服務商代子商戶發起添加分賬接收方請求

在統一下單API、付款碼支付API、委託扣款API中上傳新增參數profit_sharing，請求支付
支付完成後，調用請求分賬接口，完成分賬

注意事項

分賬接口分爲單次分賬和多次分賬
當用戶需要退款時，單次分賬調用接口的步驟是：分賬回退->申請退款
當用戶需要退款時，多次分賬調用接口的步驟是：分賬完結->分賬回退->申請退款
商戶系統內部的分賬單號，在商戶系統內部唯一（單次分賬、多次分賬、完結分賬應使用不同的商戶分賬單號），同一分賬單號多次請求等同一次。
Ilog是一個日誌類
ProfitSharingSign.class.php是用來生成簽名的，跟微信支付、微信退款生成簽名類是一樣的
ProfitSharingCurl.class.php是一個發送http請求的類
pdo_*的方法是微擎框架自帶的數據庫操作
