* The nature of asynchronous I/O is to be asynchronous. So we can't store

an on-stack structure for the request in a hash table when forwarding the
  io() hook. Create a new object (HaikuKernelIORequest) instead and store it
  in a hash table in HaikuKernelFileSystem.
* Some work on the userland side of do_iterative_fd_io().
* Added some missing requests in UserlandFSUtil::is_{kernel,userland}_request().
