Improve handling of addresses on ldpe.

This is a preliminary work for the the next patch (sigup config
reload). We want to make sure that the ldpe process can handle duplicated
addresses.

The idea is to alloc two different if_addr structures for each address,
and link one in the global list of addresses (used to send address
messages) and link the other to the associated interface list of
addresses.

Doing that we will be able to call kif_redistribute() after reloading
the config file and activate the new LDP enabled interfaces.

NOTE: Interfaces are created at config parse time and the child
processes inherit them on fork() so there's no need to send a status
update at startup.
