Currently, a number of structure and function definitions related to the broadcast functionality are unnecessarily exposed in the file bcast.h. This obscures the fact that the external interface towards the broadcast link in fact is very narrow, and causes unnecessary recompilations of other files when anything changes in those definitions. In this commit, we move as many of those definitions as is currently possible to the file bcast.c. We also rename the structure 'tipc_bclink' to 'tipc_bc_base', both since the name does not correctly describe the contents of this struct, and will do so even less in the future, and because we want to use the term 'link' more appropriately in the functionality introduced later in this series. Finally, we rename a couple of functions, such as tipc_bclink_xmit() and others that will be kept in the future, to include the term 'bcast' instead. There are no functional changes in this commit.
