The lavfi avdevice as it is right now can't output "special frames"
like hardware frames.
This patch makes the lavfi avdevice output wrapped AVFrames instead
of copying the actual data, greatly simplifying it in the process.

When two formats lists cannot be merged, a scale filter is
auto-inserted. However, when it comes to hardware map, we have to
manually add a hwmap filter to do the conversion. This patch introduces
an auto hwmap filter to do the hwmap conversion automatically and
modifies the negotiation structures,
The simplified parsing currently in `mov_write_ac3_tag` trusts the content
of the packets a bit too much (the AC-3 parser returns all data fed to it,
including any possible data before the start code), while the existing E-AC-3
logic does proper header validation by utilizing the (E-)AC-3 parser.
