a Stream, and then added GetOutputData & GetErrorData to get the accumulated data. - Added a StreamTee that will tee output to two provided lldb::StreamSP's. - Made the CommandObjectReturn use this so you can Tee the results immediately to the debuggers output file, as well as saving up the results to return when the command is done executing. - HandleCommands now uses this so that if you have a set of commands that continue the target you will see the commands come out as they are processed. - The Driver now uses this to output the command results as you go, which makes the interface more reactive seeming. llvm-svn: 126015
