New function X509_chain_up_ref to dup and up the reference count of
a STACK_OF(X509): replace equivalent functionality in several places
by the equivalent call.

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.

possible to have different stores per SSL structure or one store in
the parent SSL_CTX. Include distint stores for certificate chain
verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN
to build and store a certificate chain in CERT structure: returing
an error if the chain cannot be built: this will allow applications
to test if a chain is correctly configured.

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

that are disabled for this session (as opposed to always disabled by
configuration).

2% less instructions in SIMD code paths, so 2% improvement in average:-)

details in s_client.

Also add ctrl to set client certificate types. If not used sensible values
will be included based on supported signature algorithms: for example if
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
if it exceeded TLS_CT_NUMBER.

Add aliases for SSL_CTX_set_not_resumable_session_callback and
SSL_set_not_resumable_session_callback on top of that.
