libffi4 -> libffi5 transition

[Scott Kitterman]

I was just looking into a FTBFS for a sync I'd requested and discovered that 
libffi4 (that used to be provided by the GCC 4.2 source package) has vanished 
in Intrepid and been replaced by libffi5 provided from a new libffi source 
package.

My current problem turned out to be:

python-gobject: Depends: libffi4 (>= 4.1.1-21) but it is not going to be 
installed

So I looked into rebuilding pygobject in Intrepid so it would build against 
libffi5, but then I notice pygobject is in Main and libffi is still in 
Universe, so even if it works locally, I couldn't fix it in the archive.

I am hoping someone has this on their radar screen and it already working on 
it.  I'm not sure how much breakage this is currently causing, but the list 
of rdepends is not small:
