nfs4: Support callbacks over IPv6

nfs4: Try connecting to all getaddrinfo() results before giving up

nfs4: Make the client more configurable

nfs4: Let GenerateClientID take advantage of PeerAddress methods

nfs4: Add basic RPC level support for callbacks

nfs4: Send the server client's network address

nfs4: Make networking code IP version agnostic

nfs4: Use more meaningful names in Connection and RPCServer

nfs4: Use IPPROTO_* instead of enum Transport

nfs4: Use semaphore to cancel threads instead of interrupt_thread()

Move parsing getattrinfo() result out of dns_resolver module

nfs4: Add ConnectionStream and ConnectionPacket classes

nfs4: k- variants of socket functions are not really needed

nfs4: Add open() hook

nfs4: Fix rpc listener thread cancelation

recv on UDP sockets is not interrupted when the socket is closed.
Additionaly, signals do not interrupt kernel threads, that is why
new function interrupt_thread was implemented in order to cancel
listener thread.

nfs4: Add network code

Connection class supports sending and receiving RPC data using either
TCP or UDP as a transport protocol.
