Do IPv6 Stateless Address Auto-Configuration (SLAAC)
This change allows the netstack to do SLAAC as outlined by RFC 4862 section 5.5.
Note, this change will not break existing uses of netstack as the default
configuration for the stack options is set in such a way that SLAAC
will not be performed. See `stack.Options` and `stack.NDPConfigurations` for
more details.
This change reuses 1 option and introduces a new one that is required to take
advantage of SLAAC, all available under NDPConfigurations:
- HandleRAs: Whether or not NDP RAs are processes
- AutoGenGlobalAddresses: Whether or not SLAAC is performed.
Also note, this change does not deprecate SLAAC generated addresses after the
preferred lifetime. That will come in a later change (b/143713887). Currently,
only the valid lifetime is honoured.
Tests: Unittest to make sure that SLAAC generates and adds addresses only when
configured to do so. Tests also makes sure that conflicts with static addresses
do not modify the static address.
