Since the ProcFS doesn't hold many global objects within it, the need for a fully-structured design of backing components and a registry like with the SysFS is no longer true. To acommodate this, let's remove all backing store and components of the ProcFS, so now it resembles what we had in the early days of ProcFS in the project - a mostly-static filesystem, with very small amount of kmalloc allocations needed. We still use the inode index mechanism to understand the role of each inode, but this is done in a much "static"ier way than before.
