Mark Olesen 06b3e9bd0b ENH: update/refine UPstream request handling ...

- activeRequest() checks if given request is still active/pending

- finishedRequest() will now always call MPI_Test when running in
  parallel instead of using a fast-path for skipping a null request.
  This allows MPI a chance to progress operations even if that
  particular request is not active.

- sameProcs() is a convenience wrapper for the following:
  * check if indices resolve to the same underlying procs
  * check the communicator procs against a list of procs
  * to compare two lists of procs.

  For example, check if the communicator corresponds to a
  host-local communication:

     if (UPstream::sameProcs(UPstream::commLocalNode(), myComm)) ...

STYLE: UPstream::Request gets an 'active()' method

- more MPI idiomatic than 'good'
