-/**
- * 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
- *     'changes_to_return': [                         // 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>',
- *     'ongoing_syncs': {
- *         '<source_replica_uid>': {
- *             'sync_id': '<sync_id>',
- *             'seen_ids': [['<doc_id>', <at_gen>[, ...],
- *             'changes_to_return': {
- *                  'gen': <gen>,
- *                  'trans_id': '<trans_id>',
- *                  'changes_to_return': [
- *                          ['<doc_id>', <gen>, '<trans_id>'],
- *                          ...,
- *                  ],
- *             },
- *         },
- *         ... // info about other source replicas here
- *     }
- * }
