Cover the Poly1305 ConstantCompare tag check in ChachaAEADDecrypt that
no existing test was hitting (VERIFY_MAC_ERROR never expected in the
suite). A memio-based TLS 1.2 handshake over
ECDHE-RSA-CHACHA20-POLY1305 completes, the server's IORecv is then
replaced with a wrapper that flips the final byte of the next record
body so the forged Poly1305 tag no longer matches. The server's
wolfSSL_read must surface VERIFY_MAC_ERROR.
Covers the HandleResumeHistory check that RFC 7627 Section 5.3 requires:
if the original session used Extended Master Secret, the server MUST
abort when a resumption ClientHello is received without EMS. The new
memio test performs a TLS 1.2 handshake with EMS, saves the session,
disables EMS on a fresh client, resumes with the saved session, and
asserts the server returns EXT_MASTER_SECRET_NEEDED_E.
tests/api/test_ossl_x509.c, tests/api/test_ossl_x509.h: add test_wolfssl_local_IsValidFQDN().
src/internal.c: in MatchDomainName(), when WOLFSSL_LEFT_MOST_WILDCARD_ONLY, do pattern matching and case folding only if target string validates as an FQDN.
When WOLF_CRYPTO_CB_AES_SETKEY is enabled and a CryptoCB callback
imports the AES key into a Secure Element (aes->devCtx != NULL), the
TLS-layer copy in keys->{client,server}_write_key has no further
consumer: the software key schedule is not populated on offload.
ForceZero it in SetKeysSide() per provisioned side.
The static IVs (keys->{client,server}_write_IV and
keys->aead_{enc,dec}_imp_IV) are left intact because BuildTls13Nonce()
reads aead_{enc,dec}_imp_IV on every record (RFC 8446 Section 5.3).
Scope: TLS 1.3, non-DTLS, non-QUIC. DTLS 1.3 needs the write keys
in Dtls13EpochCopyKeys; TLS 1.2 needs them for rehandshake; QUIC is
untouched pending audit.
Add two memio tests (test_wc_CryptoCb_Tls13_Key_{Zero_After_Offload,
No_Zero_Without_Offload}) that pin AES-GCM and check key / IV state
after the handshake and a KeyUpdate round.

Implement RFC8773bis (draft-ietf-tls-8773bis-13)
cert_with_extern_psk for TLS 1.3, including protocol checks
and API support.
Includes unit tests for API and handshake behavior as well
as tests in the testsuite using extended examples.
* Fix OOB heap reads via TLSX_ExtractEch() by preemptively rejecting oversized
SNI names in TLSX_UseSNI().
* In TLSX_EchChangeSNI(), don't attempt to truncate if an oversized name is
seen, just return error.
* Move definition of WOLFSSL_HOST_NAME_MAX to an ungated context in ssl.h, and
use it consistently in tls.c, eliminating the duplicative
WOLFSSL_HOST_NAME_MAX.
