Ipv6 incl hop limit

[andreybuchinskiy]

Adding support for enabling IPV6_RECVHOPLIMIT on sockets for Linux OS

Clippy is failing, but it is also failing on master. I can make the required changes to make Clippy happy if necessary.

Forgot to ask last time, can you add a test? A basic set & get should be sufficient, see tests/socket.rs.

Thanks @andreybuchinskiy

GitHub shows that this commit is contained in master:
https://github.com/rust-lang/socket2/commits/v0.5.x/

IntelliJ shows that this commit is contained in v0.5.x and master 🙈

When I run cargo package these changes are part of the source artifact... so my best guess still is that they are contained in 0.5.9 😄

Can you update the Branches section in the README to reflect the current release and development branches?
