* BFS now always writes back the whole block when it writes the super block.

* Therefore, I've added an I/O control that let's it update the boot block
  part of this block, so that makebootable can use it on a mounted volume
  (this will probably be moved into a disk system API later).
* Added user_memcpy() to the fs_shell.
* Minor cleanup.
