Subject: [PATCH] land b_bug3262 onto b1_4. b=3262, r=Robert for client obd
 device, we could freely add/delete connections to possible targets. if one
 connection out of work (timeout, etc) we'll try the backup connections round
 robinly, so client recovery could be no upcalls. but it also compatible to
 original upcalls for special need.
