f2153f9716 Always allow OR connections to bridges on private addresses
Regardless of the setting of ExtendAllowPrivateAddresses.

This fixes a bug with pluggable transports that ignore the
(potentially private) address in their bridge line.

Fixes bug 18517; bugfix on 23b088907f in tor-0.2.8.1-alpha.

which supports extrainfo descriptors.

48f8229504 After we strip out duplicate entries from 'routers', don't use 'rl'.
We've got to make sure that every single subsequent calculation in
dirserv_generate_networkstatus_vote_obj() are based on the list of
routerinfo_t *after* we've removed possible duplicates, not before.
Fortunately, none of the functions that were taking a routerlist_t
as an argument were actually using any fields other than this list
of routers.

fa07c60c67 Fix another case of 17668: Add NoEdConsensus
I had a half-built mechanism to track, during the voting process,
whether the Ed25519 value (or lack thereof) reflected a true
consensus among the authorities.  But we never actually inserted this
field in the consensus.

The key idea here is that we first attempt to match up votes by pairs
of <Ed,RSA>, where <Ed> can be NULL if we're told that there is no
Ed key.  If this succeeds, then we can treat all those votes as 'a
consensus for Ed'.  And we can include all other votes with a
matching RSA key and no statement about Ed keys as being "also about
the same relay."

After that, we look for RSA keys we haven't actually found an entry
for yet, and see if there are enough votes for them, NOT considering
Ed keys.  If there are, we match them as before, but we treat them
as "not a consensus about ed".

When we include an entry in a consensus, if it does not reflect a
consensus about ed keys, then we include a new NoEdConsensus flag on
it.

This is all only for consensus method 22 or later.

Also see corresponding dir-spec patch.

13a31e72db Never vote for an ed key twice.
When generating a vote, and we have two routerinfos with the same ed
key, omit the one published earlier.

This was supposed to have been solved by key pinning, but when I
made key pinning optional, I didn't realize that this would jump up
and bite us.  It is part of bug 18318, and the root cause of 17668.

of calling router_get_my_routerinfo(), and now we no longer call that.)
