(trunk) #2548 "T's request queue can send out too many duplicate requests" -- (1) fix r9465 implementation bug that caused some peers to get starved of requests if they rejected a request or choked, then unchoked us. (2) increase a block request's TTL by 15 seconds to reduce cancel/req cycles between two or more blocks (3) add a debug mode to the GTK+ client's peer tab to watch the pending requests counts both up & down
