The current macro collector only tried the minimum and maximum expressible
lengths for PSA_ALG_TRUNCATED_MAC and PSA_ALG_AEAD_WITH_DEFAULT_LENGTH_TAG.
This was good enough for psa_constant_names, but it's weak for exercising
keys, in particular because it doesn't include any valid AEAD tag length.
So cover more lengths.

Support ECB, which has no IV. The code also now supports arbitrary IV
lengths based on the algorithm and key type.

Only allow selected modes with 64-bit block ciphers (i.e. DES).
This removes some storage tests and creates corresponding op_fail tests.

In key read tests, add usage flags that are suitable for the key type and
algorithm. This way, the call to exercise_key() in the test not only checks
that exporting the key is possible, but also that operations on the key are
possible.
This triggers a number of failures in edge cases where the generator
generates combinations that are not valid, which will be fixed in subsequent
commits.

This currently makes all the descriptions unambiguous even when truncated at
66 characters, as the unit test framework does.

The output of generate_psa_tests.py is almost unchanged: the differences are
only spaces after commas (now consistently omitted).

When generating storage format tests, pass usage flags around as a list, and
format them as the last thing.
In Storagekey(), simplify the addition of implicit usage flags: this no
longer requires parsing.
The output is unchanged.

In the generated storage format test cases, cover all supported
algorithms for each key type. This is a step towards exercising
the key with all the algorithms it supports; a subsequent commit
will generate a policy that permits the specified algorithms.

Use the new generic is_public method.
Impact on generated cases: there are new HMAC test cases for SIGN_HASH. It
was a bug that these test cases were previously not generated.

Removing the trimming has significant memory impact. While it is clearly what
we want to do eventually for constant-time'ness, it should be fixed alongside
a strategy to contain the ramifications on memory usage.

It no longer makes sense, either in -e or -f: those ciphersuites have
been removed anyway.

- comments about (3)DES were inconsistent (one saying "keep 3DES" and
the other "exclude it")
- we don't have any DES or 3DES ciphersuite anyway, so no need to
exclude them or comment about it
- while at it, fix comment about ARIA: it's in the default config now

The ciphers were originally separated by the version conditions, and the spacing
was retained in case it was required later. It has been decided it would be better
to have an unbroken list in alphabetically order to quickly locate ciphers when
necessary

As anything below (D)TLS 1.2 is no longer supported, checks for the
minor version will always be true, and have therefore been removed

The variable is a local variable for the i386 bignum assembly only;
introduce it as part of the start/finish macros.
It can be noted that the variable is initialize to 0 within MULADDC_INIT,
so there are no data dependencies across blocks of MULADDC_INIT/CORE/STOP.
