fix: allocate "any" socket type then cast

Otherwise, we're casting from a smaller type to a bigger type,
addressing memory that's not ours.

fixes #19

fix: remove CGO functions

These aren't actually used by anyone anywhere and they'll lead to build errors
if:

1. GCC isn't installed.
2. CGO_ENABLED isn't set to 0.

fix: build without CGO

add gomod support // tag v0.0.1.

Just repair a commentate mistake.

The commentate of function SockaddrToIPAndZone is same with
IPAndZoneToSockaddr. Repaired.

don't panic on 4byte IP addresses

1. Never panic.
2. Only return a unspecified address if the IP is nil (no other random error
cases).
3. Simplify the logic.

They're valid.

Add basic .travis.yml file.

set the V4InV6Prefix correctly (like go does)

This is why go uses 16 byte arrays for all addresses by default.

fix windows support

1. Switch back to the syscall package for errors. That way, we get consistent
   errors on all platforms.
2. Use `sys/windows` where appropriate.
3. Export type aliases for the *Sockaddr* types. That way, we can use the
   platform-specific types but call them the same name, regardless of platform.

switch to golang.org/x/sys

syscall is frozen and mostly deprecated.
