578613322a Add test cases with a question mark 
The test framework used to treat them specially (but no longer does). Add
these test cases as non-regression for how the test framework allows "?"
and especially "??" (which I think in the very distant path needed special
handling because the test data was embedded in a .c file, and thus ?? could
be interpreted as the prefix of a trigraph).

872948cc72 Support larger integer test arguments: C part 
Change the type of signed integer arguments from int32_t to intmax_t.
This allows the C code to work with test function arguments with a range
larger than int32_t. A subsequent commit will change the .datax generator
to support larger types.

4ea4ad082b parse_function_arguments: stricter type parsing 
Use normalization the equality comparisons instead of loose regular
expressions to determine the type of an argument of a test function.

Now declarations are parsed in a stricter way: there can't be ignored junk
at the beginning or at the end. For example, `long long unsigned int x`
was accepted as a test function argument (but not `long long unsigned x`),
although this was misleading since the value was truncated to the range of
int. Now only recognized types are accepted.

The new code is slightly looser in that it accepts `char const*` as well as
`const char*`.

b3c2eaf00f Support different types in the parameter store 
The test framework stores size_t and int32_t values in the parameter store
by converting them all to int. This is ok in practice, since we assume int
covers int32_t and we don't have test data larger than 2GB. But it's
confusing and error-prone. So make the parameter store a union, which allows
size_t values not to be potentially truncated and makes the code a little
clearer.

5226eb5cd3 Simplify parsing of integers in .datax files 
In the .datax parser, since we're calling strtol() anyway, rely on it for
verification. This makes the .datax parser very slightly more
liberal (leading spaces and '+' are now accepted), and changes the
interpretation of numbers with leading zeros to octal.

Before, an argument like :0123: was parsed as decimal, but an argument like
:0123+1: was parsed as a C expression and hence the leading zero marked an
octal representation. Now, a leading zero is always interpreted according to
C syntax, namely indicating octal. There are no nonzero integer constants
with a leading zero in a .data file, so this does not affect existing test
cases.

In the .datax generator, allow negative arguments to be 'int' (before, they
were systematically treated as 'exp' even though they didn't need to be).

In the .datax parser, validate the range of integer constants. They have to
fit in int32_t. In the .datax generator, use 'exp' instead of 'int' for
integer constants that are out of range.

1a24895bfd Simplify string escapes 
Treat backslash as a universal escape character: "\n" is a newline,
backslash escapes any non-alphanumeric character.

This affects some test cases that had "\," standing for backslash-comma.
With the new uniform treatment of backslashes, this needs to be "\\,".

187932639b Remove stdint.h substitute for older MSVC
