tests/api.c: add error_test() adapted from wolfcrypt/test/test.c, checking all error strings for expected presence/absence and length, called from existing test_wolfSSL_ERR_strings().
wolfssl/ssl.h, wolfssl/error-ssl.h, and wolfssl/wolfcrypt/error-crypt.h:
* move several negative error return codes from ssl.h to error-ssl.h,
* renumber them to conform to existing sequence, and
* include error-ssl.h from ssl.h;
* add special-case WOLFSSL_DEBUG_TRACE_ERROR_CODES macros for WOLFSSL_FAILURE;
* add missing WOLFSSL_API attribute to wc_backtrace_render().
add numerous WC_NO_ERR_TRACE()s to operand error code uses, cleaning up error traces in general, and particularly when WOLFSSL_DEBUG_TRACE_ERROR_CODES_ALWAYS.
* crypto lib (36),
* crypto test&benchmark (20),
* TLS lib (179),
* examples (122),
* linuxkm (3),
* tests/api.c (2272).
* added POSIX definitions for XFEOF(), XFERROR(), and XCLEARERR(), currently with no-op fallbacks for !POSIX.
* added missing file handle checks in testsuite/testsuite.c:file_test() and tests/utils.h:copy_file().
* added fixes and suppression around tests/api.c:test_wolfSSL_SMIME_read_PKCS7().
* added various fixes in examples/asn1/asn1.c and examples/pem/pem.c.
asn1.c: Allow sample to build without coding (base64 decoding).
set_curves_list(): function for ECC, Ed25519, Ed448 but this block of
code is ECC only. Fixed #ifdef protection.
wolfSSL_CTX_set1_curves_list and wolfSSL_set1_curves_list also available
when Curve25519/Curve448 compiled in but not ECC.
Moved E[CD][25519||448] APIs to pk.c
Move public key PEM APIs to pk.c.
Move wolfSSL loading and using of private keys and certificates to
ssl_load.c
Move PKCS#7 and PKCS#12 APIs to ssl_p7p12.c.
Move session and session cache APIs to ssl_sess.c.
Other minor fixes.
As per https://datatracker.ietf.org/doc/html/rfc7250#section-3 Figure 1,
the RPK is a single ASN.1_subjectPublicKeyInfo, whereas X509 certificates
etc. are transmitted as a certificate list (even if there is only 1).
This is for (D)TLS1.2 transfers, and this PR fixes this.
As per https://datatracker.ietf.org/doc/html/rfc8446#section-4.4.2 all
certificates (both RPK and Z509) are transferred using a certificate list.
Update examples client to support RPK certificates.
