Fix PSA code and unit tests for the unit tests
to pass with key identifiers encoding owner
identifiers.
The changes in PSA code just make the enablement
of key identifiers encoding owner identifiers
platform independent. Previous to this commit,
such key identifiers were used only in the case
of PSA SPM platforms.

With PSA crypto v1.0.0, a volatile key identifier may
contain a owner identifier but no file is associated
to it. Thus rename the type psa_key_file_id_t to
mbedtls_svc_key_id_t to avoid a direct link with a
file when a key identifier involves an owner
identifier.
The new type name is prefixed by mbedtls to highlight
that the type is specific to Mbed TLS implementation
and not defined in the PSA Cryptography API
specification.
The svc in the type name stands for service as this
is the key identifier type from the point of view of
the service providing the Cryptography services.
The service can be completely provided by the present
library or partially in case of a multi-client service.
As a consequence rename as well:
. MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER to
MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
. PSA_KEY_ID_INIT to MBEDTLS_SVC_KEY_ID_INIT
. PSA_KEY_FILE_GET_KEY_ID to MBEDTLS_SVC_KEY_ID_GET_KEY_ID
. psa_key_file_id_make to mbedtls_svc_key_id_make

The purpose of this commit and the following is for
psa_key_id_t to always be as defined by the PSA
Cryptography API specification.
Currently psa_key_id_t departs from its specification
definition when MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER
configuration flag is set. In that configuration, it is set
to be equal to psa_key_file_id_t which in that configuration
encodes an owner identifier along the key identifier.
Type psa_key_file_id_t was meant to be the key identifier type
used throughout the library code. If
MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER is set it
includes both a key and owner identifier, otherwise it is
equal to psa_key_id_t.
It has not been the key identifier type throughout the
library so far because when the PSA Cryptography
specification was developped the library Doxygen
documentation was used to generate the PSA Cryptography API
specification thus the need to use psa_key_id_t and not
psa_key_file_id_t.
As this constraint does not hold anymore, move
to psa_key_file_id_t as the key identifier type throughout
the library code.
By the way, this commit updates the key identifier
initialization in the tests to be compatible with a
composit key identifier. A psa_key_id_make()
inline function is introduced to initialize key
identifiers (composit ot not) at runtime.

An early draft of the PSA crypto specification required multipart
operations to keep working after destroying the key. This is no longer
the case: instead, now, operations are guaranteed to fail. Mbed TLS
does not comply yet, and still allows the operation to keep going.
Stop testing Mbed TLS's non-compliant behavior.

Rely on Asan to detect a potential buffer overflow, instead of doing a
manual check. This makes the code simpler and Asan can detect
underflows as well as overflows.

In the cleanup code for persistent_key_load_key_from_storage(), we
only attempt to reopen the key so that it will be deleted if it exists
at that point. It's intentional that we do nothing if psa_open_key()
fails here.

PSA Crypto was checking the byte length of a to-be-imported public ECP key
against the expected length for Weierstrass keys, forgetting that
Curve25519/Curve448 exists.

Create an include folder dedicated to include files for
tests. With the upcoming work on tests for PSA crypto
drivers the number of includes specific to tests is going
to increase significantly thus create a dedicated folder.
Don't put the include files in the include folder but in
include/test folder. This way test headers can be included
using a test/* path pattern as mbedtls and psa headers
are included using an mbedtls/* and psa/* path pattern.
This makes explicit the scope of the test headers.
Move the existing includes for tests into include/test and
update the code and build systems (make and cmake)
accordingly.

Adds an additional boundary check to the test parameter bytes_arg in
generate_random() in test_suite_psa_crypto.function.
This is to check against a possible underflow, and to avoid a warning,
"argument ... exceeds maximum object size", (-Werror=alloc-size-larger-than)
that GCC 7 generates.

Remove the values of curve encodings that are based on the TLS registry
and include the curve size, keeping only the new encoding that merely
encodes a curve family in 8 bits.
Keep the old constant names as aliases for the new values and
deprecate the old names.
psa_hash_compare is tested for good cases and invalid-signature cases
in hash_compute_compare. Also test invalid-argument cases. Also run a
few autonomous test cases with valid arguments.
We're going to create some edge cases where the attributes of a key
are not bitwise identical to the attributes passed during creation.
Have a test function ready for that.
When MBEDTLS_TEST_DEPRECATED is defined, run some additional tests to
validate deprecated PSA macros. We don't need to test deprecated
features extensively, but we should at least ensure that they don't
break the build.
Add some code to component_build_deprecated in all.sh to run these
tests with MBEDTLS_DEPRECATED_WARNING enabled. The tests are also
executed when MBEDTLS_DEPRECATED_WARNING and
MBEDTLS_DEPRECATED_REMOVED are both disabled.
Rename some macros and functions related to signature which are
changing as part of the addition of psa_sign_message and
psa_verify_message.
perl -i -pe '%t = (
PSA_KEY_USAGE_SIGN => PSA_KEY_USAGE_SIGN_HASH,

PSA_ASYMMETRIC_SIGN_OUTPUT_SIZE => PSA_SIGN_OUTPUT_SIZE,

Consolidate the invalid-handle tests from test_suite_psa_crypto and
test_suite_psa_crypto_slot_management. Start with the code in
test_suite_psa_crypto_slot_management and adapt it to test one invalid
handle value per run of the test function.
After passing some inputs, try getting one byte of output, just to
check that this succeeds (for a valid sequence of inputs) or fails
with BAD_STATE (for an invalid sequence of inputs). Either output a
1-byte key or a 1-byte buffer depending on the test data.
The test data was expanded as follows:
* Output key type (or not a key): same as the SECRET input if success
is expected, otherwise NONE.
* Expected status: PSA_SUCCESS after valid inputs, BAD_STATE after any
invalid input.
This commit only makes derive_input more flexible so that the key
derivation API can be tested with different key types and raw data for
each input step. The behavior of the test cases remains the same.
Test the behavior of the getter/setter functions.
Test that psa_get_key_slot_number() reports a slot number for a key in
a secure element, and doesn't report a slot number for a key that is
not in a secure element.
Test that psa_get_key_slot_number() reports the correct slot number
for a key in a secure element.
Add tests that call psa_generate_random() (possibly via
psa_generate_key()) with a size that's larger than
MBEDTLS_CTR_DRBG_MAX_REQUEST. This causes psa_generate_random() to
fail because it calls mbedtls_ctr_drbg_random() without taking the
maximum request size of CTR_DRBG into account.
Non-regression test for #206
Conflict resolution:
* `scripts/config.pl`:
Take the exclusion of `MBEDTLS_PSA_CRYPTO_SE_C` from the API branch.
Take the removal of `MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C` (obsolete) from
the development branch.
* `tests/scripts/all.sh`:
Multiple instances of factoring a sequence of `config.pl` calls into
a mere `config.pl baremetal` in the development branch, and a change in
the composition of `baremetal` in the API branch. In each case, take the
version from development.
* `tests/suites/test_suite_psa_crypto_slot_management.function`:
A function became non-static in development and disappeared in the API
branch. Keep the version from the API branch. Functions need to be
non-static if they're defined but unused in some configurations,
which is not the case for any function in this file at the moment.
* `tests/suites/test_suite_psa_crypto.function`:
Consecutive changes in the two branches, reconciled.
65528 bits is more than any reasonable key until we start supporting
post-quantum cryptography.
This limit is chosen to allow bit-sizes to be stored in 16 bits, with
65535 left to indicate an invalid value. It's a whole number of bytes,
which facilitates some calculations, in particular allowing a key of
exactly PSA_CRYPTO_MAX_STORAGE_SIZE to be created but not one bit
more.
As a resource usage limit, this is arguably too large, but that's out
of scope of the current commit.
Test that key import, generation and derivation reject overly large
sizes.
Move the "core attributes" to a substructure of psa_key_attribute_t.
The motivation is to be able to use the new structure
psa_core_key_attributes_t internally.
Make some functions non-static, to avoid Wunused function warnings. Make
a function scoped variable block scoped instead, to avoid Wunused
variable warnings in some configurations.
