Steven Cooreman 0789783c17 Migrate MAC setup/abort calls into the software driver
Step 1/x in moving the driver. Separate commits should make for easier
review.
Additional changes on top of just moving code:
* Added a sanity check on the key buffer size for CMAC.
* Transfered responsibility for resetting the core members of the
  PSA MAC operation structure back to the core (from the driver
  wrapper layer)

Change the driver calling logic for psa_sign/verify_messsage
The changed logic is to try a sign-message driver (opaque or transparent);
if there isn't one, fallback to builtin sofware and do the hashing,
then try a sign-hash driver. This will enable to the opaque driver
to fallback to software.

Ronald Cron b0737dab26 tests: psa: Simplify key buffer size calculation
Move the key buffer size calculation code under
tests to avoid check-names.sh to complain about
"likely macros with typos".

This removes the calculation of key buffer
sizes for the test driver from the wrapper based on
static size data. But the code is still there in test
code to be used when we go back to work on the
generation of the driver wrapper.

Steven Cooreman a1ce2f2675 Rename test driver lifetime to location
The macro always meant 'location', but was mistakenly named 'lifetime'.
Naming it location instead makes much more sense, and drives home the
conceptual differences between location and lifetime values.

Steven Cooreman 1a0fbacde1 Refactor opaque key handling in the test driver
Builtin key support for the test driver is always compiled in, and no
  longer guarded by MBEDTLS_PSA_CRYPTO_BUILTIN_KEYS.
Parsing the key slot from the buffer by cast and assign instead of memcmp.
For exporting keys, the test driver no longer reaches into the key
  identifier in order to check whether a key is builtin, but rather
  assumes so based on the key buffer length. It's the driver's
  responsibility to be able to detect the key material it returned as part
  of the get_builtin_key operation.

For cipher multi-part operations, dispatch based on

Mbed TLS software implementation (viewed as a driver).
Also use the driver identifier to check that an
cipher operation context is active or not.

This aligns the way hash and cipher multi-part
operations are dispatched.

Steven Cooreman 830aff2a98 Restructure the way driver contexts are declared
Drivers (both built-in and external) need to declare their context
structures in a way such that they are accessible by the
to-be-autogenerated crypto_driver_contexts.h file. That file lives in
include/psa, which means all builtin driver context structure
declarations also need to live in include/psa.

Steven Cooreman dbf8ceda54 Change the way driver context structures are used
Apparently there's a goal to make the PSA Crypto core free from
dynamic memory allocations. Therefore, all driver context structures
need to be known at compile time in order for the core to know their
final size.

This change defines & implements for hashing operations how the context
structures get defined.
