Created an IndexValueStore class which can store any object and return
an integer index to its hash map.
Linear data is now stored in ve.dm.LinearData instances. Two subclasses
for element and meta data contain methods specific to those data types
(ElementLinearData and MetaLinearData).
The static methods in ve.dm.Document that inspected data at a given
offset are now instance methods of ve.dm.ElementLinearData.
AnnotationSets (which are no longer OrderedHashSets) have been moved
to /dm and also have to be instantiated with a pointer the store.

These events occur when an item is inserted or removed by onTransact(),
so both for insertions/removals done through the MetaList mutators and
insertions/removals done by any other means.
We have to gather these events and batch them up because we have to allow
offset translation and index recomputation to occur first (otherwise
calling .getOffset() and .getIndex() on inserted items doesn't work).

Add .insertMeta() and .removeMeta() methods to insert and remove
metadata through the meta list. For convenience, there is also a
.remove() method in MetaItem that wraps around removeMeta().
Also rename insertItem() and removeItem() to addInsertedItem() and
deleteRemovedItem() to avoid confusion, and make the MetaList
constructor take a dm.Surface rather than a document so we can call
change().

A MetaList is a collection of MetaItems representing all of the
metadata in a ve.dm.Document, and it updates itself live as the
underlying document changes.
Currently this interface is read-only, I'll add mutators next.
