Merge branch 'udplite-dccp-print-deprecation-notice'
Kuniyuki Iwashima says:
====================
udplite/dccp: Print deprecation notice.
UDP-Lite is assumed to have no users for 7 years, and DCCP is
orphaned for 7 years too.
Let's add deprecation notice and see if anyone responds to it.
====================
