tipc: refractor bearer to facilitate link monitor

Browse Source 
In this commit, we:
1. Export print_bearer_media()
2. Move the bearer name handling from nl_add_bearer_name() into
   a new function cmd_get_unique_bearer_name().

These exported functions will be used by link monitor used in
subsequent commits.
