The updated shim has the ability to skip tests using unimplemented flags.
This should reduce the number of test failures.

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.

shared library extension.  This is not the case for Mac OS X, which
uses .dylib.  Instead of this, have the test recipe find out the

Pre 1.1.0, 'make test' would set the environment variable
OPENSSL_DEBUG_MEMORY to "on".  This got lost when translating the old

The Unix and Windows linkers appear to simply ignore if any symbol is
defined multiple times in different object files and libraries.

The VMS linker, on the other hand, warns about it, loud and clear.  It
will still create the executable, but does so screaming.  So we
complicate things by saving the linker output, look through all the
errors and warnings, and if they are only made up of %LINK-W-MULDEF,
we let it pass, otherwise we output the linker output and raise the
same exit code we got from the linker.
