e39bdaa0ed Specialize some wording from the specification 
Some of the material was originally the PSA specification, and
discusses how different implementations might behave. Replace such
statements by a description of how Mbed TLS behaves.

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

6a530e8d26 Random driver: make initial_entropy_size mandatory 
If a random driver has a built-in entropy source and doesn't need an
external entropy source, make the driver author declare this
explicitly, rather than it being a less secure default.

8d5092c11f get_random: no output on error 
The get_random entry point was allowed to return partial data on both
PSA_SUCCESS and PSA_ERROR_INSUFFICIENT_ENTROPY, but there was no
meaningful difference between the two. Keep it simple: PSA_SUCCESS is
success but can be partial, and PSA_ERROR_INSUFFICIENT_ENTROPY is an
error with no output.
