Christopher Haster 11d6d1251e Dropped namespacing of test cases
The main benefit is small test ids everywhere, though this is with the
downside of needing longer names to properly prefix and avoid
collisions. But this fits into the rest of the scripts with globally
unique names a bit better. This is a C project after all.

The other small benefit is test generators may have an easier time since
per-case symbols can expect to be unique.
