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.

Currently the new component in all.sh fails because
mbedtls_ssl_cf_memcpy_offset() is not actually constant flow - this is on
purpose to be able to verify that the new test works.

The tests are supposed to be failing now (in all.sh component
test_memsan_constant_flow), but they don't as apparently MemSan doesn't
complain when the src argument of memcpy() is uninitialized, see
https://github.com/google/sanitizers/issues/1296
The next commit will add an option to test constant flow with valgrind, which
will hopefully correctly flag the current non-constant-flow implementation.

This paves the way for a constant-flow implementation of HMAC checking, by
making sure that the comparison happens at a constant address. The missing
step is obviously to copy the HMAC from the secret offset to this temporary
buffer with constant flow, which will be done in the next few commits.

Before this commit, certs.c had a copy of a different version of
tests/data_files/server2-sha256.crt (from the then development branch)
which was generated by cert_write. Update certs.c with the new
tests/data_files/server2-sha256.crt which is also generated by
cert_write.
The new copy has the same size as the old copy so there is no concern
about existing application binaries relying on the size. (The old
tests/data_files/server2-sha256.crt had a different size because it
had been generated by openssl and so had slightly different content.)

I might be wrong, but lcc's optimizer is curious about this,
and I am too: shouldn't we free allocated stuff correctly
before exiting `dh_genprime` in this certain point of code?

server2-sha256.crt had the issuer ON and CN encoded as UTF8String, but the
corresponding CA certificate test-ca_cat12.crt had them encoded as
PrintableString. The strings matched, which is sufficient according to RFC
5280 §7.1 and RFC 4518 §2.1. However, GnuTLS 3.4.10 requires the strings to
have the same encoding, so it did not accept that the
UTF8String "PolarSSL Test CA" certificate was signed by the
PrintableString "PolarSSL Test CA" CA.
Since Mbed TLS 2.14 (specifically ebc1f40aa0
merged via https://github.com/ARMmbed/mbedtls/pull/1641), server2-sha256.crt
is generated by Mbed TLS's own cert_write program, which emits a
PrintableString. In older versions, this file was generated by OpenSSL,
which started emitting UTF8String at some point.
4f928c0f37 merged via
https://github.com/ARMmbed/mbedtls/pull/2418 fixed this for the SHA-1
certificate which was used at the time. The present commit applies the same
fix for the SHA-256 certificate that is now in use.

The test certificate used for clients in compat.sh, cert_sha256.crt,
had the issuer ON and CN encoded as UTF8String, but the corresponding
CA certificate test-ca_cat12.crt had them encoded as PrintableString.

PrintableString "PolarSSL Test CA" CA.

For some reason, RIPEMD160, SHA224 and SHA384 were not supported.
This fixes the build recipes for tests/data_files/cert_sha224.crt and

Replace server2.crt with server2-sha256.crt which, as the name implies, is
just the SHA-256 version of the same certificate.
Replace server1.crt with cert_sha256.crt which, as the name doesn't imply, is
associated with the same key and just have a slightly different Subject Name,
which doesn't matter in this instance.
The other certificates used in this script (server5.crt and server6.crt) are
already signed with SHA-256.
This change is motivated by the fact that recent versions of GnuTLS (or older
versions with the Debian patches) reject SHA-1 in certificates by default, as
they should. There are options to still accept it (%VERIFY_ALLOW_BROKEN and
%VERIFY_ALLOW_SIGN_WITH_SHA1) but:
- they're not available in all versions that reject SHA-1-signed certs;
- moving to SHA-2 just seems cleaner anyway.

Recent GnuTLS packages on Ubuntu 16.04 have them disabled.

- debian/patches/CVE-2018-1084x-4.patch: hmac-sha384 and sha256
ciphersuites were removed from defaults in lib/gnutls_priority.c,
tests/priorities.c.
Since we do want to test the ciphersuites, explicitly re-enable them in the
server's priority string. (This is a no-op with versions of GnuTLS where those
are already enabled by default.)

For explicit proxy commands (included with `-p "$P_PXY <args>` in the test
case), it's the test's writer responsibility to handle IPv6; only fix the

A lot of DTLS test are timing-sensitive, especially those that contain
assertions about retransmission. Sometimes some DTLS test fails intermittently
on the CI with no clear apparent reason; we need more information in the log
to understand the cause of those failures.
Adding a proxy means we'll get timing information from the proxy logs.
An alternative would be to add timing information to the debug output of
ssl_server2 and ssl_client2. But that's more complex because getting
sub-second timing info is outside the scope of the C standard, and our current
timing module only provides a APi for sub-second intervals, not absolute time.
Using the proxy is easier as it's a single point that sees all messages, so
elapsed time is fine here, and it's already implemented in the proxy output.
