ruby: reset and dump stats along with reset of the system
This patch adds support to ruby so that the statistics maintained by ruby are reset/dumped when the statistics for the rest of the system are reset/dumped. For resetting the statistics, ruby now provides the resetStats() function that a sim object can provide. As a consequence, the clearStats() function has been removed from RubySystem. For dumping stats, Ruby now adds a callback event to the dumpStatsQueue. The exit callback that ruby used to add earlier is being removed. Created by: Hamid Reza Khaleghzadeh. Improved by: Lluc Alvarez, Nilay Vaish Committed by: Nilay Vaish
