Implement searching for an inode by name ( #1 )
...
`Synced<Ext2>` now provides the method `find_inode`, which searches for
an inode by absolute path.
New errors that can occur during searching were added.
This commit concludes feature #1 , `fopen`.

Remove old non-thread-safe ext2 implementation
...
Old implementation is now considered legacy. Thread-safety is now
enforced for any non-trivial operations. All trivial operations are
available on the regular `Ext2` struct found in `fs` module.
`Synced<Ext2>` is now the only way to go.

Add Thread-safe version of the ext2 implementation
...
The `Synced<T>` struct is a wrapper over the `Ext2` struct. It
guarantees thread safety through an `Arc` and a spinlock
(`spin::Mutex`).
The `fs::sync` mod provides Thread-safe versions of structs found in `fs`.

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

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 )
