8eea3ae860 Fix undeclared deps on MBEDTLS_CTR_DRBG in tests
While at it, declare deps on ENTROPY as well.

A non-regression test will be added in a follow-up commit.

Backport 2.7: Guard from undefined behaviour in case of an INT_MAX max_pathlen

3fd9297658 Guard from undefined behaviour in case of an INT_MAX max_pathlen
When parsing a certificate with the basic constraints extension
the max_pathlen that was read from it was incremented regardless
of its value. However, if the max_pathlen is equal to INT_MAX (which
is highly unlikely), an undefined behaviour would occur.
This commit adds a check to ensure that such value is not accepted
as valid. Relevant tests for INT_MAX and INT_MAX-1 are also introduced.
Certificates added in this commit were generated using the
test_suite_x509write, function test_x509_crt_check. Input data taken
from the "Certificate write check Server1 SHA1" test case, so the generated
files are like the "server1.crt", but with the "is_ca" field set to 1 and
max_pathlen as described by the file name.

75d26b5d17 unit tests: Indicate missing unmet dependencies
The identifiers of the unmet dependencies of a test case are
stored in a buffer of fixed size that can be potentially too
small to store all the unmet dependencies. Indicate in test
report if some unmet dependencies are missing.

355bbc0e70 Test each failure mode of pk_parse_key_pkcs1_der()
(Only the top-level ones, ie, for each call to eg asn1_get_mpi(), ensure
there's at least one test case that makes this call fail in one way, but don't
test the various ways to make asn1_get_mpi fail - that should be covered
elsewhere.)

- the new checks added by the previous commits needed exercising
- existing tests sometimes had wrong descriptions or where passing for the
  wrong reason (eg with the "length mismatch" test, the function actually
failed before reaching the length check)
- while at it, add tests for the rest as well

The valid minimal-size key was generated with:

openssl genrsa 128 2>/dev/null | openssl rsa -outform der 2>/dev/null | xxd -p

MBEDTLS_MEMORY_DEBUG but all are useful even without it. So enable

04d45c98e8 Clarify that the "FATAL" message is expected
The test case "Memory buffer small buffer" emits a message
"FATAL: verification of first header failed". In this test case, it's
actually expected, but it looks weird to see this message from a
passing test. Add a comment that states this explicitly, and modify
the test description to indicate that the failure is expected, and
change the test function name to be more accurate.

c3b376e2f2 Change mbedtls_mpi_cmp_mpi_ct to check less than
The signature of mbedtls_mpi_cmp_mpi_ct() meant to support using it in
place of mbedtls_mpi_cmp_mpi(). This meant full comparison functionality
and a signed result.

To make the function more universal and friendly to constant time
coding, we change the result type to unsigned. Theoretically, we could
encode the comparison result in an unsigned value, but it would be less
intuitive.

Therefore we won't be able to represent the result as unsigned anymore
and the functionality will be constrained to checking if the first
operand is less than the second. This is sufficient to support the
current use case and to check any relationship between MPIs.

The only drawback is that we need to call the function twice when
checking for equality, but this can be optimised later if an when it is
needed.

b729e1b9ba CTR_DRBG: support set_entropy_len() before seed()
mbedtls_ctr_drbg_seed() always set the entropy length to the default,
so a call to mbedtls_ctr_drbg_set_entropy_len() before seed() had no
effect. Change this to the more intuitive behavior that
set_entropy_len() sets the entropy length and seed() respects that and
only uses the default entropy length if there was no call to
set_entropy_len().

The former test-only function mbedtls_ctr_drbg_seed_entropy_len() is
no longer used, but keep it for strict ABI compatibility.

d56ca658ab entropy_nv_seed: cope with SHA-256
This test case was only executed if the SHA-512 module was enabled and
MBEDTLS_ENTROPY_FORCE_SHA256 was not enabled, so "config.pl full"
didn't have a chance to reach it even if that enabled
MBEDTLS_PLATFORM_NV_SEED_ALT.

Now all it takes to enable this test is MBEDTLS_PLATFORM_NV_SEED_ALT
and its requirements, and the near-ubiquitous MD module.
