update-autogen: new tool to generate module autogen.sh files from a common template

Maybe one day an autogen.sh consisting of just 'autoreconf' will
be enough. Until then, let's try to at least use consistent autogen.sh
in the different modules. This tool will hopefully help with that.

The autogen.sh.in template is currently based on the autogen.sh
from core. There are changes in other modules which should probably
be merged into that.

One bug has already been fixed: touch gstreamer-1.0.pot not -0.10.pot
