When TEST_EQUAL fails, show the two numerical values in the test log (only
with host_test). The values are printed in hexa and signed decimal.
The arguments of TEST_EQUAL must now be integers, not pointers or floats.
The current implementation requires them to fit in unsigned long long
Signed values no larger than long long will work too. The implementation
uses unsigned long long rather than uintmax_t to reduce portability
concerns. The snprintf function must support "%llx" and "%lld".
For this purpose, add room for two lines of text to the mbedtls_test_info
structure. This adds 154 bytes of global data.

Test the following combinations:
* 1024-bit key, SHA-256, salt=0
* 1024-bit key, SHA-256, salt=31 (1 byte shorter than standard)
* 1024-bit key, SHA-256, salt=32 (standard length)
* 1024-bit key, SHA-256, salt=94 (maximum possible length)
* 1024-bit key, SHA-512, salt=61 (1 byte shorter than standard)
* 1024-bit key, SHA-512, salt=62 (standard = maximum possible length)
* 528-bit key, SHA-512, salt=0 (only possible length)
Test psa_verify_hash() for both PSA_ALG_RSA_PSS and PSA_ALG_RSA_PSS_ANY_SALT
with all of these combinations. For psa_verify_message(), just test once
with the standard length and once with a different length.
Note that as of this commit, both PSA_ALG_RSA_PSS and
PSA_ALG_RSA_PSS_ANY_SALT accept any salt length during verification, hence
all the new test cases are positive.
The verify test cases were generated using the Python script below.

This is a variant of PSA_ALG_RSA_PSS which currently has exactly the same
behavior, but is intended to have a different behavior when verifying
signatures.
In a subsequent commit, PSA_ALG_RSA_PSS will change to requiring the salt
length to be what it would produce when signing, as is currently documented,
whereas PSA_ALG_RSA_PSS_ANY_SALT will retain the current behavior of
allowing any salt length (including 0).
Changes in this commit:
* New algorithm constructor PSA_ALG_RSA_PSS_ANY_SALT.
* New predicates PSA_ALG_IS_RSA_PSS_STANDARD_SALT (corresponding to
PSA_ALG_RSA_PSS) and PSA_ALG_IS_RSA_PSS_ANY_SALT (corresponding to
PSA_ALG_RSA_PSS_ANY_SALT).
* Support for the new predicates in macro_collector.py (needed for
generate_psa_constant_names).

Declare all AES and DES functions that return int as needing to have

A DES or AES block operation can fail in alternative implementations of
mbedtls_internal_aes_encrypt() (under MBEDTLS_AES_ENCRYPT_ALT),
mbedtls_internal_aes_decrypt() (under MBEDTLS_AES_DECRYPT_ALT),
mbedtls_des_crypt_ecb() (under MBEDTLS_DES_CRYPT_ECB_ALT),
mbedtls_des3_crypt_ecb() (under MBEDTLS_DES3_CRYPT_ECB_ALT).
A failure can happen if the accelerator peripheral is in a bad state.
Several block modes were not catching the error.
This commit does the following code changes, grouped together to avoid
having an intermediate commit where the build fails:
* Add MBEDTLS_CHECK_RETURN to all functions returning int in aes.h and des.h.
* Fix all places where this causes a GCC warning, indicating that our code
was not properly checking the result of an AES operation:
* In library code: on failure, goto exit and return ret.
* In pkey programs: goto exit.
* In the benchmark program: exit (not ideal since there's no error
message, but it's what the code currently does for failures).
* In test code: TEST_ASSERT.
* Changelog entry.

This commit adds four known answer tests for TLS 1.3 record protection
from the following sources:
- RFC 8448 "Example Handshake Traces for TLS 1.3"
- tls13.ulfheim.net "The New Illustrated TLS Connection"
It extends the test coverage of the existing record protection tests
in the following ways:
- The existing record protection tests hand-craft record transform
structures; the new tests use the function
mbedtls_ssl_tls13_populate_transform()
from library source to create an TLS 1.3 transform from raw
key material and connection information.
- The existing record protection tests only check that encryption
and decryption are inverse to each other; as such, they don't
catch non-compliant implementations of encryption and decryption
which happen to be inverse to each other. By adding a known answer
test for TLS 1.3 record protection, can gain confidence that our
implementation is indeed standards-compliant.

Instances of `mbedtls_ssl_session` represent data enabling session resumption.
With the introduction of TLS 1.3, the format of this data changes. We therefore
need TLS-version field as part of `mbedtlsl_ssl_session` which allows distinguish
1.2 and 1.3 sessions.
This commit introduces such a TLS-version field to mbedtls_ssl_session.
The change has a few ramifications:
- Session serialization/deserialization routines need to be adjusted.
This is achieved by adding the TLS-version after the header of
Mbed TLS version+config, and by having the subsequent structure
of the serialized data depend on the value of this field.
The details are described in terms of the RFC 8446 presentation language.
The 1.2 session (de)serialization are moved into static helper functions,
while the top-level session (de)serialization only parses the Mbed TLS
version+config header and the TLS-version field, and dispatches according
to the found version.
This way, it will be easy to add support for TLS 1.3 sessions in the future.
- Tests for session serialization need to be adjusted
- Once we add support for TLS 1.3, with runtime negotiation of 1.2 vs. 1.3,
we will need to have some logic comparing the TLS version of the proposed session
to the negotiated TLS version. For now, however, we only support TLS 1.2,
and no such logic is needed. Instead, we just store the TLS version in the
session structure at the same point when we populate mbedtls_ssl_context.minor_ver.
The change introduces some overlap between `mbedtls_ssl_session.minor_ver` and
`mbedtls_ssl_context.minor_ver`, which should be studied and potentially resolved.
However, with both fields being private and explicitly marked so, this can happen
in a later change.

Tests for psa_cipher_encrypt and psa_cipher_decrypt functions.
The psa_cipher_encrypt function takes no parameter for IV and always generates
it therefore there will be a randomness in the calculation and cannot be
validated by comparing the actual output with the expected output.
The function is tested by:
- doing a prtially randomized test with an encryption then a decryption
and validating the input with output of the decryption
- validating against the multipart encryption
The combination of this two methods provides enough coverage like a
