All OpenSSL tests now test operation with EMS. To test a handshake
*without* EMS we need to pass -Options=-ExtendedMasterSecret which is
only available in OpenSSL 3.1, which breaks a number of other tests.

There was a bug in TestResumption: the first ExpiredSessionTicket was
inserting a ticket far in the future, so the second ExpiredSessionTicket
wasn't actually supposed to fail. However, there was a bug in
checkForResumption->sendSessionTicket, too: if a session was not resumed
because it was too old, its createdAt was still persisted in the next
ticket. The two bugs used to cancel each other out.

Ever since session ticket key rotation was introduced in CL 9072, we've
been including a prefix in every ticket to identify what key it's
encrypted with. It's a small privacy gain, but the cost of trial
decryptions is also small, especially since the first key is probably
the most frequently used.
Also reissue tickets on every resumption so that the next connection
can't be linked to all the previous ones. Again the privacy gain is
small but the performance cost is small and it comes with a reduction in
complexity.

When server and client have mismatch in curve preference, the server will
send HelloRetryRequest during TLSv1.3 PSK resumption. There was a bug
introduced by Go1.19.6 or later and Go1.20.1 or later, that makes the client
calculate the PSK binder hash incorrectly. Server will reject the TLS
handshake by sending alert: invalid PSK binder.

Message marshalling makes use of BytesOrPanic a lot, under the
assumption that it will never panic. This assumption was incorrect, and
specifically crafted handshakes could trigger panics. Rather than just
surgically replacing the usages of BytesOrPanic in paths that could
panic, replace all usages of it with proper error returns in case there
are other ways of triggering panics which we didn't find.
In one specific case, the tree routed by expandLabel, we replace the
usage of BytesOrPanic, but retain a panic. This function already
explicitly panicked elsewhere, and returning an error from it becomes
rather painful because it requires changing a large number of APIs.
The marshalling is unlikely to ever panic, as the inputs are all either
fixed length, or already limited to the sizes required. If it were to
panic, it'd likely only be during development. A close inspection shows
no paths for a user to cause a panic currently.
This patches ends up being rather large, since it requires routing
errors back through functions which previously had no error returns.
Where possible I've tried to use helpers that reduce the verbosity
of frequently repeated stanzas, and to make the diffs as minimal as
possible.
Thanks to Marten Seemann for reporting this issue.

This change makes it easier for clients to debug mutual TLS connection failures. Currently, there are a few situations where invalid client auth leads to a generic "bad certificate" alert. 3 specific situations have a more appropriate TLS alert code, based on the alert descriptions in the appendix of both RFC5246 and RFC8446.
1. The server is configured to require client auth, but no client cert was provided; the appropriate alert is "certificate required". This applies only to TLS 1.3, which first defined the certificate_required alert code.
2. The client provided a cert that was signed by an authority that is not in the server's trusted set of CAs; the appropriate alert is "unknown certificate authority".
3. The client provided an expired (or not yet valid) cert; the appropriate alert is "expired certificate".
Otherwise, we still fall back to "bad certificate".
