tipc: name tipc name table support net namespace
TIPC name table is used to store the mapping relationship between TIPC service name and socket port ID. When tipc supports namespace, it allows users to publish service names only owned by a certain namespace. Therefore, every namespace must have its private name table to prevent service names published to one namespace from being contaminated by other service names in another namespace. Therefore, The name table global variable (ie, nametbl) and its lock must be moved to tipc_net structure, and a parameter of namespace must be added for necessary functions so that they can obtain name table variable defined in tipc_net structure.
