Fix a use-after-free in quic_tls.c

The comments in quic_tls.c claimed that the dummybio was never used by
us. In fact that is not entirely correct since we set and cleared the
retry flags on it. This means that we have to manage it properly, and update
it in the event of set1_bio() call on the record layer method.

TLS KeyUpdate messages are not allowed in QUIC

We already disallowed the sending of TLS KeyUpdate messages. We also treat
the receipt of a TLS KeyUpdate message as an unexpected message.

RFC 9001 section 6:
Endpoints MUST treat the receipt of a TLS KeyUpdate message as a connection
error of type 0x010a, equivalent to a fatal TLS alert of unexpected_message;

Unexpected QUIC post-handshake CertificateRequests are a PROTOCOL_VIOLATION

An OpenSSL QUIC client does not send the post_handshake_auth extension.
Therefore if a server sends a post-handsahke CertificateRequest then this
would be treated as a TLS protocol violation with an "unexpected message"
alert code. However RFC 9001 specifically requires us to treat this as
QUIC PROTOCOL_VIOLATION. So we have to translate the "unexpected message"
alert code in this one instance.

Fix an init-deadlock in OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS)

A recursive OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS) call
may happen if an out-of-memory error happens at the first callstack,
and the dead-lock happens at the second callstack, because ossl_err_get_state_int
calls OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS) although that
call is currently already executing.

At least on posix system this causes the process to freeze at this
point, and must be avoided whatever it takes.

The fix is using err_shelve_state around the critical region, which
makes ossl_err_get_state_int return early and not call the recursive
OPENSSL_init_crypto(OPENSSL_INIT_LOAD_CRYPTO_STRINGS).

This can be reproduced with my error injection patch.

The test vector has been validated on the master branch:

Fix handling of the "0:" label in arm-xlate.pl

When $label == "0", $label is not truthy, so `if ($label)` thinks there isn't
a label. Correct this by looking at the result of the s/// command.

Verified that there are no changes in the .S files created during a normal
build, and that the "0:" labels appear in the translation given in the error
report (and they are the only difference in the before and after output).

Fixes #21647

When exporting/importing decoded keys do not use 0 as selection

When decoding 0 as the selection means to decode anything
you get.

However when exporting and then importing the key data 0 as
selection is not meaningful.
So we set it to OSSL_KEYMGMT_SELECT_ALL to make the export/import
function export/import everything that we have decoded.
