Rely on Asan to detect a potential buffer overflow, instead of doing a
manual check. This makes the code simpler and Asan can detect
underflows as well as overflows.

In the cleanup code for persistent_key_load_key_from_storage(), we
only attempt to reopen the key so that it will be deleted if it exists
at that point. It's intentional that we do nothing if psa_open_key()
fails here.

If any of the TEST_ASSERT()s that are before the call to
mbedtls_pk_warp_as_opaque() failed, when reaching the exit label
psa_destroy_key() would be called with an uninitialized argument.

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?

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.

Probably the `W[2 << MBEDTLS_MPI_WINDOW_SIZE]` notation is based on a transcription of 2**MBEDTLS_MPI_WINDOW_SIZE.

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.
From /usr/share/doc/libgnutls30/changelog.Debian.gz:
gnutls28 (3.4.10-4ubuntu1.5) xenial-security; urgency=medium
* SECURITY UPDATE: Lucky-13 issues
[...]
- 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.)

Wrap multi-line string literals in parentheses

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 documentation of mbedtls_pk_wrap_as_opaque is quite clear:
* \param handle Output: a PSA key handle.
* It's the caller's responsibility to call
* psa_destroy_key() on that handle after calling
* mbedtls_pk_free() on the PK context.
But the test failed to call psa_destroy_key().
While at it, also use PSA_DONE(): it ensures that if we fail to destroy the
key, we'll get an explicit error message about it without the need for
valgrind.
This is a preliminary to adding a valgrind-based test for constant-flow code:
we need to make sure the rest of the tests are fully valgrind-clean, which
they weren't.
