This removes the int_link_buffers param from SimpleNetwork. Internal link buffers are now created as children of SimpleIntLink objects. This results in a cleaner configuration and simplifies some code in SimpleNetwork.cc. setup_buffers is also split between Switch.setup_buffers and SimpleIntLink.setup_buffers for clarity.
