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

Define always psa_key_id_t as defined in the PSA
Cryptography API specification independently of
whether the MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER
configuration file is set or not.
As a consequence, get rid of `psa_app_key_id_t` that is
not needed anymore.
Signed-off-by: Ronald Cron <ronald.cron@arm.com>
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.

Replace server2.crt with server2-sha256.crt which, as the name implies, is
just the SHA-256 version of the same certificate.
Replace server1.crt with cert_sha256.crt which, as the name doesn't imply, is
associated with the same key and just have a slightly different Subject Name,
which doesn't matter in this instance.
The other certificates used in this script (server5.crt and server6.crt) are
already signed with SHA-256.
This change is motivated by the fact that recent versions of GnuTLS (or older
versions with the Debian patches) reject SHA-1 in certificates by default, as
they should. There are options to still accept it (%VERIFY_ALLOW_BROKEN and
%VERIFY_ALLOW_SIGN_WITH_SHA1) but:
- they're not available in all versions that reject SHA-1-signed certs;
- moving to SHA-2 just seems cleaner anyway.

The documentation of mbedtls_pk_wrap_as_opaque is quite clear:
* \param handle Output: a PSA key handle.
* It's the caller's responsibility to call
* psa_destroy_key() on that handle after calling
* mbedtls_pk_free() on the PK context.
But the test failed to call psa_destroy_key().
While at it, also use PSA_DONE(): it ensures that if we fail to destroy the
key, we'll get an explicit error message about it without the need for
valgrind.
This is a preliminary to adding a valgrind-based test for constant-flow code:

This option allows to test the constant-flow nature of selected code, using
MemSan and the fundamental observation behind ctgrind that the set of
operations allowed on undefined memory by dynamic analysers is the same as the
set of operations allowed on secret data to avoid leaking it to a local
attacker via side channels, namely, any operation except branching and
dereferencing.
(This isn't the full story, as on some CPUs some instructions have variable
execution depending on the inputs, most notably division and on some cores
multiplication. However, testing that no branch or memory access depends on
secret data is already a good start.)

The metadata tests depend on the corresponding feature because there
is no guarantee that the metadata is correct if the feature is
disabled. There are metadata test cases for some algorithms and key
types that are declared but not supported. These test cases are
present but can never run.
It is debatable whether having these test cases is a good thing in
case they become runnable in the future, or a bad thing because
they're dead code. We're working on detecting test cases that are
never executed for accidental reasons (e.g. typo in a dependency or
missing configuration on the CI), and having test cases that are
deliberately never executed messes this up. So remove these test
cases. If we do implement the corresponding feature, it'll be easy to
add the corresponding metadata test cases.
The features that had metadata tests but no implementations were:
* SHA-512/256 and SHA-512/224 (hypothetical dependency: MBEDTLS_SHA512_256)

related to the expected values of those outputs.
- Add assertion on fragment_size parameter

In preparation of changing the type of some parameters
of mbedtls_nist_kw_wrap/unwrap() from `char *` to `data_t`
to get rid of the calls to mbedtls_test_unhexify():
- Change the name of parameters and local variables to
clarify which ones are related to the outputs of the
library functions under test and which ones are
related to the expected values of those outputs.

In preparation of changing the type of some parameters of
test_chacha20() from `char *` to `data_t` to get rid of the
calls to mbedtls_test_unhexify():
- Reduce the size of output[] buffer to 375 as its content
is "ASCII expended" into a buffer of 751 bytes.
- Align naming of variables to store and check the
output of mbedtls_chacha20_crypt(). No *dst* variables
anynore, only *output* variables.
- Use two different buffers to store the expected output
of mbedtls_chacha20_crypt() (expected_output_str[]) and
the ASCII string representation of the output of
mbedtls_chacha20_crypt() (output_string[]). Both were
stored in dst_str[] before.

In preparation of changing the type of some parameters
of test_hkdf() from `char *` to `data_t` to get rid of the
calls to mbedtls_test_unhexify():
- Align naming of variables related to the expected okm
- Rename `okm_hex[]` to `okm_string[]`
- Added TEST_ASSERT( expected_okm_len <= sizeof( okm ) ) to check
that the okm[] buffer is large enough for the okm output.

In preparation of changing the type of some parameters
of some test functions from `char *` to `data_t` to get
rid of the calls to mbedtls_test_unhexify():
- Align the name of source data length local variable
with the name of the local variable containing the
source data, respectively src_str and src_str_len.
- Change the type of length, index local variables
from int to size_t.

In preparation of linking common test objects in programs,
add the top-level mbedtls_test target.
This target consists of the common test objects.
It is necessary to declare it at the top-level as both
tests and programs will depend on it and it is necessary
to synchronize the compilation of those objects for tests
and programs for the case of parallel building.

Use the mbedtls_test_ prefix for (c)make variables
related to test common code.
This aligns with the prefix used for the common test
functions.

Parametrize the code that iterates over test case descriptions by the
function to apply on each description.
No behavior change.

Call all.sh for sanity checks, rather than maintain an explicit list.
This was done in .travis.yml in 3c7ffd7a40
Travis has diverged from basic-in-docker. This commit updates the
description of basic-in-docker to no longer refer to Travis. Alignment
with Travis may be desirable but that is beyond the scope of this commit.
