Log Message:
Update the file system snapshot driver:
- Document the kernel thread.
- Rename some functions and variables.
- Return EROFS where appropriate.
- Use shifts instead of 64-bit divide.
- Use a simple_lock to make it MP-safe.
- Add M_CANFAIL to malloc to avoid panic on large cluster size.
- Allow sparse file for backing store and use VOP_BALLOC() to allocate
  space. Default size of backing store is the size of the file system.
