Information about what kernel to load and how to load it was built into the System object and its subclasses. That overloaded the System object and made it responsible for too many things, and also was somewhat awkward when working with SE mode which doesn't have a kernel. This change extracts the kernel and information related to it from the System object and puts into into a OsKernel or Workload object. Currently the idea of a "Workload" to run and a kernel are a bit muddled, an unfortunate carry-over from the original code. It's also an implication of trying not to make too sweeping of a change, and to minimize the number of times configs need to change, ie avoiding creating a "kernel" parameter which would shortly thereafter be renamed to "workload". In future changes, the ideas of a kernel and a workload will be disentangled, and workloads will be expanded to include emulated operating systems which shephard and contain Process-es for syscall emulation. This change was originally split into pieces to make reviewing it easier.
