Multiple copies of the ENGINE will cause problems when it is cleaned up as
the methods are stored in static structures which will be overwritten and
freed up more than once.

Set static methods to NULL when the ENGINE is freed so it can be reloaded.

some invalid operations for testing purposes. Currently this can be used
to sign using digests the peer doesn't support, EC curves the peer

Add code to SSL_trace to include support for printing out keys.

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.

certificates: checks for matching certificate type and issuer name

Print out results of checks for each candidate chain tested in

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.
