/*
 * Internal function: udf_aerospike_setbin
 *
 * Parameters:
 * 		r 		-- udf_record to be manipulated
 * 		bname 	-- name of the bin to be deleted
 *		val		-- value to be updated with
 *
 * Return value:
 * 		0  on success
 * 	   -1  on failure
 *
 * Description:
 * 		The function sets the bin with the name
 * 		passed in as parameter to the value, passed as the third parameter.
 * 		Before updating the bin, it is checked if the value can fit in the storage
 *
 * 		Synchronization : object lock acquired by the transaction thread executing UDF.
 * 		Partition reservation takes place just before the transaction starts executing
 * 		( look for as_partition_reserve_udf in thr_tsvc.c )
 *
 * 		Callers:
 * 		udf_aerospike__apply_update_atomic
 * 		In this function, if it fails at the time of update, the record is set
 * 		to rollback all the updates till this point. The case where it fails in
 * 		rollback is not handled.
 *
 * 		Side Notes:
 * 		i.	write_to_device will be set to true on a successful bin update.
 * 		If all the updates from udf_aerospike__apply_update_atomic (including this) are
 * 		successful, the record will be written to disk and reopened so that the rest of
 * 		sets of updates can be applied.
 *
 * 		ii.	If put in sindex fails, we do not handle it.
 *
 * 		TODO make sure anything goes into setbin only if the bin value is
 * 		          changed
