QtMoko pulseaudio patches

[Neil Jerram]

Hi Radek,

Here are some minor patches related to pulseaudio, for your
consideration.

The first one may not be quite right, because my impression from Gilles'
recent change is that perhaps debian/control should now be generated
from some other file?  (or perhaps the same change should be made in
other places?)  So please either tweak or bounce that back to me for
revision.

The other two are straightforward, I believe.

Regards,
        Neil
