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.

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.

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 "\\,".

No intended behavior change. This commit is mainly to satisfy pylint, which
complains that gen_from_test_data now has too many variables. But it's a
good thing anyway to make the function a little more readable.

We're using the non-standard function strcasecmp() just so that the case
of digits beyond 9 can be different in the library and in the test data.
Use matching case in the test data, and use a standard function for the
comparison.

This patch introduces a `MBEDTLS_STATIC_TESTABLE` helper
method which exposes `ecp_mod_p256k1()` to the test-framework

This patch introduces basic unit-testing for the `ecp_mod_p224k1()`.
The method is exposed through the ecp_invasive interface, and
the standard testing data is being provided by the python framework.
