Clean up the alloc_io_space() function by moving most of it to the actual resource_ops. This allows for a bit less re-directions. Future cleanups will follow, and will make up for the code duplication currently present between rsrc_iodyn and rsrc_nonstatic (which are hardly ever built at the same time anyway, therefore no increase in built size).
