tipc: Cosmetic cleanup of system & debug output declarations

This patch contains changes to make TIPC's system & debug
message declarations more readable.  Declarations have been
regrouped and recommented to make it easier to understand
what output is generated in both standard and debugging modes.
In addition, oversize lines have been fixed to respect the
80 character upper bound used in the kernel.
