* For every request to userland we also send the team/thread/user/group ID of

the current thread, now. Implemented by introducing a new base class
  KernelRequest which has respective attributes.
* Server: RequestThreadContext does now also save the request that is being
  processed. Furthermore some space has been reserved for file system specific
  data, which can be initialized by the new
  FileSystem::InitRequestThreadContext().
* FUSE library: Implemented fuse_get_context() using the new
  RequestThreadContext feature.
