tipc: Add routines for safe checking of node's network address
Introduces routines that test whether a given network address is equal to a node's own network address or if it lies within the node's own network cluster, and which work properly regardless of whether the node is using the default network address <0.0.0> or a non-zero network address that is assigned later on. In essence, these routines ensure that address <0.0.0> is treated as an alias for "this node", regardless of which network address the node is actually using. Old users of the pre-existing more strict match in_own_cluster() have been accordingly redirected to what is now called in_own_cluster_exact() --- which does not extend matching to <0,0,0>.
