When testing under Valgrind for constant flow, skip test suites that don't
have any constant-flow annotations, since the testing wouldn't do anything
more that testing with ordinary Valgrind (component_test_valgrind and
component_test_valgrind_psa). This is a significant time saving since
testing with Valgrind is very slow.

This is the first step in arranging that functions from constant_time.c are
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.

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.

Require equality for the number of limbs in the modulus and the residue.
This makes these functions consistent with residue_setup().

Test macros have goto instructions to the end where everything is freed.
We need to call init before that happens to make calling free functions
safe.

The external representation before included more than just endianness
(like reading in Mongtomery curve scalars or converting hashes to
numbers in a standard compliant way).
These are higher level concepts and are out of scope for Bignum and for
the modulus structure.

In theory we could allow residues to have more allocated limbs than the
modulus, but we might or might not need it in the end.
Go for the simpler option for now and we can extend it later if we
really need it.

We want to make sure that the value has at least as many limbs allocated
as the modulus as we need this to be able to do any operations in
constant time.
An invariant of the API is that the residue values are canonical, make
sure that the residue is compared to the entire modulus.

CID is now enabled in the default config (as well as full), so it's
already tested in numerous all.sh components, not need to add one for
that.
We need a component for the legacy/compat option though as it's never
enabled in existing components. So, keep that one, but adjust the name
and fix a typo in a message.

We don't need to have two copies of the test with one of them depending
on legacy/compat CID: we can have just one copy, but make sure we run
ssl-opt.sh both in a build with standard CID and in a build with
legacy/compat - that's the job of all.sh (see next commit).

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 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 test cases aim to mirror the legacy function, but needed the some
cases to be removed because:
- Null representation is not valid in core
- There are no negative numbers in core
- Bignum core doesn't do parameter checking and there are no promises for
even N
The _size variant of the test has been removed as bignum core doesn't do
parameter checking and there is no promises for inputs that are larger
than MBEDTLS_MPI_MAX_SIZE.

- external errors are now checked in the specified point. If the
same error happens in another line, then this is not valid and
the test fails
- fixed some inconsistency in which injected error codes were not
taken from the data file. Now all the expected error code are
read from the data file
- added a couple of defines to shrink the code

As for ecjpake_setup(), now the test function can handle:
- "external" errors, through parameters set by the data file
- "internal" ones, through enums which inject ad-hoc failures
Similarly also ecjpake_rounds() can handle both type of errors,
but right now there's no erroneous case in the associated ".data"
file.
In both cases, after an error the current test is terminated.
