BUG/MINOR: peers: Inconsistency when dumping peer status codes.

A peer connection status must be considered as valid only if there is an applet
which has been instantiated for the connection to the peer. So, ->statuscode
should be considered as the last known peer connection status from the last
connection to this peer if any. To reflect this, "statuscode" field of peer dump
is renamed to "last_statuscode".
This patch also add "active"/"inactive" field after the peer location type
("remote" or "local") if an applet has been instantiated for this peer connection
or not.

Thank you to Emeric for having noticed this issue.

Must be backported in >=1.9 version.
