/** stores data in a starsh tree to peristent storage.
This function can be called to save all data in a stash tree to
Net-SNMP's percent storage. Make sure you register a parsing
function with the read_config system to re-incorperate your saved
data into future trees.
@param root the top of the stash to store.
@param tokenname the file token name to save in (passing "snmpd" will
save things into snmpd.conf).
@param dumpfn A function which can dump the data stored at a particular
node into a char buffer.
@param curoid must be a pointer to a OID array of length MAX_OID_LEN.
@param curoid_len must be 0 for the top level call.
