1f0db80c78 psa: cipher: Fix symmetric key management
Symmetric key management is not intended to be
delegated to drivers. Thus, key management code
for a given symmetric key type should be included
in the library whether or not the support for
cryptographic operations based on that type of
symmetric key may be delegated to drivers.

8287e6b078 psa: cipher: Add utility functions
Isolate the Mbed TLS cipher driver interfaces.
Do the actual cipher operations in utility
functions that are just called by the interface
functions.

The utility functions are intended to be also called
by the cipher test driver interface functions (to be
introduced subsequently) and allow to test the case
where cipher operations are fully accelerated with no
fallback (component test_psa_crypto_config_basic of
all.sh).

49fafa98b1 psa: cipher: Dispatch based on driver identifier
For cipher multi-part operations, dispatch based on
the driver identifier even in the case of the
Mbed TLS software implementation (viewed as a driver).
Also use the driver identifier to check that an
cipher operation context is active or not.

This aligns the way hash and cipher multi-part
operations are dispatched.

To run succesfully the test
"PSA sign: invalid algorithm for ECC key" of
test_suite_psa_crypto when ECDSA support is not included
in the library, always return INVALID_ARGUMENT
in case of an ECC key not used for ECDSA, whether
ECDSA support is present or not.

Then apply the same logic to RSA sign RSA and RSA/ECC
verify for the sake of consistency.

a1684f42d3 PSA: Reject curves that are not enabled in the PSA configuration
If an elliptic curve was enabled in the Mbed TLS classic API (#define
MBEDTLS_ECP_DP_xxx), but not enabled in the PSA configuration (#define
PSA_WANT_ECC_xxx), it would still work if you tried to use it through
PSA.

This is generally benign, but could be a security issue if you want to
disable a curve in PSA for some security reason (such as a known bug
in its implementation, which may not matter in the classic API if Mbed
TLS is running in a secure enclave and is only reachable from
untrusted callers through the PSA API). More urgently, this broke
test_suite_psa_crypto_not_supported.generated.

So if a curve is not enabled in the PSA configuration, ensure that
it's treated as unsupported through the PSA software implementation.

830aff2a98 Restructure the way driver contexts are declared
Drivers (both built-in and external) need to declare their context
structures in a way such that they are accessible by the
to-be-autogenerated crypto_driver_contexts.h file. That file lives in
include/psa, which means all builtin driver context structure
declarations also need to live in include/psa.

d48d5c6615 Fix size_t and longlong specifiers for MinGW
MinGW and older windows compilers cannot cope with %zu or %lld (there is
a workaround for MinGW, but it involves linking more code, there is no
workaround for Windows compilers prior to 2013). Attempt to work around
this by defining printf specifiers for size_t per platform for the
compilers that cannot use the C99 specifiers.

3a5a107fa7 Correct fix for potential truncation
This was a false positive caused by the compiler seeing the %08lx
specifiers and judging the output on that, rather than the numbers being
fed in. Given these are going to be maximum 32 bit numbers, then better
to use %08x, which keeps -Wformat-truncation=2 happy as well.
