COSOperator::getSystemMemory now returns some value on OSX. Also it's kb not bytes.

Browse Source 
Before the value was checked, but not put into the return variables.
Header update to show that information in kb not bytes (on all systems, was just documented wrong)
Some cleanup of code.

--------------------------
Changes in 1.9 (not yet released)
- COSOperator::getSystemMemory now returns some value on OSX (thought same for total and available).
Thanks @sfan5 for patch https://irrlicht.sourceforge.io/forum/viewtopic.php?f=2&t=52819 and https://github.com/minetest/irrlicht/commit/e469c54f76f6d24f92389b4e8a27b9cce7152888
- Fix CVertexBuffer::setType switching types for non-empty arrays. Before we had some bad casts which could result in random initializing of some vertex data.
- IVertexBuffer interface changes: pointer() now returns void*. Adding a const version of getData(). Some set functions have now overload for all vertex types.
- S3DVertex now always initializes color to 0xffffff. That was previously the only uninitialized variable in there. Also both derived classes have now a constructor taking a const S3DVertex&.
