+/**
+ * This update handler stores information about ongoing synchronization
+ * attempts from distinct source replicas.
+ *
+ * Normally, u1db synchronization occurs during one POST request. In order to
+ * split that into many serial POST requests, we store the state of each sync
+ * in the server, using a document with id 'u1db_sync_state'. To identify
+ * each sync attempt, we use a sync_id sent by the client. If we ever receive
+ * a new sync_id, we trash current data for that source replica and start
+ * over.
+ *
+ * We expect the following in the document body:
+ *
+ * {
+ * 'source_replica_uid': '<source_replica_uid>',
+ * 'sync_id': '<sync_id>',
+ * 'seen_ids': [['<doc_id>', <at_gen>], ...], // optional

+ * 'gen': <gen>,
+ * 'trans_id': '<trans_id>',
+ * 'changes_to_return': [[<doc_id>', <gen>, '<trans_id>'], ...]
+ * ],
+ * }
+ *
+ * The format of the final document stored on server is:
+ *
+ * {
+ * '_id': '<str>',
+ * '_rev' '<str>',
