b70a0fd1a5 Key derivation by small input steps: proof-of-concept
Document the new API. Keep the old one.

Implement for HKDF. Use it in a few test cases.

Key agreement is still unchanged.

Add new initializers for cipher operation objects and use them in our

d76f181617 Prefer ASSERT_ALLOC to calloc+TEST_ASSERT in PSA tests
To allocate memory dynamically in a test, call ASSERT_ALLOC which
takes care of calling calloc and of checking for NULL.

1f2aa0e3b0 Remove useless null checks of data_t* parameters
The test framework never passes NULL for a data_t* parameter, so
testing them against NULL is clutter.

40ab95bdbc Remove checks of test parameters against SIZE_MAX
Our code base doesn't even support 16-bit platforms, so those checks
are always trivially true.

f812dcf4ae Rewrap some lines after the macro changes
Change the way some lines are wrapped to cut at a more logical place.
This commit mainly rewrites multi-line calls to TEST_EQUAL, and also a
few calls to PSA_ASSERT.

bdf309ccdb Convert the PSA crypto cryptography tests to the new handle API
Switch from the direct use of slot numbers to handles allocated by
psa_allocate_key.

This commit does not affect persistent key tests except for the one
test function in test_suite_psa_crypto that uses persistent keys
(persistent_key_load_key_from_storage).

The general principle for each function is:
* Change `psa_key_slot_t slot` to `psa_key_handle_t handle`.
* Call psa_allocate_key() before setting the policy of the slot,
  or before creating key material in functions that don't set a policy.
* Some PSA_ERROR_EMPTY_SLOT errors become PSA_ERROR_INVALID_HANDLE
  because there is now a distinction between not having a valid
  handle, and having a valid handle to a slot that doesn't contain key
  material.
* In tests that use symmetric keys, calculate the max_bits parameters
  of psa_allocate_key() from the key data size. In tests where the key
  may be asymmetric, call an auxiliary macro KEY_BITS_FROM_DATA which
  returns an overapproximation. There's no good way to find a good
  value for max_bits with the API, I think the API should be tweaked.

d49a499d03 psa: Implement persistent keys
Allow use of persistent keys, including configuring them, importing and
exporting them, and destroying them.

When getting a slot using psa_get_key_slot, there are 3 scenarios that
can occur if the keys lifetime is persistent:

1. Key type is PSA_KEY_TYPE_NONE, no persistent storage entry:
   -  The key slot is treated as a standard empty key slot
2. Key type is PSA_KEY_TYPE_NONE, persistent storage entry exists:
   -  Attempt to load the key from persistent storage
3. Key type is not PSA_KEY_TYPE_NONE:
   -  As checking persistent storage on every use of the key could
      be expensive, the persistent key is assumed to be saved in
      persistent storage, the in-memory key is continued to be used.

594a330eb7 psa: test: Fix truncation of message by snprintf
We had only allocated 40 bytes for printing into, but we wanted to print 46
bytes. Update the buffer to be 47 bytes, which is large enough to hold what
we want to print plus a terminating null byte.
