Add ut_get_str(), ut_get_int(), and ut_get_bool() functions with
corresponding ut_str(), ut_int(), and ut_bool() macros for accessing
test arguments with type checking.
These functions check that the argument index is within bounds and the
type matches what was requested.
The first failure for a test is reported via ut_failf() which should
make it fairly easy to debug the test.
