Release kmscon-7

Release kmscon-7

This is kmscon-7. See ./NEWS for a list of new features.

Unfortunately, github disabled the "Downloads" section so there is no way
to upload new pre-generated tarballs. I have a pending application to move
kmscon to freedesktop.org, but it didn't get processed in time for this
release. Therefore, you need to build the GNU-autotools files yourself.
That is, before calling ./configure you need to call:
  NOCONFIGURE=1 ./autogen.sh

You can extend your build-scripts with:
  test -f ./configure || NOCONFIGURE=1 ./autogen.sh

Which will call ./autogen.sh if needed. Everything else can be left
unchanged.

I will not upload the tarballs at another location. Feel free to do that
yourself, but I personally think this will introduce more confusion than
help. I hope the freedesktop.org move will be soon approved. This will
also provide a mailing-list where I can properly announce new releases.

Raw tarballs will be available as (without pre-generated autotools):
  https://github.com/dvdhrm/kmscon/archive/kmscon-7.tar.gz
  https://github.com/dvdhrm/kmscon/archive/kmscon-7.zip

The git-tag is: kmscon-7
You can use my public GPG key to verify the tarballs.

As usual, please report bugs to: https://github.com/dvdhrm/kmscon
