Kernel: Use Userspace<T> for the getsockopt syscall and Socket interface

Browse source 
The way getsockopt is implemented for socket types requires us to push
down Userspace<T> using into those interfaces. This change does so, and
utilizes proper copy implementations instead of the kind of haphazard
pointer dereferencing that was occurring there before.
