EVP_MAC_do_all() in some form.

function was applying TLSv1.2 sig algs rules and did not work correctly if
TLSv1.3 was negotiated.

We refactor tls_choose_sigalg to split it up and create a new function
find_sig_alg which can (optionally) take a certificate and key as
parameters and find an appropriate sig alg if one exists. If the cert and
key are not supplied then we try to find a cert and key from the ones we
have available that matches the shared sig algs.

A default digest of SHA256 was being returned for RSA PSS even if the

This bug had an impact on sig alg selection in libssl. Due to this issue

Fix BN error reporting

Commit ed57f7f935 implemented the macro ERR_raise and updated err.h to use
it. A typo in err.h means that errors in the BN library are mistakenly
attributed to the RSA library.

This was found due to the following error appearing in a travis log:

00:07:CB:13:05:7F:00:00:error:0400006C:rsa routines::data greater than mod
len:crypto/bn/bn_gcd.c:613:

/home/travis/build/openssl/openssl/apps/openssl genrsa -out rsamptest.pem
-primes 5 8192 => 1
not ok 12 - genrsa 8192p5

The line in question (crypto/bn/bn_gcd.c:613) actually looks like this:

        BNerr(BN_F_BN_MOD_INVERSE_NO_BRANCH, BN_R_NO_INVERSE);

The test was checking for that error being raised, but was instead seeing
a different error and thus failing.
