Changes since 1.10: +28 -43 lines 
- change all exch_*_rx.template to call new exch1_rx S/R ;
- update Makefile and .cvsignore
- replace call to exch2_xy_rx S/R with exch2_*3d_rx(Nr=1) (will remove
  exch2_xy_rx later)

19 C *==========================================================*
20 C | SUBROUTINE EXCH_UV_XY_RX
21 C | o Handle exchanges for _RX, 2-dimensional vector arrays.
22 C *==========================================================*
23 C | Vector arrays need to be rotated and interchaged for
24 C | exchange operations on some grids. This driver routine
25 C | branches to support this.
