    modules/sca: fix return value of sca_call_info_uri_update()
    
    - return value of 0 can bubble up as return value of sca_call_info_update(),
      causing early script termination (exported function returning 0 in script
      is equivalent to "exit")
    - report and patch from Timo Teräs

    modules/sca: detect when an AoR is no longer SCA.
    
    Don't, for example, create an appearance for callees that do not send
    a Call-Info header, and whose AoR also has no subscribers.

    modules/sca: Clear stale line-seize appearances via timer.
    
    Some badly behaved/buggy UAs don't know when to say when.

    modules/sca: clear appearance on receipt of out-of-dialog SUBSCRIBE
    
    - If a call-info SUBSCRIBE with no To-tag arrives from a subscriber
      with an active subscription, release any appearances owned by the
      subscriber, on the assumption that the subscriber has lost track
      of SCA (reboot, power/network loss).

    modules/sca: detect and clear orphaned appearances caused by answer glare
    
    - set appearance state created by SCA callee answer to ACTIVE_PENDING,
      and promote to ACTIVE on ACK from caller. If no ACK from caller is
      received within 30 seconds (enough time for retransmission to fail),
      the ACTIVE_PENDING appearance will be cleared by the
      sca_appearance_purge_stale timer.

    modules/sca: reconcile Contact and From URIs in ACK callback.
    
    - fix Music-on-Hold in Polycoms when SCA caller has MoH enabled and SCA callee
      does SCA hold/pickup with identical To & From URIs. Previously, module would
      end up looking up an appearance for callee in ACK callback instead of caller.

    - Clear appearances for both legs on BYE request if possible.

    modules/sca: change logging level for failed lookup by appearance-index.
    
    - appearance-index won't be found yet if SCA callee is answering, logging
      at WARN is misleading.

      Call-Info header inclusion.

    modules/sca: use DB fetch queries when restoring subscribers from database.
    
    - Previously used standard query, exhausting pkg memory when subscriber
      count is high.

    modules/sca: clear appearance on t_reply with error after receiving 18x.
    
    - Receiving a 18x provisional reply triggers line-seize subscription
      termination. Releasing the seized appearance while processing a t_reply
      with an error status *after* getting a 18x would fail because
      sca_subscription_terminate could not find a matching line-seize
      subscription. In that case, look up appearance by tags and release it.
