From now on if only one dimension is set we calculate the other based on
size/aspect of the shown content.

Improves "ffmpeg -i" output for raw dvbsub files.

djgpp 2.05 finally provides posix-compatible memalign, but it is broken,
so use malloc instead.

discussion: http://www.delorie.com/archives/browse.cgi?p=djgpp/2017/12/29/16:26:58

Also update fate test. Fixes #5258.

If the frames context creation fails then the command queue reference
need not exist when uninit is called.

Allow standalone compilation of the dvbsub and the dvbtxt demuxer.

Fixes ticket #7506.
