Combine r.water.outlet easting=, northing= into coordinates= (G_OPT_M_COORDS) for mouse interactivity in g.gui.

[hcho]

I suggest to change the easting and northing parameters in r.water.outlet to the standard G_OPT_M_COORDS parameter (coordinates=). This change will allow the user to click in the monitor to delineate water basins.

Done in r57762. There are three open issues

(1) example noted in the manual gives strange result

r.report basin_A30 u=c -n -h --q

(2) not sure about right fix of remaining compilator warning

In file included from basin.h:3:0,
                 from main.c:31:

(3) MIN macro could be probably used from libgis
