Add a list of SRv6 locator chunks allocated to a specific IS-IS area. The list is initialized when the IS-IS area is created and freed when the IS-IS area is destroyed. Subsequent commits will introduce the possibility to allocate and release locator chunks. Signed-off-by: Carmine Scarpitta <carmine.scarpitta@uniroma2.it>
