b86e684ed4 Move/remove param validation in mbedtls_rsa_rsaes_pkcs1_v15_encrypt 
- The validity of the input and output parameters is checked by
  parameter validation.
- A PRNG is required in public mode only (even though it's also
  recommended in private mode), so move the check to the
  corresponding branch.

5b89c09273 Add check for iv_off in AES-CFB128 and AES-OFB 
The check is mandatory as skipping it results in buffer overread of arbitrary
size.

998a358529 Make a check more explicit in aes.c 
The check was already done later when calling ECB, (as evidenced by the tests
passing, which have a call with data_unit set to NULL), but it's more readable
to have it here too, and more helpful when debugging.

23fd2bdb94 Update some documentation related to key slots 
Some of the documentation is obsolete in its reference to key slots
when it should discuss key handles. This may require a further pass,
possibly with some reorganization of error codes.

Update the documentation of functions that modify key slots (key
material creation and psa_set_key_policy()) to discuss how they affect
storage.

fa4135b135 Move more slot management functions to the proper module 
Move psa_load_persistent_key_into_slot,
psa_internal_make_key_persistent and psa_internal_release_key_slot to
the slot management module.

Expose psa_import_key_into_slot from the core.

After this commit, there are no longer any functions declared in
psa_crypto_slot_management.h and defined in psa_crypto.c. There are
still function calls in both directions between psa_crypto.c and
psa_crypto_slot_management.c.

66fb126e87 Move the key slot array to the slot management module 
Move the key slot array and its initialization and wiping to the slot
management module.

Also move the lowest-level key slot access function psa_get_key_slot
and the auxiliary function for slot allocation
psa_internal_allocate_key_slot to the slot management module.

moving the responsibility for some fields to
psa_crypto_slot_management.c.

3f10812ff9 Use the library-wide zeroize function 
Since Mbed TLS 2.10, there is a single copy of
mbedtls_platform_zeroize for the whole library instead of one per
module. Update the PSA crypto module accordingly.

2f060a8ea5 Rename key_slot_t to psa_key_slot_t in psa_crypto.c 
That way it'll be ok to add it to an internal header so as to use it
in multiple source modules.

4a044739a8 Fix the build without persistent storage

NOT_SUPPORTED.

c5487a8892 Drop support for psa_key_slot_t in psa_crypto.c 
This commit finishes the removal of support for direct access to key
slots in psa_crypto.c.

This marks the end of the necessary phase of the transition to key
handles. The code should subsequently be refactored to move key slot
management from psa_crypto.c to psa_crypto_slot_management.c.
