libndp: add option flags to send messages
Within NA and RA message types, there are flags such as Solicited and Override
(RFC-4861 Section 4). RA flags are currently implemented but not NA flags, so
add remaining NA flag getters/setters.
Set Solicited/Override flag on NA when appropriate, add a flags interface to
the send API, and implement ability to send Unsolicited NA.
