bf3e32a452 Fix out-of-bounds write during voting with duplicate ed25519 keys
In dirserv_compute_performance_thresholds, we allocate arrays based
on the length of 'routers', a list of routerinfo_t, but loop over
the nodelist. The 'routers' list may be shorter when relays were
filtered by routers_make_ed_keys_unique, leading to an out-of-bounds
write on directory authorities.

This bug was originally introduced in 26e89742, but it doesn't look
possible to trigger until routers_make_ed_keys_unique was introduced
in 13a31e72.

Fixes bug 19032; bugfix on tor 0.2.8.2-alpha.

b24f15a9a1 In routers_make_ed_keys_unique, break ties for published_on
This ensures that if we can't use published_on to decide an ed,rsa
mapping, we at least decide deterministically.

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.

Resolves issue 18318.DG3.

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.

01733e2b15 New AuthDirPinKeys option to enable/disable keypinning enforcement
Implements ticket #17135.  We're going to need this one to avoid
chaos as everybody figures out how ed25519 keys work.

359faf5e4b New TestingDirAuthVote{Exit,Guard,HSDir}IsStrict flags
"option to prevent guard,exit,hsdir flag assignment"

"A node will never receive the corresponding flag unless
that node is specified in the
TestingDirAuthVote{Exit,Guard,HSDir} list, regardless of
its uptime, bandwidth, exit policy, or DirPort".

Patch modified by "teor": VoteOnHidServDirectoriesV2
is now obsolete, so TestingDirAuthVoteHSDir always
votes on HSDirs.

592a439107 Tie key-pinning logic into directory authority operation
With this patch:
  * Authorities load the key-pinning log at startup.
  * Authorities open a key-pinning log for writing at startup.
  * Authorities reject any router with an ed25519 key where they have
    previously seen that ed25519 key with a different RSA key, or vice
    versa.
  * Authorities warn about, but *do not* reject, RSA-only descriptors
    when the RSA key has previously gone along with an Ed25519 key.
    (We should make this a 'reject' too, but we can't do that until we're
    sure there's no legit reason to downgrade to 0.2.5.)

Fixes #15850, part of #15801. Change file is added by this commit. The
original comment in the reverted commit is removed because right now we
*need* a DirPort until #15849 is implemented so no doubt nor confusion there
anymore.
