Partial fix for the phonon/qt issue 

This patch fixes the phonon/qt issue, if all to-be-upgraded packages are
explicit targets (ie. only not-yet-installed packages are pulled by
resolvedeps). This condition covers the most common situations, for example
it should hold with every -Su operation.

After this patch sync405.py passes, but sync406.py doesn't.

The work is inspired by the patch of Henning Garus, thanks for his work:
http://mailman.archlinux.org/pipermail/pacman-dev/2010-February/010429.html
(I moved the alpm_list_diff computation to sync.c in order to compute it
only once.)
