`Default` where they can.

Improve filter_changes for sync (#126)
* Improve filter_changes for sync

This helps to avoid traversing the entire graph when we get a successive
change that we know can't be a predecessor of the heads.

Also filter_changes shouldn't be globally public.

Add event handler logic (#116)
* Add event handlers

Remove partialeq from Backend since I'm not sure of its relevance or
correctness anyway and complicates things with the event handlers.

* Add docs and use id

* Remove partialeq

* Add docs for enum variants

* Check index on remove_handler

* Pass functions through rather than making field pub

8254ba6231 Change states to use indices into history
This moves to storing the changes only in history and everything else
pointing to that. This reduces duplication and so memory usage,
especially when we may have large changes or documents.

Remove automerge bench harness (#106)
This removes the default wrapper which throws errors with some cli
arguments, e.g. --save-baseline which is nice for being able to compare
versions!

3a8baf7b0a Filter sent hashes down to only what they haven't seen
This means we no longer need to store an unbounded list of hashes while
syncing. This is possible as we know their heads and all changes we send
should be known to us, thus we can look in our history to see whether
they are safely applied at the other end.

8d3096b823 Make sent_hashes a set instead of a vec
We don't care about the ordering so we can just store them in a hashset
all of the time, avoiding having to rebuild the hashset each time.

220580506d Performance updates
Where we do lots of contains checks we should use hashsets rather than
linear scan through a Vec.

Also tried to minimise some copying.
