[PATCH] Add do-release.sh

[Tom de Vries <tdevries@suse.de>]

Hi,

this commit adds a script that:
- bumps either the minor or the major version, using options
  --major or --minor
- updates VERSION
- commits VERSION update
- tags VERSION update

OK for trunk?

Is there anything else involved in doing a release?

Thanks,
- Tom
