Note: if the CERT based stores are not set then the parent SSL_CTX
store is used to retain compatibility with existing behaviour.

Also add ctrl to set client certificate types. If not used sensible values

we don't include any DSA signing algorithms the DSA certificate type is
omitted.
Fix restriction in old code where certificate types would be truncated

supported signature algorithms. Add very simple example to s_server.
This fixes many of the problems and restrictions of the existing client

and specify the whole chain.

Add new "cert_flags" field to CERT structure and include a "strict mode".
This enforces some TLS certificate requirements (such as only permitting
certificate signature algorithms contained in the supported algorithms
extension) which some implementations ignore: this option should be used
with caution as it could cause interoperability issues.
