Do some cleanups of TIPC based on make namespacecheck
1. Don't export unused symbols
2. Eliminate dead code
3. Make functions and variables local
4. Rename buf_acquire to tipc_buf_acquire since it is used in several files
Compile tested only.
This make break out of tree kernel modules that depend on TIPC routines.

Remove all instances of legacy, or as yet to be implemented code
that is currently living within an #if 0 ... #endif block.
In the rare instance that some of it be needed in the future,
it can still be dragged out of history, but there is no need
for it to sit in mainline.

Ensure that TIPC does not re-establish communication with a
neighboring node until it has finished updating all data structures
containing information about that node to reflect the earlier loss of
contact. Previously, it was possible for TIPC to perform its purge of
name table entries relating to the node once contact had already been
re-established, resulting in the unwanted removal of valid name table
entries.

These functions have enough code in them such that they
seem like sensible targets for un-inlining. Prior to doing
that, this adds the tipc_ prefix to the functions, so that
in the event of a panic dump or similar, the subsystem from
which the functions come from is immediately clear.

Rather than live in link.c where they can only be used in that file alone,
these helper routines are better served by being in link.h
Relocated are the following:
link_working_working
link_working_unknown
link_reset_unknown
link_reset_reset
link_blocked
link_congested

Andrew Morton reported a build failure on sparc32, because TIPC
uses names like "struct node" and there is a like named data
structure defined in linux/node.h
This just regexp replaces "struct node*" to "struct tipc_node*"
to avoid this and any future similar problems.

This patch eliminates the rarely-used "error code" argument
when initializing a TIPC message header, since the default
value of zero is the desired result in most cases; the few
exceptional cases now set the error code explicitly.

This patch enhances TIPC's handler for incoming messages in two
ways:
- the trivial, single-use routine for processing non-sequenced
messages has been merged into the main handler
- the interface that received a message is now identified without
having to access and/or modify the associated sk_buff

This patch corrects an issue wherein a previouly failed node could
not reestablish a links to a non-failing node in the TIPC network
until the latter node detected the link failure itself (which might
be configured to take up to 30 seconds). The non-failing node now
responds to link setup requests from a previously failed node in at
most 1 second, allowing it to detect the link failure more quickly.

TIPC now rejects and logs link setup requests from node <Z.C.N> if the
receiving node already has a functional link to that node on the associated
interface, or if the requestor is using the same <Z.C.N> as the receiver.
