Update of /u/gcmpack/MITgcm/pkg/mom_common
In directory forge:/tmp/cvs-serv15633

Modified Files:
	mom_u_bottomdrag.F mom_v_bottomdrag.F 
Log Message:
- add one argument (the other velocity component) to S/R MOM_U/V_BOTTOMDRAG;
- add options for alternative discretisation of velocity norm in quadratic
  bottom drag: averaging of grid-cell-center KE to U.point and V.point
  (selectBotDragQuadr=0, original code) can produce noisy patterns; this
  improves when averaging only the other component (e.g. vVel for U bottom
  drag) using wet-point method (selectBotDragQuadr=2) or not (=1).
- add options (bottomVisc_pCell) to account for partial-cell in bottom
  friction (no-slip BC) thus getting the true distance from the bottom;
  off by default since this also reduces model stability (explicit bottom
  friction).
