Merge remote-tracking branch 'remotes/riku/linux-user-for-upstream' into staging 

* remotes/riku/linux-user-for-upstream:
  linux-user: use TARGET_SA_ONSTACK in get_sigframe
  alloca one extra byte sockets
  linux-user: handle AF_PACKET sockaddrs in target_to_host_sockaddr
  qemu-user: Impl. setsockopt(SO_BINDTODEVICE)
  SIOCGIFINDEX: fix typo
