* Lookup transfers. Note that filtering by @a verified status is done
* outside of SQL, as we already have 8 prepared statements and adding
* a filter on verified would further double the number of statements for
* a likely rather ineffective filter. So we apply that filter in

* @param after timestamp for the last transfer we care about
* @param limit number of entries to return, negative for descending in execution time,
* positive for ascending in execution time
* @param offset transfer_serial number of the transfer we want to offset from
* @param verified filter transfers by verification status
* @param cb function to call with detailed transfer data
* @param cb_cls closure for @a cb
