Michael Pratt 74e04506a4 Prefer Type& over Type &
And Type* over Type *. This is basically a whitespace only change.

gVisor code already prefers left-alignment of pointers and references, but
clang-format formats for consistency with the majority of a file, and some
files leaned the wrong way. This is a one-time pass to make us completely
conforming.

Michael Pratt b23b36e701 Add NETLINK_KOBJECT_UEVENT socket support
NETLINK_KOBJECT_UEVENT sockets send udev-style messages for device events.
gVisor doesn't have any device events, so our sockets don't need to do anything
once created.

systemd's device manager needs to be able to create one of these sockets. It
also wants to install a BPF filter on the socket. Since we'll never send any
messages, the filter would never be invoked, thus we just fake it out.

Fixes #1117
Updates #1119

Andrei Vagin af90e68623 netlink: return an error in nlmsgerr
Now if a process sends an unsupported netlink requests,
an error is returned from the send system call.

The linux kernel works differently in this case. It returns errors in the
nlmsgerr netlink message.
