MD5/SHA1 and MDC-2 have special-case logic beyond the generic DigestInfo
wrapping. Test that each of these works, including hash and length
mismatches (both input and signature). Also add VerifyRecover tests. It
appears 5824cc2981 added support for
VerifyRecover, but forgot to add the test data.

RFC 3447, section 8.2.2, steps 3 and 4 states that verifiers must encode
the DigestInfo struct and then compare the result against the public key
operation result. This implies that one and only one encoding is legal.
OpenSSL instead parses with crypto/asn1, then checks that the encoding
round-trips, and allows some variations for the parameter. Sufficient
laxness in this area can allow signature forgeries, as described in
https://www.imperialviolet.org/2014/09/26/pkcs1.html
Although there aren't known attacks against OpenSSL's current scheme,
this change makes OpenSSL implement the algorithm as specified. This
avoids the uncertainty and, more importantly, helps grow a healthy
ecosystem. Laxness beyond the spec, particularly in implementations
which enjoy wide use, risks harm to the ecosystem for all. A signature
producer which only tests against OpenSSL may not notice bugs and
accidentally become widely deployed. Thus implementations have a
responsibility to honor the specification as tightly as is practical.
In some cases, the damage is permanent and the spec deviation and
security risk becomes a tax all implementors must forever pay, but not
here. Both BoringSSL and Go successfully implemented and deployed
RSASSA-PKCS1-v1_5 as specified since their respective beginnings, so
this change should be compatible enough to pin down in future OpenSSL
releases.

As a bonus, by not having to deal with sign/verify differences, this
version is also somewhat clearer. It also more consistently enforces
digest lengths in the verify_recover codepath. The NID_md5_sha1 codepath
wasn't quite doing this right.

1) Remove some unnecessary fixtures
2) Add EXECUTE_TEST_NO_TEARDOWN shorthand when a fixture exists but has
no teardown.
3) Fix return values in ct_test.c (introduced by an earlier refactoring,
oops)
Note that for parameterized tests, the index (test vector) usually holds all the
customization, and there should be no need for a separate test
fixture. The CTS test is an exception: it demonstrates how to combine
customization with parameterization.

Prior to TLS1.3 we check that the received record version number is correct.
In TLS1.3 we need to ignore the record version number. This adds a test to

The sources for internal tests were sometimes badly formed, assuming

This adds a test to the OpenSSL test suite to invoke the BoringSSL test
suite.
It assumes you have already compiled the ossl_shim (see previous commit).
It also assumes that you have an environment variable BORING_RUNNER_DIR
set up to point to the ssl/test/runner directory of a checkout of BoringSSL.
This has only been tested with a very old version of BoringSSL (from commit
f277add6c) - since that was the last known checkout where the shim compiles
successfully. Even with that version of BoringSSL this test will fail. There
are lots of Boring tests that are failing for various reasons. Some might
be due to bugs in OpenSSL, some might be due to features that BoringSSL has
that OpenSSL doesn't, some are due to assumptions about the way BoringSSL
behaves that are not true for OpenSSL etc.
To get the verbose BoringSSL test output, run like this:
VERBOSE=1 BORING_RUNNER_DIR=/path/to/boring/ssl/test/runner make \
TESTS="test_external" test

The BoringSSL test suite contains numerous tests which OpenSSL does not.
The BoringSSL test runner uses a shim to launch the library and execute the
tests. This is a version of the BoringSSL shim converted to compile against
OpenSSL instead.
This is primarily based on the work of David Benjamin from the BoringSSL
project who did most of the necessary conversion. It also includes a few
other tweaks for opacity changes etc.
This is based on a *very* old version of BoringSSL from commit f277add6c.
That was the last commit known to work with this patched shim. Later
versions may also work but lots of merge conflicts occur when trying to
bring it up to date.
At the moment this has not been integrated into the build system. There is
a very simple standalone makefile in the ossl_shim directory which should
be executed directly before tyring to use the shim.
