3a9e75374f conn: disable sticky sockets on Android
We can't have the netlink listener socket, so it's not possible to
support it. Plus, android networking stack complexity makes it a bit
tricky anyway, so best to leave it disabled.

07a1e55270 conn: fix getSrcFromControl() iteration
We only expect a single control message in the normal case, but this
would loop infinitely if there were more.

7d327ed35a conn: use right cmsghdr len types on 32-bit in sticky test
Cmsghdr uses uint32 and uint64 on 32-bit and 64-bit respectively for the
Len member, which makes assignments and comparisons slightly more
irksome than usual.

9e2f386022 conn, device, tun: implement vectorized I/O on Linux
Implement TCP offloading via TSO and GRO for the Linux tun.Device, which
is made possible by virtio extensions in the kernel's TUN driver.

Delete conn.LinuxSocketEndpoint in favor of a collapsed conn.StdNetBind.
conn.StdNetBind makes use of recvmmsg() and sendmmsg() on Linux. All
platforms now fall under conn.StdNetBind, except for Windows, which
remains in conn.WinRingBind, which still needs to be adjusted to handle
multiple packets.

Also refactor sticky sockets support to eventually be applicable on
platforms other than just Linux. However Linux remains the sole platform
that fully implements it for now.
