tested in test_suite_constant_time.function.

These are very CPU-intensive, so make it easy to skip them. And conversely,
make it easy to run them without the growing body of SSL tests.

The last line of programs/psa/key_ladder_demo.c is of the following
form:
#endif /* Very long comment ... */
Uncrustify tries to reduce the length:
#endif \
/* Very long comment ... */
and causes a compiler error as there is a continuation line with no
actual code in it. Work around this by linewrapping the comment
in advance.

Running make from programs/fuzz didn't set any optimization flags (running
make from programs or from the root inherited the parent's optimization
flags). Default to -O2.
There were no -W flags. Default to -Wall -Wextra, but not -Werror in line
with the other makefiles.

All builds using ASAN_CFLAGS were with Asan but no optimisation, making
them particularly slow. Indeed, we were overwriting CFLAGS which
defaults to -O2 and not using any -O in the replacement. (CMake already has
optimisations on with ASan.)
While at it, also remove -Wall -Wextra which are redundant as they are
already part of WARNING_CFLAGS which we are not overwriting.

The test cases using tcp_client.pl are failing only on Travis's bionic and
focal systems (I can't reproduce the failure locally). Exclude them.

Don't use an all.sh component because there isn't one that does what we
want (modern Clang with ASan, and test everything).
* We need to set CC explicitly or tweak PATH, because clang in $PATH on
Travis focal instances is Clang 7 which is too old (we want Clang 10).
* Travis lacks the array of versions of openssl and gnutls that we normally
use for testing, so we need to exclude some tests (or build our
own multiple versions of openssl and gnutls).
The SSL test exclusions are ad hoc and based on what currently works.

Restore compatibiltiy testing against OpenSSL for
(D)TLS versions smaller that 1.2.
. Fix the check for support in OpenSSL for these versions
. For test cases for (D)TLS version smaller than 1.2,
restore the configuration of OpenSSL client/server

OpenSSL may be configured to support features such as cipher suites or
protocol versions that are disabled by default. Enable them all: we're
testing, we don't care about enabling insecure stuff. This is not needed
with the builds of OpenSSL that we're currently using on the Jenkins CI, but
it's needed with more recent versions such as typically found on developer
machines, and with future CI additions.
The syntax to do that was only introduced in OpenSSL 1.1.0; fortunately we
don't need to do anything special with earlier versions.
With OpenSSL 1.1.1f on Ubuntu 20.04, this is needed to enable TLS 1.0, TLS
1.1 and DTLS 1.0. This also allows SHA-1 in certificates, which is still
needed for a few test cases in ssl-opt.sh. Curiously, this is also needed
for the cipher suite TLS-DHE-PSK-WITH-ARIA-128-GCM-SHA256 (and no other,
including other DHE-PSK or ARIA cipher suites).

psa_cipher_encrypt() and psa_cipher_decrypt() sometimes add a zero offset to
a null pointer when the cipher does not use an IV. This is undefined
behavior, although it works as naively expected on most platforms. This
can cause a crash with modern Clang+ASan (depending on compiler optimizations).

The table size was set before the configured window size bound was

The window size starts giving diminishing returns around 6 on most
platforms and highly unlikely to be more than 31 in practical use cases.
Still, compilers and static analysers might complain about this and
better to be pedantic.

With small exponents (for example, when doing RSA-1024 with CRT, each
prime is 512 bits and we'll use wsize = 5 which may be smaller that the
maximum - or even worse when doing public RSA operations which typically
have a 16-bit exponent so we'll use wsize = 1) the usage of W will have
pre-computed values, then empty space, then the accumulator at the very
end.
Move X next to the precomputed values to make accesses more efficient
and intuitive.
