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.

In this patch we introduce the ability to get UDP specific bearer
options such as remoteip, remoteport, localip and localport.
After some discussions on tipc-discussion on how to handle media
specific options we agreed to pass them after the media.
For media generic bearer options we already do:
$ tipc bearer get OPTION media MEDIA name|device NAME|DEVICE
For the UDP media specific bearer options we introduce in this path:
$ tipc bearer get media udp name NAME OPTION
such as
$ tipc bearer get media udp name NAME remoteip
This allows bash-completion to tab complete only appropriate options,
it makes more logical sense and it scales better. Even though it might
look a little different to the user.
In order to use the existing option parsing framework to do this we
add a flag (OPT_KEY) to the option parsing function.
If the UDP bearer has multiple remoteip addresses associated with it
(replicast) we handle the TIPC_NLA_UDP_MULTI_REMOTEIP flag and send
a TIPC_NL_UDP_GET_REMOTEIP query transparently to the user.

Introduce the ability to add remote IP addresses to an existing UDP
bearer. On the kernel side, adding a "remoteip" to an existing bearer
puts the bearer in "replicast" mode where TIPC multicast messages are
send out to each configured remoteip using unicast. This is required
for TIPC UDP bearers to work in environments where IP multicast is
disabled.

Introduce a generic function (nl_add_bearer_name()) that identifies a
bearer and adds it to an existing netlink message. This reduces code
complexity and makes the code a little bit easier to maintain.

tipc is a user-space configuration tool for TIPC (Transparent
Inter-process Communication). It utilizes the TIPC netlink API in the
kernel to fetch data or perform actions.
The tipc tool has somewhat similar syntax to the ip tool meaning that
users of the ip tool should not feel that unfamiliar with this tool.
