d0e755716f Only return VERIFY_FAILED from a single point 
Everything else is a fatal error. Also improve documentation about that for
the vrfy callback.

8af7bfa982 Improve behaviour on fatal errors 
If we didn't walk the whole chain, then there may be any kind of errors in the
part of the chain we didn't check, so setting all flags looks like the safe
thing to do.

7ac50196f3 Add test for limit on intermediate certificates 
Inspired by test code provided by Nicholas Wilson in PR #351.

The test will fail if someone sets MAX_INTERMEDIATE_CA to a value larger than
18 (default is 8), which is hopefully unlikely and can easily be fixed by
running long.sh again with a larger value if it ever happens.

Current behaviour is suboptimal as flags are not set, but currently the goal
is only to document/test existing behaviour.

9fb2828aee Merge branch 'mbedtls-1.3-iotssl-1071-ca-flags' 
Fixes a regression introduced by an earlier commit that modified
x509_crt_verify_top() to ensure that valid certificates that are after past or
future valid in the chain are processed. However the change introduced a change
in behaviour that caused the verification flags MBEDTLS_X509_BADCERT_EXPIRED and
MBEDTLS_BADCERT_FUTURE to always be set whenever there is a failure in the
verification regardless of the cause.

The fix maintains both behaviours:

 * Ensure that valid certificates after future and past are verified
 * Ensure that the correct verification flags are set.

28ba747c8c Add tests for out flags from x509_crt_verify_top() 
The tests load certificate chains from files. The CA chains contain a
past or future certificate and an invalid certificate. The test then
checks that the flags set are BADCERT_EXPIRED or BADCERT_FUTURE.

a5a7f8d464 Fix skipped test dependency in x509parse 
Replace MBEDTLS_ with POLARSSL_ in the test dependency for x509parse,
otherwise tests are always skipped because dependencies are never
satisfied.

463129b7f7 Add missing dependencies to X509 Parse test suite for P-384 curve

curve on the new test cases introduced by ede75f0 and 884b4fc.

1c38550bbd Skip to trusted certs early in the chain 
This helps in the case where an intermediate certificate is directly trusted.
In that case we want to ignore what comes after it in the chain, not only for
performance but also to avoid false negatives (eg an old root being no longer
trusted while the newer intermediate is directly trusted).

see #220

15f1088ef6 Add tests for verify callback 
As we're about to change the chain construction logic, we want to make sure
the callback will still be called exactly when it should, and not on the
(upcoming) ignored certs in the chain.
