second call: please nail down the license terms of some more modules

[Bruno Haible]

Hi all,

There was no objection when I said that: the majority of gnulib modules will
migrate from GPLv2+ to GPLv3+ and from LGPLv2+ to LGPLv3+. So I assume we can
go for it in a few days?

Before that, please mark the modules that you want to stay at the current
license. We can also revert a license change for a module afterwards, if all
contributors agree, but it's easier if it can be done upfront, because then
it's legally a no-op.

Bruno
