The new naming scheme consistently usese the `OSSL_FUNC_` prefix for all functions which are dispatched between the core and providers. This change includes in particular all up- and downcalls, i.e., the dispatched functions passed from core to provider and vice versa. - OSSL_core_ -> OSSL_FUNC_core_ - OSSL_provider_ -> OSSL_FUNC_core_ For operations and their function dispatch tables, the following convention is used: Type | Name (evp_generic_fetch(3)) | ---------------------|-----------------------------------| operation | OSSL_OP_FOO | function id | OSSL_FUNC_FOO_FUNCTION_NAME | function "name" | OSSL_FUNC_foo_function_name | function typedef | OSSL_FUNC_foo_function_name_fn | function ptr getter | OSSL_FUNC_foo_function_name | Reviewed-by: Richard Levitte <levitte@openssl.org> (Merged from https://github.com/openssl/openssl/pull/12222)
