Nick Mathewson 9b18b215bb Work around a behavior change in openssl's BUF_MEM code
In our code to write public keys to a string, for some unfathomable
reason since 253f0f160e, we would allocate a memory BIO, then
set the NOCLOSE flag on it, extract its memory buffer, and free it.
Then a little while later we'd free the memory buffer with
BUF_MEM_free().

As of openssl 1.1 this doesn't work any more, since there is now a
BIO_BUF_MEM structure that wraps the BUF_MEM structure.  This
BIO_BUF_MEM doesn't get freed in our code.

So, we had a memory leak!

Is this an openssl bug?  Maybe.  But our code was already pretty
silly.  Why mess around with the NOCLOSE flag here when we can just
keep the BIO object around until we don't need the buffer any more?

Yawning Angel 0116eae59a Bug19499: Fix GCC warnings when building against bleeding edge OpenSSL.
The previous version of the new accessors didn't specify const but it
was changed in master.

Yawning Angel b563a3a09d Bug 19406: OpenSSL made RSA and DH opaque in 1.1.0.
There's accessors to get at things, but it ends up being rather
cumbersome.  The only place where behavior should change is that the
code will fail instead of attempting to generate a new DH key if our
internal sanity check fails.

Like the previous commit, this probably breaks snapshots prior to pre5.

Yawning Angel 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.

Nick Mathewson 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!

Nick Mathewson d2cb923320 Remove tor-fw-helper code
It did a good idea, but the code-quality of libupnpc and libnatpnp
is so dodgy that I'm not really comfortable including them alongside
Tor proper.  Instead, we'll recommend that people do the pure-go
reimplementation instead.  Closes ticket 13338.

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.

Fixes bug 13295; bugfix on 0.2.5.3-alpha.

can.

(And replay them once we know our first real logs.)

This is an implementation for issue 6938.  It solves the problem of
early log mesages not getting sent to log files, but not the issue of
early log messages not getting sent to controllers.

Nick Mathewson a3e0a87d95 Completely refactor how FILENAME_PRIVATE works
We previously used FILENAME_PRIVATE identifiers mostly for
identifiers exposed only to the unit tests... but also for
identifiers exposed to the benchmarker, and sometimes for
identifiers exposed to a similar module, and occasionally for no
really good reason at all.

Now, we use FILENAME_PRIVATE identifiers for identifiers shared by
Tor and the unit tests.  They should be defined static when we
aren't building the unit test, and globally visible otherwise. (The
STATIC macro will keep us honest here.)

For identifiers used only by the unit tests and never by Tor at all,
on the other hand, we wrap them in #ifdef TOR_UNIT_TESTS.

This is not the motivating use case for the split test/non-test
build system; it's just a test example to see how it works, and to
take a chance to clean up the code a little.

Apparently some compilers like to eliminate memset() operations on

possible replacement, which might be a bit slow.  I don't think this
is critical path in any way that will affect performance, but if it
is, we can work on that in 0.2.4.
