Although SHA512 is currently required to enable SHA384, this
is expected to change in the future. This commit is an
intermediate step towards fully separating SHA384 and SHA512.
check_config is the only module which enforces that SHA512 is
enabled together with SHA384.

Introduce MBEDTLS_X509_INFO to indicate the availability of the
mbedtls_x509_*_info() function and closely related APIs. When this is
not defined, also omit name and description from
mbedtls_oid_descriptor_t, and omit OID arrays, macros, and types that
are entirely unused. This saves several KB of code space.

Add missing tag check for algorithm parameters when comparing the
signature in the description part of the cert against the actual
signature whilst loading a certificate. This was found by a
certificate (created by fuzzing) that openssl would not verify, but
mbedtls would.

RFC5280 does not state that the `revocationDate` should be checked.
In addition, when no time source is available (i.e., when MBEDTLS_HAVE_TIME_DATE is not defined), `mbedtls_x509_time_is_past` always returns 0. This results in the CRL not being checked at all.

Pass the "certificate policies" extension to the callback supplied to
mbedtls_x509_crt_parse_der_with_ext_cb() if it contains unsupported
policies. This allows the callback to fully replicate the behaviour
of the deprecated MBEDTLS_X509_ALLOW_UNSUPPORTED_CRITICAL_EXTENSION
configuration.

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.

Enable MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 in the full config. There's
no reason to keep it out. We weren't testing it at all on the CI.
Add a missing dependency on !MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 to
some test cases that either were testing that v3 extensions are only
accepted in v3 certificates, or where parsing returns a different
error when MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 is enabled.
Add a few positive and negative test cases with
MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 enabled.
Fix one test case with MBEDTLS_X509_ALLOW_EXTENSIONS_NON_V3 where the
intended output of mbedtls_x509_crt_info had changed in
890819a597 but the test case was missed
because it was never executed.

Add dependencies on !MBEDTLS_SHA512_NO_SHA384 to X.509 and SSL unit
tests that use SHA-384 (identified based on having a description that
contains "SHA384" or "SHA-384").
This commit adds multiple test cases to the X.509 CRT parsing test suite
exercising the stack's behaviour when facing CertificatePolicy extensions
that are malformed for a variety of reasons. It follows the same scheme
as in other negative parsing tests: For each ASN.1 component, have test
cases for (a) unexpected tag, (b) missing length, (c) invalid length
encoding, (d) length out of bounds.
This commit modifies the test
X509 CRT ASN1 (TBSCertificate v3, inv CertificatePolicies, data missing)
which exercises the behaviour of the X.509 CRT parser when facing a
CertificatePolicy extension with empty data field.
The following adaptations are made:
- The subject ID and issuer ID are modified to have length 0.
The previous values `aa` and `bb` are OK, but a generic ASN.1
parser will try to interpret them as ASN.1 tags and fail. For
maintainability, it's therefore better to use something that
can be parsed as ASN.1, and an empty ID is the easiest solution
here.
- The TBS part of the certificate wasn't followed by signature
algorithm and signature fields, which makes the test incompatible
with future changes swapping to breadth-first parsing of
certificates.
This commit moves the X.509 negative parsing tests for the
CertificatePolicy extension to the place where negative
testing of other extensions happens.
Judging from its name, the purpose of the test
TBSCertificate v3, ext CertificatePolicies tag, bool len missing
in test_suite_x509parse.data is to exercise the X.509 parsing stack's
behaviour when parsing a CertificatePolicy extension which lacks the
length field of the boolean 'Criticality' value.
However, the test fails at an earlier stage due to a mismatch of inner
and outer length of the explicit ASN.1 extensions structure.
Since we already have tests exercising
- mismatch of inner and outer length in the extensions structure, namely
'X509 CRT ASN1 (TBS, inv v3Ext, inner tag invalid)'
- missing length of the 'Criticality' field in an extension, namely
'X509 CRT ASN1 (TBS, inv v3Ext, critical length missing)'
and since for both tests there's no relevance to the use of the
policy extension OID, the test
'TBSCertificate v3, ext CertificatePolicies tag, bool len missing'
can be dropped.
Tweak test data for one test case to not rely on mbedtls_asn1_get_int
lacking support for leading zeros. Instead, use a number that is
actually out of range for int.
Tweak test data for one test case to not rely on
mbedtls_asn1_get_bitstring_null rejecting bitstrings shorter than two
octets. Instead, try bit strings that are genuinely invalid, or have a
nonzero number of unused bits.
Add a test case with a correct empty signature. This is commented out
because asn1parse currently does not support this. Uncomment it when
asn1parse is updated to support this.

Lengths below 128 Bytes must be encoded as a single 'XX' byte in DER,
but two tests in the X.509 CRT parsing suite used the BER but non-DER
encoding '81 XX' (the first byte 10000001 indicating that the length
is to follow (high bit) and has length 1 byte (low bit)).
Previously, a test exercising the X.509 CRT parser's behaviour
on unexpected tags would use a '00' byte in place of the tag
for the expected structure. This makes reviewing the examples
harder because the binary data isn't valid DER-encoded ASN.1.
This commit uses the ASN.1 NULL TLV '05 00' to test invalid
tags, and adapts surrounding structures' length values accordingly.
This eases reviewing because now the ASN.1 structures are still
well-formed at the place where the mismatch occurs.
