Axel Dörfler f774bf16ea Implemented vm_copy_area(), mainly a support function for fork().
vm_page no longer keeps a pointer to the vm_cache_ref but to the vm_cache.
This cleans the page handling when having to make an area copy-on-write;
regions belong to vm_cache_ref, pages to vm_cache.
Fixed some return types.
