* The team and thread kernel structures have been renamed to Team and Thread respectively and moved into the new BKernel namespace. * Several (kernel add-on) sources have been converted from C to C++ since private kernel headers are included that are no longer C compatible. Changes after merging: * Fixed gcc 2 build (warnings mainly in the scary firewire bus manager). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@40196 a95241bf-73f2-0310-859d-f6bbb57e9c96
