Certstore system tests fail if certificates are not installed. about botan

[reneme]

The dependence on "certain" well-known root certificates in the test has always been somewhat an Achilles heel, unfortunately.

I'm in favor of (3), in a sense that we "somehow" flag the tests that assume the trust in certain root certs as "may-fail" in the test setup. AFAIK Botan's test system doesn't have this functionality, yet.

I'm envisioning something like:

auto test_that_assumes_existence_of_some_root() {
   Test::Result result("Test OS certstor, MAY_FAIL);
   /* ... test all the things ... */
   return result
}

... if the test fails, it should print a warning by default but not set the return code of ./botan-test.exe. Except the tests were invoked with ./botan-test.exe --strict (or similar).
