RFR(M): pass outputStream to more opto debug routines

[Vladimir Kozlov]

Thank you, Goetz, for doing this.

Changes are good. One thing I want to ask you is a small codding style 
cleanup. We are converting all cases of "if( a )" to "if (a)" in a 
methods we touch. And I see you have cases like that.

Thanks,
Vladimir
