Delegate command line handling for many common options in s_client/s_server to
the SSL_CONF APIs.
This is complicated a little because the SSL_CTX structure is not available
when the command line is processed: so just check syntax of commands initially
and store them, ready to apply later.
Add ctrl and utility functions to retrieve raw cipher list sent by client in
client hello message. Previously this could only be retrieved on an initial
connection and it was impossible to determine the cipher IDs of any uknown
ciphersuites.

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.

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.
(backport from HEAD)
Add support for certificate stores in CERT structure. This makes it
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.
(backport from HEAD)
New function ssl_set_client_disabled to set masks for any ciphersuites
that are disabled for this session (as opposed to always disabled by
configuration).
(backport from HEAD)
Add new ctrl to retrieve client certificate types, print out
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.
(backport from HEAD)
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.
(backport from HEAD)
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.
(backport from HEAD)
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.
(backport from HEAD)
Only store encoded versions of peer and configured signature algorithms.
Determine shared signature algorithms and cache the result along with NID
equivalents of each algorithm.
(backport from HEAD)
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.
(backport from HEAD)
Revert incompatible OCSP_basic_verify changes.
Make partial chain chekcing work with EE certificates only.
Remove unneeded -trust_other option from tocsp.
