The function tipc_report_overlap() is called from the binding table
with numerous parameters taken from an instance of struct publication.
A closer look reveals that it always is safe to send along a pointer
to the instance itself, and hence reduce the call signature. We do
that in this commit.

instead of as currently in tipc_service_insert_publ(). This has the
advantage that we can pass a pointer to the publication struct to

In a future commit we will introduce more members to struct publication.
In order to keep this structure comprehensible we now group some of
its current fields into the sub-structures where they really belong,
- A struct tipc_service_range for the functional address the publication
is representing.
- A struct tipc_socket_addr for the socket bound to that service range.
We also rename the stack variable 'publ' to just 'p' in a few places.
This is just as easy to understand in the given context, and keeps the
number of wrapped code lines to a minimum.
There are no functional changes in this commit.

In commit 682cd3cf94
("tipc: confgiure and apply UDP bearer MTU on running links"), we
introduced a function to change UDP bearer MTU and applied this new value
across existing per-link. However, we did not apply this new MTU value at
node level. This lead to packet dropped at link level if its size is
greater than new MTU value.
To fix this issue, we also apply this new MTU value for node level.

The 32-bit node number, aka node hash or node address, is calculated
based on the 128-bit node identity when it is not set explicitly by
the user. In future commits we will need to perform this hash operation
on peer nodes while feeling safe that we obtain the same result.
We do this by interpreting the initial hash as a network byte order
number. Whenever we need to use the number locally on a node
we must therefore translate it to host byte order to obtain an
architecure independent result.
Furthermore, given the context where we use this number, we must not
allow it to be zero unless the node identity also is zero. Hence, in
the rare cases when the xor-ed hash value may end up as zero we replace
it with a fix number, knowing that the code anyway is capable of
handling hash collisions.
