Add option to dynamically load libcrypto.so.*
This adds OQS_DLOPEN_OPENSSL build option to use OpenSSL through dynamically loaded libcrypto.so.* with dlopen, instead of linking to the library at build time. That way the applications could use their favorite implementation of common cryptographic primitives without pulling in the OpenSSL as a hard dependency. Signed-off-by: Daiki Ueno <[email protected]>
