tipc: Merge port and socket layer code

After the removal of the TIPC native interface, there is no reason to
keep a distinction between a "generic" port layer and a "specific"
socket layer in the code. Throughout the last months, we have posted
several series that aimed at facilitating removal of the port layer,
and in particular the port_lock spinlock, which in reality duplicates
the role normally kept by lock_sock()/bh_lock_sock().

In this series, we finalize this work, by making a significant number of
changes to the link, node, port and socket code, all with the aim of
reducing dependencies between the layers. In the final commits, we then
remove the port spinlock, port.c and port.h altogether.

After this series, we have a socket layer that has only few dependencies
to the rest of the stack, so that it should be possible to continue
cleanups of its code without significantly affecting other code.
