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.

Closes ticket 17796.

263f6d11fd Mark all object files built based on micro-revision.i as depending on it 
Fixes make -j for some users; fixes bug 17826.

Bugfix on 0.2.5.1, when we started building testing versions of all
the object files.

6365859825 Disable the dynlock functions we were giving openssl. 
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.

2b9b694410 Remove config.log from CLEANFILES 
Fixes bug 17924; bugfix on 0.2.4.1-alpha.

In ddf5020ea8, we added config.log to CLEANFILES in doc/Makefile.am
so that distcheck would be happy about the presence of doc/config.log.
But when we moved to nonrecursie makefiles in 2a4a149624, we
accidentally left that filename unchanged, so that it referred to
config.log instead.

Patch from cypherpunks.

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.

Convention is that router_dump_router_to_string() should look at its
input "router", which should be generated by

997f779a7f Add new DirCache configuration option 
This will give relay operators the ability of disabling the caching of

lower-resource systems it may beneficial.
