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?

They are used to generate cert_md*.crt.
Regenerate cert_md5.crt which had previously been generated for a
different key.

It wasn't working when invoking programs/x509/cert_write or
programs/x509/cert_req due to relying on the current directory rather
than the location of the makefile.

Discover hash algorithms automatically rather than hard-coding a list,
as was previously done in cert_write.

For some reason, RIPEMD160, SHA224 and SHA384 were not supported.
This fixes the build recipes for tests/data_files/cert_sha224.crt and
tests/data_files/cert_sha384.crt .

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.

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.)

As a result, the copyright of contributors other than Arm is now
acknowledged, and the years of publishing are no longer tracked in the
source files.
Also remove the now-redundant lines declaring that the files are part of
MbedTLS.

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
proxy command when we're auto-adding it.

This is a convenience for when we get log files from failed CI runs, or attach
them to bug reports, etc.

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.

In the entries (mbedtls_x509_crl_entry values) on the list constructed
by mbedtls_x509_crl_parse_der(), set entry->raw.tag to
(SEQUENCE | CONSTRUCTED) rather than to the tag of the first ASN.1
element of the entry (which happens to be the tag of the serial
number, so INTEGER or INTEGER | CONTEXT_SPECIFIC). This is doesn't
really matter in practice (and in particular the value is never used
in Mbed TLS itself), and isn't documented, but at least it's
consistent with how mbedtls_x509_buf is normally used.
The primary importance of this change is that the old code tried to
access the tag of the first element of the entry even when the entry
happened to be empty. If the entry was empty and not followed by
anything else in the CRL, this could cause a read 1 byte after the end
of the buffer containing the CRL.
The test case "X509 CRL ASN1 (TBSCertList, single empty entry at end)"
hit the problematic buffer overflow, which is detected with ASan.
Credit to OSS-Fuzz for detecting the problem.

Add a few more negative test cases for mbedtls_x509_crl_parse.
The test data is manually adapted from the existing positive test case
"X509 CRL ASN1 (TBSCertList, sig present)" which decomposes as
