RIOT default license header change

[LudwigKnuepfer]

Actual text is up for discussion, I think we more or less agreed on this one.

When we agree upon a text, there are some more files to be changed (see license checker output for lgpl* files).

[LudwigKnuepfer]

milestone is FIX ME FIRST because it's part of fixing #392

[LudwigKnuepfer]

Lines for applying a $LICENSE (with some escaped characters):

$ for FILE in $(cat dist/tools/licenses/out/lgpl-short-riot); do
sed -i -e '/This file is subject to the terms and conditions of the GNU Lesser General/,/details/c'${LICENSE} ${FILE}
done

Just for the record, "or any later version" is part of this PR and does not reflect the actual license change from GPLv3 some months ago.

[LudwigKnuepfer]

@kaspar030 Why?
We (would) still license everything as lgplv2.1 only allowing others to relicense.

[kaspar030]

@LudwigOrtmann Exactly. But we decided specifically to use LGPV2.1, not "any later version".

A relicensed fork's changes would be incompatible with "our" codebase.

I hate licences.

[OlegHahm]

I would also vote against importing this "or any later version" here. AFAIK there was no consensus about this (and not all authors were asked).

And I would still vote for longer lines to save some line breaks.

[LudwigKnuepfer]

Did as you suggested.

[LudwigKnuepfer]

Huh, I guess I messed up the license text while rewrapping .... fixing.

[LudwigKnuepfer]

Is this better?

[OlegHahm]

Actually I think I'm the wrong person to review this PR. Is there anyone volunteering?

[LudwigKnuepfer]

rebased, text fixed.

[LudwigKnuepfer]

rebased

[LudwigKnuepfer]

@OlegHahm Do you think we should put this on the mailing list or take it to the next developers meeting? As it is now, it's only a cosmetic header change.

[OlegHahm]

Give it a try on the mailing list, I would say.

[LudwigKnuepfer]

The mailing list refused to answer.

[LudwigKnuepfer]

Nobody seems have anything to say, I suggest I change to the minimal version (compare #1396) - at least nobody dislikes it and it is compatible with the existing one. Then we can merge it and see what the future brings.

[haukepetersen]

I am fine with this license -> ACK (for the long version)

[OlegHahm]

ACK for the short version.

[LudwigKnuepfer]

One more ACK to decide this issue, gogogo =)

[kaspar030]

ACK for the short version, too. (thats not this one, right?)

[LudwigKnuepfer]

@kaspar030 You're right it's not presently visible, I'll update.

[LudwigKnuepfer]

This should be it... phew.

[OlegHahm]

That looks strange.

[OlegHahm]

The rest is ACK.

[LudwigKnuepfer]

fixed and rebased and squashed

[OlegHahm]

ACK.
