[OpenWrt-Devel] [PATCH] [RFC] libubus.h: add ubus_auto_shutdown()

[Ben Kelly]

From: Ben Kelly <ben at benjii.net>

Add ubus_auto_shutdown function, which ensures any pending uloop_timer is cancelled before calling ubus_shutdown on the context. 

This avoids a condition where ubus_shutdown() is called during ubus_auto_connect attempting a reconnection.
