c213f277cd Make bridge clients prefer the configured bridge address 
When ClientPreferIPv6ORPort is auto, bridges prefer the configured
bridge ORPort address. Otherwise, they use the value of the option.
Other clients prefer IPv4 ORPorts if ClientPreferIPv6ORPort is auto.

When ClientPreferIPv6DirPort is auto, all clients prefer IPv4 DirPorts.

c625ab9f5a Validate the DH parameters for correctness. 
We use sensible parameters taken from common sources, and no longer
have dynamic DH groups as an option, but it feels prudent to have
OpenSSL validate p and g at initialization time.

5f7df92571 Remove support for unsigned time_t 
We've never actually tested this support, and we should probably assume
it's broken.

To the best of my knowledge, only OpenVMS has this, and even on
OpenVMS it's a compile-time option to disable it.  And I don't think
we build on openvms anyway.  (Everybody else seems to be working
around the 2038 problem by using a 64-bit time_t, which won't expire
for roughly 292 billion years.)

Closes ticket 18184.

be841f77aa Compatibility defines should be used for LibreSSL. 
LibreSSL doesn't use OpenSSL_version (it uses the older SSLeay_version
API), but it reports a major version number as 2 in
OPENSSL_VERSION_NUMBER. Instead of fudging the version check, for now,
let's just check if we're using LibreSSL by checking the version number
macro exists, and use compatibility defines unconditionally when we
detect LibreSSL.

110765f556 Use get_interface6_via_udp_socket_hack() properly in _list(). 
When _list() is called with AF_UNSPEC family and fails to enumerate
network interfaces using platform specific API, have it call
_hack() twice to find out IPv4 and/or IPv6 address of a machine Tor
instance is running on. This is correct way to handle this case
because _hack() can only be called with AF_INET and AF_INET6 and
does not support any other address family.

488cdee5e7 When allocating a crypto_digest_t, allocate no more bytes than needed 
Previously we would allocate as many bytes as we'd need for a
keccak--even when we were only calculating SHA1.

OpenSSL doesn't use them, and fwict they were never called. If some
version of openssl *does* start using them, we should test them before
we turn them back on.

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.

5356eba6ca Use tor specific headers and memwipe() instead of memset_s(), and build. 
This is where things get tor specific.  It's just replacing stdint.h
and memset_s with the tor compat code so going back is trivial...

18685df031 Expose an incremental API in addition to the one-shot routines. 
The digest routines use init/update/sum, where sum will automatically
copy the internal state to support calculating running digests.

The XOF routines use init/absorb/squeeze, which behave exactly as stated
on the tin.
