The script was parsing the output from `make lcov` to extract numbers and
calculate percentages. But everything including the percentages is already
present in the output of `make lcov`, just with a slightly different
presentation. So replace all this by a simple extraction of the relevant
lines from the output of `make lcov`.
This is more robust than the previous code, which relied on `tail -n4` to
extract relevant lines, which broke when `make lcov` started to emit one
extra line at the end.

In the basic/XXX=core test cases, use odd upper bounds, because the mod
version of random() only supports odd upper bounds (the upper bound is a
modulus and the mod modules only support odd moduli).

Move bignum-related helper functions to their own files under tests/include

bignum_helpers.h include library/bignum*.h, but we want to be able to
include <test/helpers.h> without having the library directory on the include
path (we do this in some programs under programs/ intended for testing).

mpi_core_random_basic and mpi_random_values must generate the same random
sequences in order to get the expected test coverage (where we know we'll
hit certain numbers of retries). Facilitate this by defining the RNG seed
only once.
Fix the seed to explicitly list all 16 words of the key. This isn't strictly
required (missing initializer fields get the value zero), but it's clearer.

The previous commit declared that some tests cases in ssl-opt.sh depend
on USE_PSA being disabled, which is the right thing to do.
We had a check that forbade that - it was mainly meant to prevent
accidental re-introduction of such dependencies after we cleaned up a
number of cases where it was not warranted, but already at the time that
was controversial [1]. Now it's preventing us from doing the right
thing, so let's just remove it.

This fixes the two failures in test_suite_x509parse when both
ECP_RESTARTABLE and USE_PSA_CRYPTO are enabled.
The failure happened because the operation is dispatched to PSA when
restart is disabled (max_ops == 0).
Previously it was correct for this test function not to initialize PSA,
because it depends on ECP_RESTARTABLE which used to conflict with
USE_PSA_CRYPTO, but that's no longer the case.

It might not be obvious that this option goes beyond adding new
functions, but also automagically modifies the behaviour of TLS
in some circumstances. Moreover, the exact modifications and
circumstances were not documented anywhere outside the ChangeLog.
Fix that.
While at it, adjust the test that checks no restartable behaviour with
other key exchanges, to use a key exchange that allows cert-based client
authentication so that we can check that this is not restartable either.
We don't have any automated test checking that the server is never
affected. That would require adding an ec_max_ops command-line option to
ssl_server2 that never has any effect, just to check that it indeed
doesn't. I'm not sure that's worth it. I tested manually and could
confirm that the server never has restartable behaviour, even for the
parts that are shared between client and server such as cert chain
verification.
Note (from re-reading the code): all restartable behaviour is controlled
by the flag ssl->handshake->ecrs_enabled which is only client-side with
the ECDHE-ECDSA key exchange (TLS 1.2).

Test some cases where mbedtls_mpi_core_random() or mbedtls_mpi_random()
should return MBEDTLS_ERR_MPI_NOT_ACCEPTABLE. These test cases use a very
small range that makes the NOT_ACCEPTABLE case likely. The test code uses a
deterministic RNG whose implementation is in the test framework, so we know
that the tests will pass reproducibly unless the implementation the test
framework changes.

The test function mpi_random_many() is the main function for testing the
get-random-in-range function. It validates that the random generator's
output is within the desired range, and performs some basic statistical
checks including checking that small ranges are covered exhaustively.
Switch this function from testing mbedtls_mpi_random() to testing
mbedtls_mpi_core_random(). This does not reduce the test coverage of
mbedtls_mpi_random() because the same properties are now validated
indirectly via mpi_random_values() which checks that mbedtls_mpi_random()
and mbedtls_mpi_core_random() produce identical values for identical inputs.
As of this commit, mpi_random_many() still uses some legacy mpi functions
internally because the corresponding functions don't exist yet in core.

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.

defaults to -O2 and not using any -O in the replacement. (CMake already has
