Fixes #1494

I went with making sun_path always nul-terminated since that just seems to make things easier, since (at least according to linux man pages) sockaddr_uns returned by the kernel will always be nul-terminated.

Changing the meaning of len in sockaddr_storage_to_addr is a big deal. Can you make that backwards compatible instead?
