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. --HG-- rename : tests/quick/50.memtest/test.py => tests/quick/60.rubytest/test.py
