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.

The intended logic around MBEDTLS_xxx_ALT is to exclude them from full
because they require the alternative implementation of one or more
library functions, except that MBEDTLS_PLATFORM_xxx_ALT are different:
they're alternative implementations of a platform function and they
have a built-in default, so they should be included in full. Document
this.
Fix a bug whereby MBEDTLS_PLATFORM_xxx_ALT didn't catch symbols where
xxx contains an underscore. As a consequence,
MBEDTLS_PLATFORM_GMTIME_R_ALT and MBEDTLS_PLATFORM_NV_SEED_ALT are now
enabled in the full config. Explicitly exclude
MBEDTLS_PLATFORM_SETUP_TEARDOWN_ALT because it behaves like the
non-platform ones, requiring an extra build-time dependency.
Explicitly exclude MBEDTLS_PLATFORM_NV_SEED_ALT from baremetal
because it requires MBEDTLS_ENTROPY_NV_SEED, and likewise explicitly
unset it from builds that unset MBEDTLS_ENTROPY_NV_SEED.

The presence of these markers in the original code was helpful to me in
figuring out that this portion of the code is auto-generated.
Therefore, I think those are useful and should be present.

If we disable or enable a message locally, it's by design. There's no
need to clutter the Pylint output with this information.

If we take the trouble of using pass, it's because we think the code
is clearer that way. For example, Pylint 2.4 rejects pass in
def foo():
"""Do nothing."""
pass
But relying on a docstring as the sole code is weird, hence the use of
pass.

Simplify the code in minor ways. Each of this changes fixes a warning
from Pylint 2.4 that doesn't appear with Pylint 1.7.

Python 2 is no longer supported upstream. Actively drop compatibility
with Python 2.
Removing the inheritance of a class on object pacifies recent versions
of Pylint (useless-object-inheritance).

The "full" configuration excludes some deprecated or experimental
features. Enable the ones that have tests, don't have extra
requirements and don't turn off some other feature.

The seedfile needs to have the size of the entropy accumulator, which
is 64 bytes (512 bits) since the entropy accumulator uses SHA-512 and
the seed size needs to be the same as the hash output (or larger).
We used to enable MBEDTLS_ENTROPY_FORCE_SHA256 in the full config, so
the entropy accumulator was 256 bits (32 bytes), and therefore a
32-byte seedfile worked. But we no longer turn on this option in the
full config, so the 32-byte seedfile no longer works.
