[undertow-dev] Proxy Protocol v2 support

[Ulrich Herberg]

Here is the Pull Request: https://github.com/undertow-io/undertow/pull/699

Let me know if you have questions or propose changes. Currently, TCP over
IPv4 and IPv6 and the LOCAL protocol is supported. UDP and Unix sockets
aren't. I tested this successfully on AWS with a Network Load Balancer and
Proxy Protocol v2 enabled. It would be good to test with Proxy protocol v1
as well, just to make sure I didn't break that. The code will automatically
determine which version is used.
