mesh: update libs

1. add APIs to set/get announce interval values.
2. add API to enable/disable the min rate to 6Mbps for data packages.
3. add APIs to set/get RSSI threshold values.
4. fix ap_loss.

+# Mesh Manual Networking Example
+
+ESP-MESH provides the function of self-organized networking, but if users disable this function on one node, users must designate a parent for this node.
+
+
+This example demonstrates how to scan a list of parent candidates, choose an appropriate parent and set as the parent of this node.
+
+If no parent is found through this scan, enable the self-organized function to let the ESP-MESH handle it by itself.
+
+Run `make menuconfig` to configure the mesh network channel, router SSID, router password and mesh softAP settings.
+
+When the mesh network is established and if you happen to run this example on ESP-WROVER-KIT boards, the RGB light indicator will show you on which layer devices are. The pink reprents root; the yellow reprents layer 2; the red reprents layer 3; the blue reprents layer 4; the green reprents layer 5; the white reprents layer greater than 5.
