Add tests for version/ciphersuite sanity checks

The previous commits added sanity checks for where the max enabled protocol
version does not have any configured ciphersuites. We should check that we
fail in those circumstances.

Don't overwrite the alert value if there is no alert to send

The function tls_early_post_process_client_hello() was overwriting the
passed "al" parameter even if it was successful. The caller of that
function, tls_post_process_client_hello(), sets "al" to a sensible default
(HANDSHAKE_FAILURE), but this was being overwritten to be INTERNAL_ERROR.
The result is a "no shared cipher" error (and probably other similar errors)
were being reported back to the client with an incorrect INTERNAL_ERROR
alert.

test: don't make it more complicated than necessary.

Original rationale behind using write in testutil was to accommodate
no-stdio builds. But is there evidence that no-stdio users would have
write or pre-defined meaning for file descriptors 1 and 2? Correct
answer is to provide way for no-stdio users who want to exercise
tests to plug in own BIO, not to make assumption that they have write.
And since we don't have to make such assumption, we can as well go
for simplest that works with standard library as specified by C

Add support for custom signature parameters

Many signature types define the digest and public key type by a single OID
such as ecdsa_with_sha256.

Some types (RSA-PSS for example) use a single OID to indicate the signature
scheme and additional parameters are encoded in the AlgorithmIdentifier.

Add an X509_SIG_INFO structure to contain details about the signature type:
specifically the digest algorithm, public key algorithm, security bits and
various flags. This supports both existing algorithms and more complex
types.

Add accessors for the structure and a special case that retrieves signature
information from a certificate.
