Motivation is to: - use on simpler and light test framework, - eliminate dependency on libraries like Boost.MPL, - achieve faster compilation times for CI builds (20% seems feasible) - have test programs easy to run and debug - avoid macros Remove outdated FIXME-s for bugs that have been already fixed. Fix off-by-one bug in test/core/test_fixture.hpp generators. Minor corrections and tidying up. Add missing test assertions to numeric extension tests. Fixes #458
