This build system overhaul allows for adding (define-style) macros to
our scripts. All source files are now suffixed with ".in" to clarify
that they might contain unprocessed defines. The Makefile provides a new
rule to preprocess source files and generate proper output scripts.

Also, add a "@pkgdatadir@" define (as used in GNU Autotools) and use it
instead of hardcoded paths to "/usr/share/devtools" everywhere. We
missed this when adding PREFIX support to the build system in commit
35fc83ce.

Add the same vim modeline to all the files, as well as cleanup the newly
added scripts a bit. If you look at this diff with the -w option, you'll see
it really isn't all that significant.
