668a78d952 Added sppecific test cases for mbedtls_rsa_rsassa_pss_sign_ext()
- all positibe test cases were sampled from the CAVP test suite
  (SigGenPSS_186-2.txt, SigGenPSS_186-3.txt)
  Only kept one representative for each triple (modlen, sha, saltlen)
- two extra test cases were added to cover the maximum salt length
  (slen=olen-slen-2 and slen=(olen-slen-2)-1)
- in rsa.c, the salt intermediate buffer was too small to cover cases
  where slen > hlen. So reworked the code to generate the salt in the
  encoded message directly. This has the advantage to remove a memcpy
  and a memset.

0cbdc61171 Bump version to Mbed TLS 2.25.0
Executed ./scripts/bump_version.sh --version 2.25.0 --so-crypto 6

Increasing the SO version of the crypto library, because the openless
API improvement came with API/ABI incompatibilities. For example
    - the size of psa_key_handle_t changed
    - the type of a parameter in 18 public functions has changed from
      psa_key_handle_t to mbedtls_svc_key_id_t

557b8d663a Remove Extraneous bytes from buffer post pem write
In order to remove large buffers from the stack, the der data is written
into the same buffer that the pem is eventually written into, however
although the pem data is zero terminated, there is now data left in the
buffer after the zero termination, which can cause
mbedtls_x509_crt_parse to fail to parse the same buffer if passed back
in. Patches also applied to mbedtls_pk_write_pubkey_pem, and
mbedtls_pk_write_key_pem, which use similar methods of writing der data
to the same buffer, and tests modified to hopefully catch any future
regression on this.

70edd689a8 cipher_auth_xxcrypt(): fix some null pointer handling
Make sure that if a buffer is allowed to be empty, a null pointer is
accepted if the buffer length is 0. This was already the case for most
but not all arguments to mbedtls_cipher_auth_{en,de}crypt{,_ext}.

Make sure to pass NULL for an empty buffer in the tests.

4592bd8982 Fix broken testing on numbers that may be greater than MPI_MAX_SIZE
Previously `mbedtls_mpi_exp_mod` was tested with values that were over
`MBEDTLS_MPI_MAX_SIZE` in size. This is useful to do as some paths are only
taken when the exponent is large enough however, on builds where
`MBEDTLS_MPI_MAX_SIZE` is under the size of these test values.

This fix turns off these tests when `MBEDTLS_MPI_MAX_SIZE` is too small to
safely test (notably this is the case in config-thread.h).

e146bdcff9 Fix cases where exponentiation was not fully tested
In two test cases, the exponentiation computation was not being fully tested
as when A_bytes (the base) == N_bytes (the modulus) -> A = N. When this is the
case A is reduced to 0 and therefore the result of the computation will always
be 0.

This fixes that issue and therefore increases the test coverage to ensure
different computations are actually being run.

6aceb51e43 Support set *_drbg reseed interval before seed
mbedtls_ctr_drbg_set_reseed_interval() and
mbedtls_hmac_drbg_set_reseed_interval() can now be called before
their seed functions and the reseed_interval value will persist.
Previously it would be overwritten with the default value.

*_drbg_reseed_interval is now set in init() and free().

mbedtls_ctr_drbg_free() and mbedtls_hmac_drbg_free() now
reset the drbg context to the state immediately after init().

Tests:
- Added test to check that DRBG reseeds when reseed_counter
reaches reseed_interval, if reseed_interval set before seed
and reseed_interval is less than MBEDTLS_CTR_DRBG_RESEED_INTERVAL.
