Restrict the scope of get_expected_key_size to
generation of key in a secure element or
cryptoprocessor without storage.
For transparent driver, the key buffer size calculation is
for the time being moved to psa_driver_wrapper_generate_key
and will eventually be done by psa_get_key_buffer_size.
Rename the function to get_key_buffer_size to
align its naming with that of psa_get_key_buffer_size.

In case of a secure element or cryptoprocessor with
storage, when generating a key, the key material is
not exported from the secure element or cryptoprocessor
thus there is no need to allocate a buffer in that case.

Preparatory commit to eventually change
psa_generate_key_internal() signature to that of
a PSA driver generate_key entry point.
To be able to change the signature, the buffer to
store the generated key has to be allocated before
the call to psa_generate_key_internal().
This commit moves the allocation and clean-up in
case of error of the buffer to store the generated
key from psa_generate_key_internal() to
psa_generate_key().
This has the nice benefit of factorizing the key
buffer allocation and clean-up.

To be able to change the signature, the buffer to
store the key has to be allocated before the call
to psa_generate_key_internal() thus its size has
to be calculed beforehand as well.
This is the purpose of this commit: to move the
computation of the key size in bytes out of
psa_generate_key_internal().

Small improvements to psa_generate_key_internal()
implementation:
. declare only once the status local variable and
initialize it to PSA_ERROR_CORRUPTION_DETECTED
to improve robustness against FI attacks.
. remove an unnecessary assignment.
. use type local variable instead of its global
variable equivalent.

For calls to gnutls-serv and gnutls-cli where --priority is not
specified, explicitly add the default value: --priority=normal. This is
needed for some tests on Ubuntu 20.04 (gnutls 3.6.13).
For example:
./ssl-opt.sh -f "DTLS fragmenting: gnutls.*1.0"
requires this PR to work on Ubuntu 20.04

Add macros to skip a test case when hitting a
common alternative implementation limitation.
Add a macro for AES-192 and GCM with a nonce
length different from 12 bytes.

Time stamps are useful when the document gets shared around, but they

We care about the exit code of our server, for example if it's
reporting a memory leak after having otherwise executed correctly.
We don't care about the exit code of the servers we're using for
interoperability testing (openssl s_server, gnutls-serv). We assume
that they're working correctly anyway, and they return 1 (gnutls-serv)
or die by the signal handle the signal (openssl) when killed by a
signal.

In psa_generate_derived_key_internal() an error case was returning
directly rather than jumping to the exit label, which meant that an
allocated buffer would not be free'd.

Make sure MBEDTLS_PSA_CRYPTO_CLIENT is defined
when MBEDTLS_PSA_CRYPTO_C is defined and guard
PSA client code only with MBEDTLS_PSA_CRYPTO_CLIENT.
The definition of MBEDTLS_PSA_CRYPTO_CLIENT is done
in crypto_types.h before the definition of
psa_key_attributes_t. That way as PSA crypto client
code is related to key attributes we can be quite
confident that MBEDTLS_PSA_CRYPTO_CLIENT will be
defined when needed.

Move test macros previously located in `suites/helpers.function` to
`include/test/macros.h`. This makes these test infrastructure macros
available for use in other parts of the test infrastructure at compile
time as opposed to run time.
This commit is a simple cut and paste from one file to the other.
