authfs: support resizing file There are three major changes: 1. Add resize() to MerkleLeaves as the simple hash container. 2. Handle resize for a writable file. The special case is that the hash of the new last chunk can change, and the only way to calculate is to read the original data back. 3. Handle the size change in FUSE.
