tipc: add function for checking broadcast support in bearer
As a preparation for the 'replicast' functionality we are going to introduce in the next commits, we need the broadcast base structure to store whether bearer broadcast is available at all from the currently used bearer or bearers. We do this by adding a new function tipc_bearer_bcast_support() to the bearer layer, and letting the bearer selection function in bcast.c use this to give a new boolean field, 'bcast_support' the appropriate value.
