225010fdf7 Remove lifetime parameter from psa_open_key
Change the scope of key identifiers to be global, rather than
per lifetime. As a result, you now need to specify the lifetime of a
key only when creating it.

ee32cd4af6 Slot management tests: more robust storage purge
Record what key ids have been used in a test case and purge them. The
cleanup code no longer requires the key identifiers used in the tests
to be in a certain small range.

4440688a69 Update key management tests to use attributes
Remove test cases which are no longer relevant because they involve a
slot which is allocated but not filled with key material.

87a5e565f4 Rename functions that inject key material to an allocated handle
This commit starts a migration to a new interface for key creation.
Today, the application allocates a handle, then fills its metadata,
and finally injects key material. The new interface fills metadata
into a temporary structure, and a handle is allocated at the same time
it gets filled with both metadata and key material.

This commit was obtained by moving the declaration of the old-style
functions to crypto_extra.h and renaming them with the to_handle
suffix, adding declarations for the new-style functions in crypto.h
under their new name, and running

    perl -i -pe 's/\bpsa_(import|copy|generator_import|generate)_key\b/$&_to_handle/g' library/*.c tests/suites/*.function programs/psa/*.c
    perl -i -pe 's/\bpsa_get_key_lifetime\b/$&_from_handle/g' library/*.c tests/suites/*.function programs/psa/*.c

Many functions that are specific to the old interface, and which will
not remain under the same name with the new interface, are still in
crypto.h for now.

All functional tests should still pass. The documentation may have
some broken links.

57ab721d8a Test psa_copy_key
Split the testing into tests that exercise policies in
test_suite_psa_crypto and tests that exercise slot content (slot
states, key material) in test_suite_psa_crypto_slot_management.

Test various cases of source and target policies with and without
wildcards. Missing: testing of the policy constraint on psa_copy_key
itself.

Test several key types (raw data, AES, RSA). Test with the
source or target being persistent.

Add failure tests (incompatible policies, source slot empty, target
slot occupied).

d40c1fbd50 Don't require a type and size when creating a key slot
Remove the type and bits arguments to psa_allocate_key() and
psa_create_key(). They can be useful if the implementation wants to
know exactly how much space to allocate for the slot, but many
implementations (including ours) don't care, and it's possible to work
around their lack by deferring size-dependent actions to the time when
the key material is created. They are a burden to applications and
make the API more complex, and the benefits aren't worth it.

Change the API and adapt the implementation, the units test and the
sample code accordingly.

70261c513a psa: Add initializers for key policies
Add new initializers for key policies and use them in our docs, example
programs, tests, and library code. Prefer using the macro initializers
due to their straightforwardness.

f812dcf4ae Rewrap some lines after the macro changes
Change the way some lines are wrapped to cut at a more logical place.
This commit mainly rewrites multi-line calls to TEST_EQUAL, and also a
few calls to PSA_ASSERT.

reindenting (but not wrapping lines):

0174be2c17 Move the PSA_ASSERT macro to the common helpers file
It's potentially useful in all PSA test suites, of which there are now
several.

4a044739a8 Fix the build without persistent storage
Add missing guards on MBEDTLS_PSA_CRYPTO_STORAGE_C.

c5487a8892 Drop support for psa_key_slot_t in psa_crypto.c
This commit finishes the removal of support for direct access to key
slots in psa_crypto.c.

This marks the end of the necessary phase of the transition to key
handles. The code should subsequently be refactored to move key slot
management from psa_crypto.c to psa_crypto_slot_management.c.
