This adds a white-box unit test that verifies that GL_BLEND is disabled when drawing an opaque rectangle, enabled when drawing a transparent rectangle and then disabled again when drawing a transparent rectangle but with a blend string that effectively disables blending. This shares the test utilities and launcher infrastructure we are using for conformance tests so we get consistent reporting and so unit tests will be run against a range of different drivers. This adds a --enable-unit-tests configure option which is enabled by default but if disabled will make all UNIT_TESTS() into static inline functions that we should expect the compiler to discard since they won't be referenced by anything.
