ed83ba5321 Add compilation flag to disable certain protocol checks and allow use of
some invalid operations for testing purposes. Currently this can be used
to sign using digests the peer doesn't support, EC curves the peer
doesn't support and use certificates which don't match the type associated
with a ciphersuite.

6dbb6219e7 Make tls1_check_chain return a set of flags indicating checks passed
by a certificate chain. Add additional tests to handle client
certificates: checks for matching certificate type and issuer name
comparison.

Print out results of checks for each candidate chain tested in
s_server/s_client.

3dbc46dfcd Separate client and server permitted signature algorithm support: by default
the permitted signature algorithms for server and client authentication
are the same but it is now possible to set different algorithms for client
authentication only.

18d7158809 Add certificate callback. If set this is called whenever a certificate
is required by client or server. An application can decide which
certificate chain to present based on arbitrary criteria: for example
supported signature algorithms. Add very simple example to s_server.
This fixes many of the problems and restrictions of the existing client
certificate callback: for example you can now clear existing certificates
and specify the whole chain.

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

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.
