d5a95e1ea1 Do not truncate too long hostnames
If a hostname is supplied to tor-resolve which is too long, it will be
silently truncated, resulting in a different hostname lookup:

$ tor-resolve $(python -c 'print("google.com" + "m" * 256)')

If tor-resolve uses SOCKS5, the length is stored in an unsigned char,
which overflows in this case and leads to the hostname "google.com".
As this one is a valid hostname, it returns an address instead of giving
an error due to the invalid supplied hostname.

ae89d9745d Revert ticket 20982 changes.
They broke stem, and breaking application compatibility is usually a
bad idea.

This reverts commit 6e10130e18,
commit 78a13df158, and
commit 62f52a888a.

We might re-apply this later, if all the downstream tools can handle
it, and it turns out to be useful for some reason.

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?

Fixes bug 20553; bugfix on 0.0.2pre8

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.

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.

ce854a8d22 Add -ftrapv to gcc-hardening ... mostly!
We know there are overflows in curve25519-donna-c32, so we'll have
to have that one be fwrapv.

Only apply the asan, ubsan, and trapv options to the code that does
not need to run in constant time.  Those options introduce branches
to the code they instrument.

(These introduced branches should never actually be taken, so it
might _still_ be constant time after all, but branch predictors are
complicated enough that I'm not really confident here. Let's aim for
safety.)

Closes 17983.

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.

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!

d2cb923320 Remove tor-fw-helper code
It did a good idea, but the code-quality of libupnpc and libnatpnp

Tor proper.  Instead, we'll recommend that people do the pure-go
reimplementation instead.  Closes ticket 13338.

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.
