add debian packaging for MeeGo 1.2 Harmattan
debian: add the aegis manifest file

We need ptrace permissions.
debian: rename debian/ to debian_harmattan/

At the moment we maintain two git branches 'master' and 'harmattan'.
The harmattan branch always has to be rebased to master as it just
has the debian packaging for MeeGo 1.2 Harmattan on top. This is
cumbersome and we still want to show that we don't have any Debian
packaging for regular desktop PCs.

So rename the debian directory to debian_harmattan. A further patch
will enhance autogen.sh to set a 'debian' symlink to it if the MeeGo
1.2 Harmattan platform is detected.
autogen: add machine check setting 'debian' symlink

It is likely that we need to maintain multiple 'debian' directories
in the future. So handle setting the correct symlink named 'debian'
in autogen.sh. For now we just detect the MeeGo 1.2 Harmattan
platform as it always needs Debian packaging.
