Truncate input hashes to curve private key size as that is all that is required
for the internal implementation.

After moving the MPIs used to output from the operation into the complete
function, I failed to move the accompanying free as well.

Move the obfuscation of the internal library only returning a delta of ops done
into the driver wrapper, thus meaning driver wrapper and API call both return
absolute values of work done. Document the differences at the internal
implementation level.

If an error occurs, calling any function on the same operation should return
PSA_ERROR_BAD_STATE, and we were not honouring that for all errors. Add extra
failure tests to try and ratify this.

For sign and verify, the pointer passed in to the hash is not guaranteed to
remain valid inbetween calls, thus we need to store the hash in the
operation. Added a test to ensure this is the case.

Make it clear that these functions reset the number of ops, and remove
statements that say they have no effect.

Test for not having determnistic ECDSA was also being run when no ECDSA, and
this fails earlier. Fixed this and added a specific test for no ECDSA. Also
fixed (swapped) incorrect test descriptions.

Also make previous changes apply to both interruptible sign hash operation
structures rather than just the one as it was.

Test for unsupported deterministic ECDSA was originally passing due to
incorrect code, fixing the code unfortunately broke the test.

Only 2 options were really possible anyway - complete in 1 op, or somewhere
between 2 and max ops. Anything else we cannot test due to implementation
specifics.

Make sure the number of ops is tested in the interruptible failure tests,
should they get through the interruptible loop part.

Set the psa level global anyway, regardless of having a built in
implementation, to match the set function. Also, ensure that value returned
is the same as value passed in, irregardless of internal implementation
requirements.

Ensure that num_ops is cleared when manual abort is called, but obviously not
when an operation just completes, and test this.

Move to accumulate ops in context rather than attempting to read straight out
of structures due to structure ops getting reset per operation, and also
issues with _abort clearing internal data. Fix usage of size_t in structures

Make public the versions of ECSDA sign and verify which return raw signatures
rather than returning ASN.1 encoded signatures, in order to use them for the
internal implemention of psa_sign/verify_hash_interruptible.
