tipc: simplify include dependencies
When we try to add new inline functions in the code, we sometimes run into circular include dependencies. The main problem is that the file core.h, which really should be at the root of the dependency chain, instead is a leaf. I.e., core.h includes a number of header files that themselves should be allowed to include core.h. In reality this is unnecessary, because core.h does not need to know the full signature of any of the structs it refers to, only their type declaration. In this commit, we remove all dependencies from core.h towards any other tipc header file. As a consequence of this change, we can now move the function tipc_own_addr(net) from addr.c to addr.h, and make it inline. There are no functional changes in this commit.
