Add experimental unit test harness written in C.
Having the test harness in C will allow us to remove duplicated Perl code and test on systems where Perl support is not present.
Custom harnesses and shims are currently not implemented, which means only the following tests in the common module will run: error, stack-trace, type-convert, assert-on, mem-context, time, encode, type-object, type-string, type-list, type-buffer, type-variant, reg-exp, log.
The experimental test harness is being committed with partial functionality so it can be used in Windows development. The remaining features will follow as needed.
