+ripd: Fix two bugs after received SIGHUP signal
+
+There are two problems for ripd implementation after received
+SIGHUP signal:
+1). ripd didn't clean up ifp->connected list before reload
+    configuration file.
+2). ripd reset ri->split_horizon flag to RIP_NO_SPLIT_HORIZON
+    which lead to the unnecessary route to be advertised.
