m5: Regression Tester Update

This patch includes the necessary regression updates to test the new ruby
configuration system.  The patch includes support for multiple ruby protocols
and adds the ruby random tester.  The patch removes atomic mode test for
ruby since ruby does not support atomic mode acceses.  These tests can be
added back in when ruby supports atomic mode for real.
