Add GPLv2+ COPYING file as there's a few files still licensed as GPL-2+

Review Request #125925 - Created Nov. 2, 2015 and submitted

Diane Trout

This is still code from Marcin Ziemi?ski but is using a valid license
so I'm less sure I could just relicense it. I think adding the COPYING file
would be acceptable to Debian FTP-Master, or we could relicense the
code to be LGPL-2.1+.

KTp/OTR/channel-adapter.cpp GPL (v2 or later)
KTp/OTR/channel-adapter.h GPL (v2 or later)
KTp/OTR/utils.cpp GPL (v2 or later)
KTp/OTR/utils.h GPL (v2 or later)

Any preferences on what should be done?

Added a text file. no testing done.
