Richard Levitte 7c664b1f1b DESERIALIZER: Add deserializers for the rest of our asymmetric key types
To be able to implement this, there was a need for the standard
EVP_PKEY_set1_, EVP_PKEY_get0_ and EVP_PKEY_get1_ functions for
ED25519, ED448, X25519 and X448, as well as the corresponding
EVP_PKEY_assign_ macros.  There was also a need to extend the list of
hard coded names that EVP_PKEY_is_a() recognise.

Along with this, OSSL_FUNC_keymgmt_load() are implemented for all
those key types.

The deserializers for these key types are all implemented generically,
in providers/implementations/serializers/deserializer_der2key.c.

Adding new libraries

When adding a new sub-library to OpenSSL, assign it a library number ERR_LIB_XXX, define a macro XXXerr() (both in err.h), add its name to ERR_str_libraries[] (in crypto/err/err.c), and add ERR_load_XXX_strings() to the ERR_load_crypto_strings() function (in crypto/err/err_all.c). Finally, add an entry:

L      XXX     xxx.h   xxx_err.c

to crypto/err/openssl.ec, and add xxx_err.c to the Makefile. Running make errors will then generate a file xxx_err.c, and add all error codes used in the library to xxx.h.

Additionally the library include file must have a certain form. Typically it will initially look like this:

#ifndef HEADER_XXX_H
#define HEADER_XXX_H

#ifdef __cplusplus
extern "C" {
#endif

/* Include files */

#include <openssl/bio.h>
#include <openssl/x509.h>

/* Macros, structures and function prototypes */


/* BEGIN ERROR CODES */

The BEGIN ERROR CODES sequence is used by the error code generation script as the point to place new error codes, any text after this point will be overwritten when make errors is run. The closing #endif etc will be automatically added by the script.

The generated C error code file xxx_err.c will load the header files stdio.h, openssl/err.h and openssl/xxx.h so the header file must load any additional header files containing any definitions it uses.
