bpf: net: Change sk_getsockopt() to take the sockptr_t argument
This patch changes sk_getsockopt() to take the sockptr_t argument
such that it can be used by bpf_getsockopt(SOL_SOCKET) in a
latter patch.
security_socket_getpeersec_stream() is not changed. It stays
with the __user ptr (optval.user and optlen.user) to avoid changes
to other security hooks. bpf_getsockopt(SOL_SOCKET) also does not
support SO_PEERSEC.

a31edb2059ed4e498f9aa8230c734b59d0ad797a.
It turns out the idea to share a single pointer for both kernel and user
space address causes various kinds of problems. So use the slightly less
optimal version that uses an extra bit, but which is guaranteed to be safe
everywhere.

net: optimize the sockptr_t for unified kernel/user address spaces
For architectures like x86 and arm64 we don't need the separate bit to
indicate that a pointer is a kernel pointer as the address spaces are
unified. That way the sockptr_t can be reduced to a union of two
pointers, which leads to nicer calling conventions.
The only caveat is that we need to check that users don't pass in kernel
address and thus gain access to kernel memory. Thus the USER_SOCKPTR
helper is replaced with a init_user_sockptr function that does this check
and returns an error if it fails.
