Updated glibtop_get_proc_open_files API so that it also list IPv6 TCP sockets.

Patch by Mark McClelland <mark@ovcam.org>.
Closes #528175.

WTH do we not care about udp ?

Updated libtool versioning: API addition does not change the ABI, so only
increased revision. gnome-2.22 is 8.1.1 so trunk is now 8.2.1.
