1. ForkProcess: Use duplicate fd_pipes in _send_fd_pipes thread …

   In order to allow callers to manage the lifecycle of fd_pipes
   file descriptors, create duplicates for _send_fd_pipes to
   close when it has finished sending them.
   
   This fixes bug 916601 in a nice way, allowing commit
   3b1234b to be reverted.

3. process.spawn: Use multiprocessing.Process for returnproc …

   Use multiprocessing.Process for returnproc, so that
   fork will stop being used when python makes "spawn"
   the default multiprocessing start method.
   
   Continue to use _start_fork when returnproc is not
   enabled, for backward compatibility. Ultimately,
   it can be removed at the same time as the returnpid
   parameter.
