avviddec: drain frames until libav doesn't have more data

Browse source 
We use have_data (that comes from libav), instead of only trying 10 times,
to know if there are more frames available. The old code was machine
dependant as different amount of frames could be decoded by different
type of (more powerful) machines, and 10 times was not always sufficient.
