Commit of sasl_format_report

[Jay Nelson]

Committed the addition of sasl_report:format_report/3 which generates  
a string in the same format that sasl_report:write_report/3 would  
write to the io device.  Maintains backwards compatibility for  
existing code.

git fetch git://github.com/jaynel/otp.git sasl_format_report


I noticed commented out code in rb_format_supp.erl which calls  
sasl_report:write_report/2 which is a non-existent function.  I left  
the comments there as I was not certain the purpose they serve.
