Szymon Walter 36f13bea2a Reformat 
- `length::Length` was renamed as `size::Size` to better reflect the
 purpose
 - `sector::Size` was renamed as `sector::SectorSize`
 - lifetime names were given meaning (etc. `'vol`, `'inode`)
 - `Volume` and `Length` were changed to be generic over `S:
 SectorSize`, instead of `Idx` and now use `Address<S>` as the only
 addressing (indexing) type

Szymon Walter bebfa33564 Implement a directory entry iterator for inode 
Calling `directory()` on an `Inode` returns an `Iterator` over entries in
a directory at that `Inode`, it it's a directory, or `None` otherwise.

An example of recursively walking the directory tree is included in test
`walkdir`.

This takes us a step closer to `fopen` (#2)

Szymon Walter d5423d7199 Change sector::Address implementation to use u32

Volume.
