mbedtls_ecp_gen_key() generates a private key and calculates the public key.
Calculating the public key takes most of the CPU time. But the PSA key store
doesn't store the key, in order to simplify the plumbing when drivers are
involved. So the time spent calculating the public key is a waste.
Instead, call mbedtls_ecp_gen_privkey(), which does not calculate the public
key.
This also saves 8 instructions in a sample arm thumb build.
Resolves#9732.

This helps reducing heap memory usage and, if heap memory is
not used anywhere else in an embedded device, it also reduces
code footprint since there is no need for heap management code
in this case.
A new build symbol is added for this purpose, named
MBEDTLS_PSA_STATIC_KEY_SLOTS. It's disabled by default so that
normal usage of Mbed TLS library is not affected.

This commit refactors tf-psa-crypto to include error_common.h instead of
error.h as these files have been split and the relevant error codes are
now inside error_common.h.

This commit updates the build scripts for error.c generation to be
generated in the Mbed TLS library directory.

This commit splits error.h into error_common.h containing error code
definitions and error.h which contains functions to convert error codes
to error messages.

Use config_adjust_test_accelerators.h
to adjust the configuration needed for
test_psa_crypto_drivers all.sh component
with PSA_CRYPTO_CONFIG enabled.
Signed-off-by: Ronald Cron <ronald.cron@arm.com>
As we move to PSA_CRYPTO_CONFIG always on,
the way to configure the build with both
the builtin drivers and the transparent test
drivers (that are wrappers around the
builtin drivers) cannot be done through the
MBEDTLS_USER_CONFIG_FILE mechanism anymore.
With this mechanism and PSA_CRYPTO_CONFIG
enabled, the PSA_ACCEL_ macros are defined
before including config_adjust_legacy_from_psa.h
and the builtin implementations are removed.
Thus, we will rather define the PSA_ACCEL_
just after the inclusion of
config_adjust_legacy_from_psa.h through the
dedicated config_adjust_test_accelerators.h
header introduced by this commit.

This commit fixes potential buffer overrun in:
- pk_write_rsa_der
- pk_write_ec_pubkey
In both functions, when dealing with opaque keys, there was no
check that the provided buffer was large enough to contain the
key being exported. This commit fixes this problem and it also
adds some testing in test_suite_pkwrite to trigger these checks.

Cleanly reject bits == 0 when calling mbedtls_ecdsa_raw_to_der() and
mbedtls_ecdsa_der_to_raw(). This can plausibly happen when bits is
user-provided data that the calling application doesn't check.
Before this patch, there was typically-benign undefined behavior, such as
adding 0 to a null pointer or calling memcpy on a null pointer with a size
of 0.

Document the return value of mbedtls_ecdsa_raw_to_der() and
mbedtls_ecdsa_der_to_raw().
Document that mbedtls_ecdsa_raw_to_der() has undefined behavior when the
output buffer parameter is null, even with a size of 0.
