This make do_video_out() and do_audio_out() consistent. Also simplifies
callers.

This simplifies a bit the #ifdefery.

This avoid a forward declaration.

This will allow some simplifications in transcode_video().

input_video_filter and output_video_filter can't be NULL at this point.
If they are, the current code would likely crash anyway (since
filtered_frame would be NULL and sent to do_video_out().

Fixes part of ticket #989.

in , else (1) { if (!1) } the if conditional will never evaluate to be true.
So as making the check useless.

The added tests are limited to the case where timestamp discontinuities
are not allowed. The default is 30 hours which is arbitrarily picked and
quite conservative.
This prevents a out of memory condition due to duplicating a frame
millions of times.
