This patch adds the function strscpy_pad() named after consensus was reached on the v1 email thread (linked to above). Thanks to Kees for the extreme test case coverage. test_basic() is probably redundant but is left in for the benefit of any poor sucker who has to debug a regression using test_fully(). The test module is _not_ tied into kselftest. As discussed on v1, there are some issues with tools/testing/selftest/lib/ at the moment. I intend on working on those issues as suggested but it does not seem totally relevant to this patch so instead of slowing this one down with my poor knowledge of how kselftest works it seems better to do this separately. thanks for looking at this, Tobin.
