EXT2 3 Read Only Support

Everything is untested under ext2 and ext3. At least ext4fuse is able to mount an empty filesystem. There is a lack of support for double and triple indirect block addressing, which rules out big files (>4MB on 4K block size). Luckily, native ext4 filesystems don’t use non-extent addressing (the exception seems to be lost+found, created at mke2fs time)

However, implementing the lacking support shouldn’t be much of a trouble, just hooking in inode_get_data_pblock should do
