This part can fail, so it shouldn't be intermixed with the part that
can't fail and is there to ensure all structures are in a clean state,
should any error happen.
Fortunately, the part that should be split out already had a function
doing it: reset_checksum. Also, handshake_params_init had only one
calling site to update.

There are three family of functions: update_checksum, calc_verify,
calc_finished, that perform hashing operations and were returning void
so far. This is not correct, as hashing functions can return errors (for
example, on hardware failure when accelerated). Change them to return
int.
This commit just changes the types: for now the functions always return
0, and their return value is not checked; this will be fixed in the
next few commits.
There is a related function in TLS 1.3,
mbedtls_ssl_reset_transcript_for_hrr, which also handles hashes, and
already returns int but does not correctly check for errors from hashing
functions so far, it will also be handled in the next few commits.
There's a special case with handshake_params_init: _init functions
should return void, so we'll need to split out the part that can return
errors, see the next commit.

When ticket_flags used as parameter, use unsigned int,
instead of uint8_t or mbedtls_ssl_tls13_ticket_flags.Also
remove the definition of mbedtls_ssl_tls13_ticket_flags.

Some PSA curves' symbols (PSA_WANT_) were not matching the corresponding
MBEDTLS_ECP_DP_. This was fixed together with the removal of extra code
when DEBUG_C is not enabled.

It might happen that the psa_pake_output() function returns
elements which are not exactly 32 or 65 bytes as expected, but
1 bytes less.
As a consequence, insted of hardcoding the expected value for
the length in the output buffer, we write the correct one as
obtained from psa_pake_output()

NEW_SESSION_TICKETS* are processed in handshake_step.
Change the stop condition from `mbedtls_ssl_is_handshake_over`
to directly check.

Inlined functions might cause the compiled code to have different sizes
depending on the usage and this not acceptable in some cases.
Therefore read/write functions used in the initial key exchange are
moved to a standard C file.
