ipv6: introduce secret_stable to ipv6_devconf
This patch implements the procfs logic for the stable_address knob:
The secret is formatted as an ipv6 address and will be stored per
interface and per namespace. We track initialized flag and return EIO
errors until the secret is set.
We don't inherit the secret to newly created namespaces.
