv6 addresses in the consensus
• if a minority of voting authorities set AuthDirHasIPv6Connectivity, relays with unreachable IPv6 addresses will have those addresses removed from the consensus
• if a majority of voting authorities set AuthDirHasIPv6Connectivity, relays with unreachable IPv6 addresses will not be listed as running

Trac:
Description: Otherwise, we lose useful relays when authorities set AuthDirHasIPv6Connectivity.

This code looks good to me, modulo open questions on proposal 283 [*]. After we discuss them, we should either merge this, or put it into needs_revision, depending on the outcome.
