sctp: Mark GET_PEER|LOCAL_ADDR_OLD deprecated.

Browse Source 
Socket options SCTP_GET_PEER_ADDR_OLD, SCTP_GET_PEER_ADDR_NUM_OLD,
SCTP_GET_LOCAL_ADDR_OLD, and SCTP_GET_PEER_LOCAL_ADDR_NUM_OLD
have been replaced by newer versions a since 2005.  It's time
to officially deprecate them and schedule them for removal.

@ -312,3 +312,15 @@ When: 2.6.26
Why: Implementation became generic; users should now include
linux/semaphore.h instead.
Who: Matthew Wilcox <willy@linux.intel.com>
---------------------------
What: SCTP_GET_PEER_ADDRS_NUM_OLD, SCTP_GET_PEER_ADDRS_OLD,
SCTP_GET_LOCAL_ADDRS_NUM_OLD, SCTP_GET_LOCAL_ADDRS_OLD
When: June 2009
Why: A newer version of the options have been introduced in 2005 that
removes the limitions of the old API. The sctp library has been
converted to use these new options at the same time. Any user
space app that directly uses the old options should convert to using
the new options.
