Exchange custom netlink fork for neli crate

[marcelbuesing]

This removes the custom netlink dependency in exchange for the neli-crate. I have tested bring_up and bring_down and it seems to work. There is a minor difference in the send that I have not figured out yet why sa_family is not added in neli or if that is even relevant since it has the intended effect.

strace -s 100 -f -x of

    let iface = CanInterface::open("vcan0").expect("Failed to lookup vcan0 iface");
    iface.bring_down().unwrap();

netlink-rs fork:

bind(3, {sa_family=AF_NETLINK, nl_pid=29418, nl_groups=00000000}, 16) = 0
sendto(3, {{len=32, type=RTM_NEWLINK, flags=NLM_F_REQUEST|NLM_F_ACK, seq=0, pid=0}, {ifi_family=AF_UNSPEC, ifi_type=ARPHRD_NETROM, ifi_index=if_nametoindex("vcan0"), ifi_flags=0, ifi_change=0x1}}, 32, 0, {sa_family=AF_NETLINK, nl_pid=0, nl_groups=00000000}, 16) = 302
recvfrom(3, {{len=36, type=NLMSG_ERROR, flags=NLM_F_CAPPED, seq=0, pid=29418}, {error=0, msg={len=32, type=RTM_NEWLINK, flags=NLM_F_REQUEST|NLM_F_ACK, seq=0, pid=0}}}, 4096, 0, {sa_family=AF_NETLINK, nl_pid=0, nl_groups=00000000}, [16->12]) = 36

neli:

bind(3, {sa_family=AF_NETLINK, nl_pid=960, nl_groups=00000000}, 12) = 0
sendto(3, {{len=32, type=RTM_NEWLINK, flags=NLM_F_REQUEST|NLM_F_ACK, seq=0, pid=0}, {ifi_family=AF_UNSPEC, ifi_type=ARPHRD_NETROM, ifi_index=if_nametoindex("vcan0"), ifi_flags=0, ifi_change=0x1}}, 32, 0, NULL, 0) = 32
recvfrom(3, {{len=36, type=NLMSG_ERROR, flags=NLM_F_CAPPED, seq=0, pid=960}, {error=0, msg={len=32, type=RTM_NEWLINK, flags=NLM_F_REQUEST|NLM_F_ACK, seq=0, pid=0}}}, 32768, 0, NULL, NULL) = 36

WIP: since this is still waiting for merge of: jbaublitz/neli#61, I will exchange the git link for a version once that is released.

I merged this into my fork at:
https://github.com/fpagliughi/socketcan-rs/tree/develop

There were a number of breaking changes in neli since this PR was done, but I fixed those up and hit a serialization error:
jbaublitz/neli#136

But now that's all working. I still need to re-implement the wait-for-ack functionality which changed in the library, but overall neli does look like a better choice for dealing with the Netlink stuff.

I think neli 0.5.3 that was released yesterday should contain the fix?
