mem: Rename Bus to XBar to better reflect its behaviour
This patch changes the name of the Bus classes to XBar to better reflect the actual timing behaviour. The actual instances in the config scripts are not renamed, and remain as e.g. iobus or membus. As part of this renaming, the code has also been clean up slightly, making use of range-based for loops and tidying up some comments. The only changes outside the bus/crossbar code is due to the delay variables in the packet. --HG-- rename : src/mem/Bus.py => src/mem/XBar.py rename : src/mem/coherent_bus.cc => src/mem/coherent_xbar.cc rename : src/mem/coherent_bus.hh => src/mem/coherent_xbar.hh rename : src/mem/noncoherent_bus.cc => src/mem/noncoherent_xbar.cc rename : src/mem/noncoherent_bus.hh => src/mem/noncoherent_xbar.hh rename : src/mem/bus.cc => src/mem/xbar.cc rename : src/mem/bus.hh => src/mem/xbar.hh
