f927c5b753 vorbisdemux: Check private context in theoras gtopts.
This prevents a null ptr dereference.
It could be checked differently but this way it should
be possible to return some data.

ffa28da180 Support dropping audio dts/pts via -async -1.
Allows working around issue #605.
Note: as a side effect this fixes that -vsync drop
as far as I could tell would not drop pts/dts values
when duplicating frames or when flushing encoder delay.
