Clients avoid choosing nodes that can't do ntor
If we know a node's version, and it can't do ntor, consider it not running.
If we have a node's descriptor, and it doesn't have a valid ntor key,
consider it not running.

Refactor these checks so they're consistent between authorities and clients.

568dc27a19 Make base16_decodes return number of decoded bytes
base16_decodes() now returns the number of decoded bytes. It's interface
changes from returning a "int" to a "ssize_t". Every callsite now checks the
returned value.

4f1a04ff9c Replace nearly all XXX0vv comments with smarter ones
So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we
had better revisit this comment and fix it!"

But we have a huge pile of such comments accumulated for a large
number of released versions!  Not cool.

So, here's what I tried to do:

  * 0.2.9 and 0.2.8 are retained, since those are not yet released.

  * XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
    quite important!"

  * The others, after one-by-one examination, are downgraded to
    plain old XXX.  Which doesn't mean they aren't a problem -- just
    that they cannot possibly be a release-blocking problem.

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.

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.

8a4bba06d2 Rename crypto_digest_all, and digests_t.
They are no longer "all" digests, but only the "common" digests.

Part of 17795.

This is an automated patch I made with a couple of perl one-liners:

  perl -i -pe 's/crypto_digest_all/crypto_common_digests/g;' src/*/*.[ch]
  perl -i -pe 's/\bdigests_t\b/common_digests_t/g;' src/*/*.[ch]

Once tor is downloading a usable consensus, any other connection
attempts are not needed.

Choose a connection to keep, favouring:
* fallback directories over authorities,
* connections initiated earlier over later connections

Close all other connections downloading a consensus.
