83513a93a1 Check tor_sscanf return value in test_crypto.c 
Coverity noticed that we check tor_sscanf's return value everywhere
else.

ed0ecd9f13 Use tor_sscanf, not sscanf, in test_crypto.c 
Fixes the 0.2.9 instance of bug #19213, which prevented mingw64 from
working.  This case wasn't in any released Tor.

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]

27582325dc Make Tor build happily with OpenSSL master and libressl. 
Also tested with 1.0.0t and 1.0.2f.

Closes ticket 19784.

Closes most of 17921. (Still need to make some tests pass.)

081b159abc Add the randomized large buffer test for SHA-3 incremental hashing. 
This creates a random 100 KiB buffer, and incrementally hashes
(SHA3-512) between 1 and 5 * Rate bytes in a loop, comparing the running
digest with the equivalent one shot call from the start of the buffer.

9467485517 Add crypto_xof_t and assorted routines, backed by SHAKE256. 
This is an eXtendable-Output Function with the following claimed
security strengths against *all* adversaries:

 Collision: min(d/2, 256)
 Preimage: >= min(d, 256)
 2nd Preimage: min(d, 256)

 where d is the amount of output used, in bits.

687f9b3bd7 Add the SHA-3 hash functions to common/crypto.h. 
* DIGEST_SHA3_[256,512] added as supported algorithms, which do
   exactly what is said on the tin.
 * test/bench now benchmarks all of the supported digest algorithms,
   so it's possible to see just how slow SHA-3 is, though the message
   sizes could probably use tweaking since this is very dependent on
   the message size vs the SHA-3 rate.

or incrementing values (OpenSSL's rand_predictable feature).

840e68d917 Integrate and enable ed25519-donna. 
The runtime sanity checking is slightly different from the optimized
basepoint stuff in that it uses a given implementation's self tests if
available, and checks if signing/verification works with a test vector
from the IETF EdDSA draft.

The unit tests include a new testcase that will fuzz donna against ref0,
including the blinding and curve25519 key conversion routines.  If this
is something that should be done at runtime (No?), the code can be
stolen from there.

Note: Integrating batch verification is not done yet.

f079c27761 Integrate the accelerated Curve25519 scalar basemult. 
Integration work scavanged from nickm's `ticket8897_9663_v2` branch,
with minor modifications.  Tor will still sanity check the output but
now also attempts to catch extreme breakage by spot checking the
optimized implementation vs known values from the NaCl documentation.

Implements feature 9663.

and check those signatures as documented in proposal 220.

f8f407d66a Now that OpenSSL 0.9.8 is dead, crypto_seed_rng() needs no args 
It needed an argument before because it wasn't safe to call
RAND_poll() on openssl 0.9.8c if you had already opened more fds
than would fit in fd_set.

915c7438a7 Add "ADD_ONION"/"DEL_ONION" and "GETINFO onions/*" to the controller. 
These commands allow for the creation and management of ephemeral
Onion ("Hidden") services that are either bound to the lifetime of
the originating control connection, or optionally the lifetime of
the tor instance.

Implements #6411.
