These patches add the reconnect support in vduse, The steps is map the pages from kernel to userspace, userspace app will sync the reconnection status and vq_info in the pages Also, add the new IOCTL VDUSE_GET_RECONNECT_INFO userspace app will use this information to mmap the memory
Will send the patch for DPDK later
Tested in vduse + dpdk test-pmd
