ecp_double_add_mxz wrongly does an MPI addition followed by a call to
MOD_MUL instead of MOD_ADD. This is more visible since the
mbedtls_mpi_xxx_mod functions have been added in commit 3b3b34f608
("Replace some macros by functions").
Fix that by using mbedtls_mpi_add_mod instead. The testsuite still
passes after that change.

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.

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.
