This patch enables TIPC's topology server code to do customized
overlap detection handling on a per-subscription basis. (This
capability is needed to support the upcoming introduction of
multi-cluster TIPC networks.)

This patch eliminates the (very remote) chance of a crash resulting
from a partially initialized socket or native port unexpectedly
receiving a message. Now, during the creation of a socket or native
port, the underlying generic port's lock is not released until all
initialization required to handle incoming messages has been done.

This patch allows a TIPC application to cancel an existing
topology service subscription by re-requesting the subscription
with the TIPC_SUB_CANCEL filter bit set. (All other bits of
the cancel request must match the original subscription request.)

locking init cleanups:
- convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK()
- convert rwlocks in a similar manner
this patch was generated automatically.
Motivation:
- cleanliness
- lockdep needs control of lock initialization, which the open-coded
variants do not give
- it's also useful for -rt and for lock debugging in general

With reference to latest discussions on linux-kernel with respect to
inline here is a patch for tipc to remove all inlines as used in
the .c files. See also chapter 14 in Documentation/CodingStyle.
Before:
text data bss dec hex filename
102990 5292 1752 110034 1add2 tipc.o
Now:
text data bss dec hex filename
101190 5292 1752 108234 1a6ca tipc.o
This is a nice text size reduction which will improve icache usage.
In some cases bigger (> 4 lines) functions where declared inline
and used in many places, they are most probarly no longer inlined by gcc
resulting in the size reduction.
There are several one liners that no longer are declared inline, but gcc
should inline these just fine without the inline hint.
With this patch applied one warning is added about an unused static
function - that was hidded by utilising inline before.
The function in question were kept so this patch is solely a
inline removal patch.

Tried to run the new tipc stack through sparse.
Following patch fixes all cases where 0 was used
as replacement of NULL.
Use NULL to document this is a pointer and to silence sparse.
This brough sparse warning count down with 127 to 24 warnings.
