bookmark: track bookmark changes at the transaction level
The transaction has now a 'bookmarks' dictionary in tr.changes. The structure
of the dictionary is {BOOKMARK_NAME: (OLD_NODE, NEW_NODE)}. If a bookmark is
deleted NEW_NODE will be None. If a bookmark is created OLD_NODE will be None.
If the bookmark is updated multiple time, the initial value is preserved.
