Add InfiniBand media type based on the ethernet media type.

The only real difference is that in case of InfiniBand, we need the entire
20 bytes of space reserved for media addresses, so the TIPC media type ID is
not explicitly stored in the packet payload.

Sample output of tipc-config:

# tipc-config -v -addr -netid -nt=all -p -m -b -n -ls

The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

There used to be a time when TIPC had lots of Kconfig knobs the
end user could alter, but they have all been made automatic or
obsolete, with the exception of CONFIG_TIPC_PORTS.  This
previously existing set of options was all hidden under the
TIPC_ADVANCED setting, which does not exist in any code, but
only in Kconfig scope.

Having this now, just to hide the one remaining "advanced"
option no longer makes sense.  Remove it.  Also get rid of the
ifdeffery in the TIPC code that allowed for TIPC_PORTS to be
possibly undefined.

The internal log buffer handling functions can now safely be
removed since there is no code using it anymore.  Requests to
interact with the internal tipc log buffer over netlink (in
config.c) will report 'obsolete command'.

This represents the final removal of any references to a
struct print_buf, and the removal of the struct itself.
We also get rid of a TIPC specific Kconfig in the process.

Finally, log.h is removed since it is not needed anymore.

The link queue traces and packet level debug functions served
a purpose during early development, but are now redundant
since there are other, more capable tools available for
debugging at the packet level.

The TIPC_DEBUG Kconfig option is removed since it does not
provide any extra debugging features anymore.

This gets rid of a lot of tipc_printf usages, which will
make the pending cleanup work of that function easier.

Gets rid of the need for users to specify the maximum number of
cluster nodes supported by TIPC. TIPC now automatically provides
support for all 4K nodes allowed by its addressing scheme.

Note: This change sets TIPC's memory usage to the amount used by
a maximum size node table with 4K entries.  An upcoming patch that
converts the node table from a linear array to a hash table will
compact the node table to a more efficient design, but for clarity
it is nice to have all the Kconfig infrastruture go away separately.

Cleans up TIPC's source code to eliminate deviations from generally
accepted coding conventions relating to leading/trailing white space
and white space around commas, braces, cases, and sizeof.

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

Completes the simplification of TIPC's debugging capabilities. By default
TIPC includes no debugging code, and any debugging code added by developers
that calls the dbg() and dbg_macros() is compiled out. If debugging support
is enabled, TIPC prints out some additional data about its internal state
when certain abnormal conditions occur, and any developer-added calls to the
TIPC debug macros are compiled in.

to allow TIPC to support a network containing multiple clusters.
Currently, TIPC supports only networks consisting of a single cluster

This patch addresses a number of minor (mostly cosmetic) issues relating
to the configuration of TIPC, including the following:

- Corrects range limits for maximum number of ports per node
- Adds missing range limits for size of log buffer
- Removes configuration setting relating to unsupported slave node capability
- Standardizes description and help text wording for configuration settings
- Removes unneeded blank spaces

We can rely on kconfig to limit these numbers,
no need to limit them at compile time/run time.

Users who modify these numbers manually should
be responsible for themself. :)
