A few functions were changed from returning void to returning int three
commits ago. Make sure their callers check the return values.
This commits was basically a matter of declaring newly-int-returning
functions MBEDTLS_CHECK_RETURN_CRITICAL and then fixing the resulting
warnings. A few functions had to be made int in the process; they were
applied the same process as well.

Check ciphersuite list length parity once,
mainly to enable the possibility of getting
out of the loop of the ciphersuites whenever
we want.

On resumption, after the psk identity is matched, we
should check if psk and/or psk_ephemeral, which are
allowed by session ticket, are valid to be selected.

When determining the key exchange mode, ticket_flags
should be checked so that the server won't select the
kex mode that is forbidden from session ticket.

Return MBEDTLS_ERR_ERROR_GENERIC_ERROR when ticket_flags
are not compatible with advertised key exchange mode.

Ticket flags is quite generic and may make sense in the
future versions of TLS or even in TLS 1.2 with new
extensions. This change remane the ticket_flags helper
functions with more generic `mbedtls_ssl_session` prefix
instead of `mbedtls_ssl_tls13_session`.

Handshake parameter field, tls13_kex_mode is only valid when
MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_SOME_PSK_ENABLED is set.
So, any functions / calls should be guarded by this macros.

Move the kex mode check in ticket_flags to
ssl_tls13_offered_psks_check_identity_match_ticket and add new error
'MBEDTLS_ERR_SSL_TICKET_INVALID_KEX_MODE' to indicate the check
failure.

The server check if the ticket_flags is compatible with the advertised
key exchange modes in Pre-Shared Key Exchange Modes extension. The
incompatible ticket should be mark as not matched.

Use MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_SOME_PSK_ENABLED
instead of MBEDTLS_KEY_EXCHANGE_SOME_PSK_ENABLED to guard
code specific to one of the TLS 1.3 key exchange mode with
PSK.

Use MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_EPHEMERAL_ENABLED
instead of MBEDTLS_KEY_EXCHANGE_WITH_CERT_ENABLED to guard
code specific to the TLS 1.3 ephemeral key exchange mode.
Use it also for the dependencies of TLS 1.3 only tests
relying on ephemeral key exchange mode, but for
tests in tls13-kex-modes.sh where the change is done
later using all
MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_.*ENABLED macros.
