[AD] Grabber and vsnprintf

[Evert Glebbeek <eglebbk@xxxxxxxxxx>]

I'd used vsnprintf a few times in the grabber, but it seems to be C99 only.
The attached patch changes it to uvszprintf, which seems to work just fine 
despite not setting the encoding.
There are quite a few calls to vsprintf() in dat that we should probably 
also change for good measure.
