RFR(xs): 8220786: Create new switch to redirect error reporting output to stdout or stderr

[Lindenmaier, Goetz]

HI Thomas, 

this change basically looks good.

In the CSR, it has been discussed which flag should take precedence.
Did you think about implementing a constraint for the flag 
issuing a warning if both are set?

Best regards,
  Goetz.
