[Valgrind-developers] Upgrade to GNU General Public License version 3

[Mark W. <ma...@kl...>]

Hi,

We discussed this on this list, with the core valgrind developers and
the FSF Licensing and Compliance Lab what the correct way was to do
this.

The patch itself is a little too big to post to the list, but you can
see it here:
https://code.wildebeest.org/git/user/mjw/valgrind/log/?h=gplv3

There are two patches, one cleanup:

    Update where to get a copy of the GNU General Public License
    
    Several files still said to write to the Free Software Foundation at a
    particular address. Add a reference to <http://www.gnu.org/licenses/>
    instead.
    
    Some files that were imported into valgrind from other places still
    mention the old address. They should be updated when new versions
    get imported.

And the actual update:

    Upgrade to GNU General Public License version 3
    
    - Update COPYING and VEX/LICENSE.GPL to version 3.
    - Update README, NEWS, docs/manual license and contributing text.
    - Update file headers to say either version 3 of the License,
      or (at your option) any later version.
    - Leave tests and perf file headers as is, unless the code is derived
      from Valgrind/VEX.
    - Leave valgrind.h, cachegrind.h, callgrind.h, drd.h, helgrind.h,
      memcheck.h and dhat.h Hybrid-BSD licensed.

I like to merge these on Friday (Oct 17) before releasing 3.26.0-RC1.

Please let me know if you have any questions or concerns about this
update.

Thanks,

Mark
