Instead of capturing the output of diff and printing it, let diff do its
own outputting and se the return code to decide what to do.
This also means that the conversion of stdout to UTF-8 is not necessary,
as the reason it was needed was for printing diffs of files with UTF-8
characters in them.

Explain what's going on in BignumModRawConvertRep.test_case_for_values.
Simplify the logic and the interdependencies related to limb sizes:
* Montgomery is the special case, so base the decisions on it.
* As soon as we've encountered one limb size, no matter what it is,
give up.
No behavior change, other than changing the numbering of test cases (which
previously included more skipped test cases).

Ideally the result of the generator would conform to the code style, but
this would be difficult, especially with respect to the placement of line
breaks in long logical lines. So, to avoid surprises when checking the style
of generated files (which happens in releases and in long-time support
branches), systematically skip generated files.

The goal of this commit is to add some constants that can be used to
define datasets and add test data in a more readable and reusable
manner.
All platforms using ECC need to support calculations with at least 192
bits, therefore constants for this length are added. We are not using a
curve prime as those will be tested elsewhere and it is better not to
play favourites.
All platforms using RSA or FFDH need to support calculations with at
least 1024 bits, therefore numbers of this size are added too.
A safe prime is added for both sizes as it makes all elements generators
(except 0 and 1 of course), which in turn makes some tests more
effective.

Sometimes we don't want all possible combinations of the input data and

automatically.

Having int_ variants as an attribute has the advantage of the input
being validated when the object is instantiated. In theory otherwise if
a particular int_ attribute is not accessed, then the invalid argument
is passed to the tests as it is. (This would in all likelihood detected
by the actual test cases, still, it is more robust like this.)

Before arg_ attributes were the arguments as they were defined in the

Although negative zero is officially unsupported, we've had bugs related to
it in the past. So do test functions with a negative zero input.
There will likely be cases where we don't want to accept negative zero as if
it was valid, because it's too hard to handle. We'll add exceptions on a
case by case basis.
For the functions that are currently tested by the generated tests, the new
test cases pass.
