change fprintf to G_debug in do_proj.c

[quinn]

If you use r.proj to project between coordinate systems that don't share all points, you get many errors to STDERR, for each projection failure. I'm not sure that's necessarily an error, and I suggest the notice be sent to G_debug.

note that in newer SVN fprintf(stderr, has been replaced by G_warning(), but that will still be displayed multiple times and there is no way to turn it off. Also, I think that G_debug(5, will make it too hidden.

Can you give an example of what you mean by "project between coordinate systems that don't share all points"?

Bug seems to be fixed, no answer within 4 years. Taking liberty to close it.
