d4a258a08f Improve PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE validation 
We want to check:
1. actual output <= PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE (the output fits
   if the caller uses the key-specific buffer size macro)
2. actual output <= PSA_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE (the output fits
   if the caller uses the generic buffer size macro)
3. PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE <= PSA_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE
   (consistency in the calculation)

We were only testing (1) and (2). Test (3) as well. (1) and (3) together
imply (2) so there's no need to test (2).

cd00d7f724 test PSA key derivation: add positive and negative cases for mixed-psk 
Mix-PSK-to-MS test vectors are generated using python-tls library:
https://github.com/python-tls/tls

Steps to generate test vectors:
1. git clone git@github.com:python-tls/tls.git
2. cd tls
3. python3 setup.py build
4. sudo python3 setup.py install
5. Use the python script below to generate Master Secret (see description for details):

Script to derive MS using mixed PSK to MS algorithm.

Script can be used to generate expected result for mixed PSK to MS tests.

286c314ae3 cipher_alg_without_iv: also test multipart decryption 
For multipart encrpytion, call psa_cipher_finish(). This is not actually
necessary for non-pathological implementations of ECB (the only currently
supported IV-less cipher algorithm) because it requires the input to be a
whole number of blocks and non-pathological implementations emit the output
block from update() as soon as an input block is available. But in principle
a driver could delay output and thus require a call to finish().

9b9b614a02 cipher_encrypt_alg_without_iv: validate size macros independently 
Validate the size macros directly from the output length in the test data,
rather than using the value returned by the library. This is equivalent
since the value returned by the library is checked to be identical.

Enforce that SIZE() <= MAX_SIZE(), in addition to length <= SIZE(). This is
stronger than the previous code which merely enforced length <= SIZE() and
length <= MAX_SIZE().
