 * Identities
 * ----------
 *
 * All series start with 1, to allow 0 to be an array terminator.
 * For any FUNC identity, we also provide a function signature typedef
 * and a static inline function to extract a function pointer from a
 * OSSL_DISPATCH element in a type safe manner.
 *
 * Names:
 * for any function base name 'foo' (uppercase form 'FOO'), we will have
 * the following:
 * - a macro for the identity with the name OSSL_FUNC_'FOO' or derivatives
 *   thereof (to be specified further down)
 * - a function signature typedef with the name OSSL_FUNC_'foo'_fn
 * - a function pointer extractor function with the name OSSL_FUNC_'foo'
 */

/*
 * Helper macro to create the function signature typedef and the extractor
 * |type| is the return-type of the function, |name| is the name of the
 * function to fetch, and |args| is a parenthesized list of parameters
 * for the function (that is, it is |name|'s function signature).
 * Note: This is considered a "reserved" internal macro. Applications should
 * not use this or assume its existence.

/*-
 * Key management
 *
 * The Key Management takes care of provider side key objects, and includes
 * all current functionality to create them, destroy them, set parameters
 * and key material, etc, essentially everything that manipulates the keys
 * themselves and their parameters.
 *
 * The key objects are commonly referred to as |keydata|, and it MUST be able
 * to contain parameters if the key has any, the public key and the private
 * key.  All parts are optional, but their presence determines what can be
 * done with the key object in terms of encryption, signature, and so on.
 * The assumption from libcrypto is that the key object contains any of the
 * following data combinations:
 *
 * - parameters only
 * - public key only
 * - public key + private key
 * - parameters + public key
 * - parameters + public key + private key
 *
 * What "parameters", "public key" and "private key" means in detail is left
 * to the implementation.  In the case of DH and DSA, they would typically
 * include domain parameters, while for certain variants of RSA, they would
 * typically include PSS or OAEP parameters.
 *
 * Key objects are created with OSSL_FUNC_keymgmt_new() and destroyed with
 * OSSL_FUNC_keymgmt_free().  Key objects can have data filled in with
 * OSSL_FUNC_keymgmt_import().
 *
 * Three functions are made available to check what selection of data is
 * present in a key object: OSSL_FUNC_keymgmt_has_parameters(),
 * OSSL_FUNC_keymgmt_has_public_key(), and OSSL_FUNC_keymgmt_has_private_key(),
