9a0dfc3c55 unix: implement L2TPIP socket address on Linux
Add constants and types to support IP-encapsulated L2TP/RFC3931
tunnels on Linux systems.

The L2TP subsystem for IP encapsulated tunnels hooks into the inet
kernel code using a specific IP protocol value.  In order to handle
this, anyToSockaddr now has to query the socket protocol type using
GetsockoptInt for the AF_INET and AF_INET6 address families.

Although this change is reasonably simple, unit tests have been added
to validate handling of the new types.

Fixes golang/go#37787

b69606af41 unix: comply with -d=checkptr in Test_anyToSockaddr
Rather than directly casting between types of different sizes, use an
explicit copy in a helper function.

43c01164e9 unix: implement AF_TIPC sockets on Linux
Adds initial constants and types to use with SockaddrTIPC. For more
information on TIPC, see: http://tipc.sourceforge.net/.

Because the C struct sockaddr_tipc makes use of a union for its addr
field, I have created a wrapping layer in SockaddrTIPC that uses
an interface to determine which variant is in use.

Tests accompany this change due to the complexity of this code. There
is currently little test coverage in the Sockaddr-related code, but
perhaps this is something that could be picked up as a relatively
straightforward task for a new contributor.
