* Added a mutex to IORequest. It doesn't look like we can get around

using a lock and I'm not very much in favor of a global one.
* Added "finished" callback to IORequest.
* IOOperation::Finish() no longer invokes its parent request's
  ChunkFinished(). The finisher does this instead. ChunkFinished()
  can optionally remove the chunk from the parent.
* Added IORequest::Wait() which waits for the completion of the request.
* Introduced IORequestChunk::ResetStatus() to make setting the status to
  "pending" somewhat more explicit.
* Implemented the missing IOScheduler::SetCallback() methods.
* The NotifyAll() calls on the IOScheduler's condition variables were
  missing, so it just waited forever.
* Added some more debug output.
