reducing debugging messages from arima/hdama/auto.c

[ron minnich]

I hope nobody minds, but since I'm the one who wired these as high, I 
don't think they will. I want to reduce the debug spew from auto.c to get 
some timings. I plan to remove my overrides in auto.c so that it goes back 
to using the level set in Config.lb for debug messages.

thanks
