Refactor 3D renderer to use multithreading

This try uses full 3D renderers working on the same ZBuffer
target, but are capable to render one stripe per thread.
This is rougher in granularity and uses multiple cores better
than the first try (see gerrit 24393) which was too fine-granular
being based on scanline render parallelization.
SecUred some more classes based on SdrPrimitive3D for multi-
theaded usage (places where local buffered stuff is done)
