Rewrite dlopening stuff in hacky way (due ctypes.util totally brokennes: it attempt to use /sbin/ldconfig, gcc from PATH and other tricks to detect sonames, I replaced it with simple table lookup) Also I add patch to bypass another rounding regression in tests (this patch submitted upstream as well)
