  [dialog] added support for delayed dialog deletion

Once terminated, instead of deleting / destroying the in-memory dialog right away, by setting the 'delete_delay' parameter, the dialog may be kept for a while in memory, in a read-only state (no action, no changes, nothing).
This delaying may be used to help with the routing of late in-dialog request that may be received after the dialog terminated (like late BYE's due to retransmissions, cross BYE requests, auth'ed BYE request, slow ACK on re-INVITEs, etc).
