 RST lib in quad_divide_data() calls exit with argument 0.

 First - how a failure can be 0 (success)?

 Second - #1598 This looks like one of those places, where G_fatal_error()
 is more appropriate.

 Third - this exit() prevents interpolation when data points are arranged
 in a stripe (filling a hole between two map sheets). Is it really
 necessary to EXIT here instead of just printing a warning?
