Threads lose the mutex between locking the slot and changing the slot's state.
Make it so that threads check if another thread has completed a destruction during this period.
Also fix the issue with the incorrect status variable being used.

The conversion back to signed short is an issue: the uint cast results
in (-1 + UINT_MAX), which is OK. But then that can't be cast back to a
signed value: "if the new type is signed and the value cannot be
represented in it; either the result is implementation-defined or an
implementation-defined signal is raised."

This is the lifetime of the key used to decrypt
the ticket that should be used when parsing a
ticket, not the ticket module lifetime that
may have been changed since the key was
created.

Move PSK ciphersuite selection up to the main
ClientHello parsing function. That way the
ciphersuite selection only happens in this
function.

Regarding the possibility of selecting a
key exchange mode, the check of the ticket
flags is now separated from the check of
the ClientHello content and server
configuration.

For PSK based key exchange modes do not check twice
anymore if they can be selected or not. Check it
only when looping over the offered PSKs to select
one.

If we prefer ephemeral key exchange mode over
the pure PSK one, make sure the resume flag is
disabled as eventually we are not going to
resume a session even if we aimed to at some
point.

If an identity has been determined as a
ticket identity but the ticket is not
usable, do not try to check if the
identity is that of an external
provided PSK.

Improve the values returned by
ssl_tls13_offered_psks_check_identity_match_ticket().
Distinguish between the two following cases:
1) the PSK identity is not a valid ticket identity
2) the PSK identity is a valid ticket identity but
the ticket cannot be used for session resumption.

Fix the value returned by

when there is no ticket parser function defined

When building with -Og (specifically Zephyr with
CONFIG_DEBUG_OPTIMIZATIONS=y) one observes the following warning:
'shared_secret' may be used uninitialized [-Werror=maybe-uninitialized]
Fix this by zero initializing 'shared_secret' similar to the issue
addressed in commit 2fab5c960 ("Work around for GCC bug").
