46cf63bb42 Fill in the list of blacklisted signing keys.
I used a list of certificate files from arma, and a little script,
both at 11464.

bd3db82906 New sort order for server choice of ciphersuites.
Back in 175b2678, we allowed servers to recognize clients who are
telling them the truth about their ciphersuites, and select the best
cipher from on that list. This implemented the server side of proposal
198.

In bugs 11492, 11498, and 11499, cypherpunks found a bunch of mistakes
and omissions and typos in the UNRESTRICTED_SERVER_CIPHER_LIST we had.
In #11513, I found a couple more.

Rather than try to hand-edit this list, I wrote a short python script
to generate our ciphersuite preferences from the openssl headers.

The new rules are:
  * Require forward secrecy.
  * Require RSA (since our servers only configure RSA keys)
  * Require AES or 3DES. (This means, reject RC4, DES, SEED, CAMELLIA,
    and NULL.)
  * No export ciphersuites.

Then:
  * Prefer AES to 3DES.
  * If both suites have the same cipher, prefer ECDHE to DHE.
  * If both suites have the same DHE group type, prefer GCM to CBC.
  * If both suites have the same cipher mode, prefer SHA384 to SHA256
    to SHA1.
  * If both suites have the same digest, prefer AES256 to AES128.

4231729176 Update ciphers.inc to match ff28
The major changes are to re-order some ciphers, to drop the ECDH suites
(note: *not* ECDHE: ECDHE is still there), to kill off some made-up
stuff (like the SSL_RSA_FIPS_WITH_3DES_EDE_CBC_SHA suite), to drop
some of the DSS suites... *and* to enable the ECDHE+GCM ciphersuites.

This change is autogenerated by get_mozilla_ciphers.py from
Firefox 28 and OpenSSL 1.0.1g.

Resolves ticket 11438.

a68e6ea9c0 Fix documentation of torrc search order
We are searching @CONFDIR@ before $HOME, but the documentation
implied otherwise.

I screwed this up in f5e86bcd6c, when I
first documented the $HOME/.torrc possibility.

wiki.

2658e70d16 Fix geoip by falling back to registered countries.
See 1d2179bc90 in master for details.

"""
Fall back to registered country if necessary.

When extracting geoip and geoip6 files from MaxMind's GeoLite2 Country
database, we only look at country->iso_code which is the two-character ISO
3166-1 country code of the country where MaxMind believes the end user is
located.

But if MaxMind thinks a range belongs to anonymous proxies, they don't put
anything there.  Hence, we omit those ranges and resolve them all to '??'.
That's not what we want.

What we should do is first try country->iso_code, and if there's no such
key, try registered_country->iso_code which is the country in which the
ISP has registered the IP address.

In short: let's fill all A1 entries with what ARIN et. al think.

does not do this, so let's just look for a2x.py as well.

3f567f529f gcc/clang: Mark macro-generated functions as possible unused
clang 3.4 introduced a new by-default warning about unused static
functions, which we triggered heavily for the hashtable and map function
generating macros. We can use __attribute__ ((unused)) (thanks nickm for
the suggestion :-) ) to silence these warnings.

9bb34aa897 Survive fedora's openssl in our benchmarks
Apparently fedora currently has ECDH but not P224. This isn't a huge
deal, since we no longer use OpenSSL's P224 ever (see #9780 and
72c1e5acfe). But we shouldn't have segfaulting benchmarks really.

1068e50aec Discard circuit paths on which nobody supports ntor
Right now this accounts for about 1% of circuits over all, but if you
pick a guard that's running 0.2.3, it will be about 6% of the circuits
running through that guard.

Making sure that every circuit has at least one ntor link means that
we're getting plausibly good forward secrecy on every circuit.

This implements ticket 9777,
