Keiichi Watanabe a00e6ab356 ext2: Use constant for block size (4096 bytes) 
The only supported block size in the ext2 crate is 4K. So, use a
constant value rather than having a function `block_size()`.
Also, we expose this block size constant so the user of this
crate will be able to write a code that relies on the block size.

ext2

This crate provides utilities to create ext2 file system on memory or a file.

examples/mkfs.rs shows how to use this library. This program is our alternative to mkfs.ext2 that create an ext2 file system on a file and useful for debugging this ext2 itself with existing utilities in e2fsprogs such as fsck and dumpe2fs.

$ cargo run --release --example mkfs -- --path disk.img
Create disk.img
$ dumpe2fs disk.img
