0f39bab0df Function tls1_check_ec_server_key is now redundant as we make 
appropriate checks in tls1_check_chain.

Dr. Stephen Henson
d61ff83be9 Add new "valid_flags" field to CERT_PKEY structure which determines what 
the certificate can be used for (if anything). Set valid_flags field
in new tls1_check_chain function. Simplify ssl_set_cert_masks which used
to have similar checks in it.

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.

0f229cce65 Add support for application defined signature algorithms for use with 
TLS v1.2. These are sent as an extension for clients and during a certificate
request for servers.

TODO: add support for shared signature algorithms, respect shared algorithms
when deciding which ciphersuites and certificates to permit.
