dirstate-tree: Serialize to disk

The existing `pack_dirstate` function relies on implementation details
of `DirstateMap`, so extract some parts of it as separate functions
for us in the tree-based `DirstateMap`.

The `bytes-cast` crate is updated to a version that has an `as_bytes` method,
not just `from_bytes`:
https://docs.rs/bytes-cast/0.2.0/bytes_cast/trait.BytesCast.html#method.as_bytes

Drive-by refactor `clear_ambiguous_times` which does part of the same thing.
