2db9983a43 tipc: split variable assignments out of conditional expressions
Cleans up TIPC's source code to eliminate assigning values to variables
within conditional expressions, improving code readability and reducing
warnings from various code checker tools.

These changes are purely cosmetic and do not alter the operation of TIPC
in any way.

b0c1e928c8 tipc: Remove user registry subsystem
Eliminates routines, data structures, and files that make up TIPC's
user registry. The user registry is no longer needed since the native
API routines that utilized it no longer exist and there are no longer
any internal TIPC services that use it.

8f92df6ad4 tipc: Remove prototype code for supporting multiple clusters
Eliminates routines, data structures, and files that were intended
to allow TIPC to support a network containing multiple clusters.
Currently, TIPC supports only networks consisting of a single cluster
within a single zone, so this code is unnecessary.

08c80e9a03 tipc: Remove prototype code for supporting slave nodes
Simplifies routines and data structures that were intended to allow
TIPC to support slave nodes (i.e. nodes that did not have links to
all of the other nodes in its cluster, forcing TIPC to route messages
that it could not deliver directly through a non-slave node).

Currently, TIPC supports only networks containing non-slave nodes,
so this code is unnecessary.

Note: The latest edition of the TIPC 2.0 Specification has eliminated
the concept of slave nodes entirely.

d265fef6dd tipc: Remove obsolete native API files and exports
As part of the removal of TIPC's native API support it is no longer
necessary for TIPC to export symbols for routines that can be called
by kernel-based applications, nor for it to have header files that
kernel-based applications can include to access the declarations for
those routines. This commit eliminates the exporting of symbols by
TIPC and migrates the contents of each obsolete native API include
file into its corresponding non-native API equivalent.

The code which was migrated in this commit was migrated intact, in
that there are no technical changes combined with the relocation.

31e3c3f6f1 tipc: cleanup function namespace
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.

c6537d6742 TIPC: Updated topology subscription protocol according to latest spec
This patch makes it explicit in the API that all fields in subscriptions and events exchanged with the Topology Server must be in
network byte order.
It also ensures that all fields of a subscription are compared when cancelling a subscription, in order to avoid inadvertent
cancelling of the wrong subscription.
Finally, the tipc module version is updated to 2.0.0, to reflect the API change.

03194379a7 tipc: Fix initialization sequence problems when entering network mode
This patch ensures that TIPC's topology service and configuration
service are shut down before switching into "network mode".  This
ensures that TIPC does not mistakenly try to send unnecessary
"publication withdraw" messages to other nodes before it is fully
initialized for sending off-node messages.  Note that the node's
current network address is now updated only after the two services
are shut down; this ensures that any existing connections to the
topology server are terminated correctly using the old address.

28353e7fad tipc: Consolidate subscriber & subscriber port references
This patch modifies TIPC's network topology service so that it
only requires a single reference table entry per subscriber
connection, rather than two.  This is achieved by letting the
reference to the server port communicating with the subscriber
act as the reference to the subscriber object itself.  (Since
the subscriber cannot exist without its port, and vice versa,
this dual role for the reference is perfectly natural.)  This
consolidation reduces the size of the reference table by 50%
in the default configuration.
