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.

800e1cd969 Additional workaround for PR#2771
If OPENSSL_MAX_TLS1_2_CIPHER_LENGTH is set then limit the size of client
ciphersuites to this value. A value of 50 should be sufficient.

293706e72c Partial workaround for PR#2771.
Some servers hang when presented with a client hello record length exceeding
255 bytes but will work with longer client hellos if the TLS record version
in client hello does not exceed TLS v1.0. Unfortunately this doesn't fix all
cases...
