Made the following changes from the version I got from Eric: * made BppForSpace() in DriverInterface.h inline to remove some warnings * renamed driver source files to lower case. * removed Be Inc. copyright from kernel driver as I couldn't see anything coming from Be Inc. there - correct me if I was wrong, Eric. * Minor other changes like added missing header guards. * The README provided in the main directory is only included in the accelerant directory. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19793 a95241bf-73f2-0310-859d-f6bbb57e9c96
