Merge remote-tracking branch 'psa/pr/13' into feature-psa

Conflicts:
	library/psa_crypto.c
	tests/suites/test_suite_psa_crypto.data
	tests/suites/test_suite_psa_crypto.function

All the conflicts are concurrent additions where the order doesn't
matter. I put the code from feature-psa (key policy) before the code
from PR #13 (key lifetime).
