tipc: Combine port structure with tipc_port structure
Merge two distinct structures containing information about a TIPC port into a single structure. The structures were previously kept separate so that public information about a port could be made available to applications using TIPC's native API, while the remaining information was kept private for use by TIPC itself. However, now that the native API has been removed there is no longer any need for this somewhat confusing arrangement. Since one of the structures was already embedded within the other, the change largely involves replacing instances of "publ.foo" with "foo". The changes do not otherwise alter the operation of TIPC ports. Signed-off-by: Allan Stephens <Allan.Stephens@windriver.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
