Catrope 857535b63f Introduce meta-linmod
* ve.dm.Converter still generates metaInline/metaBlock elements as
  before, it's not affected by this change
* ve.dm.Document constructor splits its input into "real" data and
  metadata
** Metadata is stored in this.metadata (the meta-linmod) as a sparse
   array of arrays, with an element for each offset in this.data
** this.data itself does not contain the metadata
** This means the node tree also doesn't contain the metadata
** Which means CE doesn't know about it at all
* All splice operations on the linear model are sent through
  ve.dm.Document.spliceData(), which performs the splice and syncs the
  meta-linmod
** Metadata in the removed range is reaped and added to the metadata for
   the offset immediately following the removal
* ve.dm.Document.getFullData() splices the linmod and meta-linmod back
  into each other; this "full data" is then fed back to ve.dm.Converter
