We already fixed a couple of these in previous patches - this one should
replace all remaining uses of single brackets ("[") by double brackets.
Also, use arithmetic evaluation instead of conditional expressions where
appropriate and make use of "-z" and "-n" instead of comparing variables
to empty strings.

* common.sh is included on build time
* most functions are copied from makepkg

Replace all mktemp(1) invocations that hardcode "/tmp" with `mktemp
--tmpdir` and change templates accordingly.

Note that "--tmpdir" is GNU-ish which is okay given that we currently
support Arch Linux only anyway.

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.
