Merge branch 'configs' into master.

The original setup used parts of the configure.ac to generate the
driver table. These parts are now in the configs directory, and
the scripts generating the table have been updated to use this
as input instead. Basically, this means that "doc/make release" once
again does it's work.

The setuo.sh script is outdated, not taking the new kernel drivers
into account. However, it has some information which might be
valuable if we manage to get some support for configuring kernel
drivers, so it's saved in the configs dir for reference.
