83129031b1 Remove a needless level of indirection from crypto_cipher_t
Now that crypto_cipher_t only contains a pointer, it no longer
has any reason for an independent existence.

5e30e26c6d Chop another ~93 RSA key generations out of the unit tests
We have a mock for our RSA key generation function, so we now wire
it to pk_generate(). This covers all the cases that were not using
pk_generate() before -- all ~93 of them.

94bff894f9 Fix a large pile of solaris warnings for bug 19767.
In nearly all cases, this is a matter of making sure that we include
orconfig.h before we include any standard c headers.

53a3b39da1 Add -Wmissing-variable-declarations, with attendant fixes
This is a big-ish patch, but it's very straightforward.  Under this
clang warning, we're not actually allowed to have a global variable
without a previous extern declaration for it.  The cases where we
violated this rule fall into three roughly equal groups:
  * Stuff that should have been static.
  * Stuff that was global but where the extern was local to some
    other C file.
  * Stuff that was only global when built for the unit tests, that
    needed a conditional extern in the headers.

The first two were IMO genuine problems; the last is a wart of how
we build tests.

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]

39b597c2fd Restrict the meaning of digests_t to sha1+sha256.
This saves CPU and RAM when handling consensuses and x509 certs.

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.

dedea28c2e Make crypto_seed_rng() and crypto_rand() less scary.
These functions must really never fail; so have crypto_rand() assert
that it's working okay, and have crypto_seed_rng() demand that
callers check its return value.  Also have crypto_seed_rng() check
RAND_status() before returning.

347fe449fe Move formatting functions around.
The base64 and base32 functions used to be in crypto.c;
crypto_format.h had no header; some general-purpose functions were in
crypto_curve25519.c.

This patch makes a {crypto,util}_format.[ch], and puts more functions
there.  Small modules are beautiful!

efa21bb941 Implement proposal 228: cross-certification with onion keys
Routers now use TAP and ntor onion keys to sign their identity keys,
and put these signatures in their descriptors.  That allows other
parties to be confident that the onion keys are indeed controlled by
the router that generated the descriptor.

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.

3f41318472 Add crypto_rand_int_range() and use it
Incidently, this fixes a bug where the maximum value was never used when
only using crypto_rand_int(). For instance this example below in
rendservice.c never gets to INTRO_POINT_LIFETIME_MAX_SECONDS.

  int intro_point_lifetime_seconds =
    INTRO_POINT_LIFETIME_MIN_SECONDS +
    crypto_rand_int(INTRO_POINT_LIFETIME_MAX_SECONDS -
                    INTRO_POINT_LIFETIME_MIN_SECONDS);
