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

The optdepends array should be unset before sourcing the PKGBUILD to avoid
dangling optional depends.

Using parameter substitution might result in unpredictable behaviour
when directories contain whitespaces here. The read shell builtin is the
proper way to read single lines.

Source the PKGBUILD using the correct path (relative to our base
directory) instead of using cd(1) to switch to the ABS base directory
first and to the package directory afterwards.

This is very useful when trying to track errors, also:

    $ ~/src/devtools/finddeps libdaq
    ./community/snort (depends)
    PKGBUILD: line 17: ruby: command not found
    PKGBUILD: line 19: [: =: unary operator expected

Versus:

    $ ~/src/devtools/finddeps libdaq
    ./community/snort (depends)
    ./community/ruby-pkgconfig/PKGBUILD: line 17: ruby: command not found
    ./community/lmms/PKGBUILD: line 19: [: =: unary operator expected

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.
