GL_ARB_enhanced_layouts, part 6: Numerical side of uniform offset and align semantics. Included

- moving offset calculations for std140/std430 from reflection to linkValidate.cpp
 - applying the offset/align rules on top of std140/std430
 - removing caching the structure's number of components (and correcting that this is components, not size)
