e138dce329 Change to use test-hook-based approach 
Since we are applying hooks transparently to all tests, we cannot setup
and teardown test hooks in the tests. Instead we must do this in the
test wrappers which are used to pre-poison and unpoison memory.

e9efbc2aa5 Error out when get domain_parameters is not supported 
From time being, domain_parameters could not be extracted
from driver. We need to return error to indicate this
situation. This is temporary and would be fixed after #6494.

671f5f539e Change psa_crypto_copy_output error code 
When we are copying output, it makes sense to return
PSA_ERROR_BUFFER_TOO_SMALL since the buffer we are copying to is a user
output buffer.

49a7276c49 Switch error code to more appropriate value 
Since we are internal rather than user-facing,
PSA_ERROR_CORRUPTION_DETECTED makes more sense than
PSA_ERROR_BUFFER_TOO_SMALL. Whilst it really is a buffer that is too
small, this error code is intended to indicate that a user-supplied
buffer is too small, not an internal one.

72ab8ad44a Reject zero-lengths in psa_crypto_copy_and_free() 
Zero-length buffers should be represented in the
psa_crypto_buffer_copy_t struct as NULL if it was created in
psa_crypto_alloc_and_copy(), so reject non-NULL zero-length buffers.

0fee689e57 Simplify zero-length buffers to always be NULL 
Since it is implementation-dependent whether
malloc(0) returns NULL or a pointer, explicitly
represent zero-length buffers as NULL in the
buffer-copy struct, so as to have a uniform
behaviour.
