Support non-standard install locations
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 35fc83ce7d8dc26cd424321f2e8638d05da0a6d4. Signed-off-by: Lukas Fleischer <archlinux@cryptocrack.de>
