[SR-Users] Doing automatic unregister when a WEBSOCKET connection is closed.

[Peter Dunkley]

Hello,

When the register succeeds store the To-URI in a hash-table indexed on 
$si:$sp.

Make sure the entries in the hash-table do not automatically expire and 
use the sht_rm_name_re() function to remove the entry after you have 
called unregister.

Be careful using unregister() as unless you provide it the ruid for the 
exact location entry it will remove all contacts for that URI, not just 
the one relating to that connection.  unregister() with ruid is only 
available in Git master.  There is currently no way to find out what the 
ruid allocated after a save() is (but you could add this easily 
enough).  Note: none of this is a problem if you are permitting only one 
contact binding per subscriber.
