produce multiple AVFrame variants after a minor lib update

Its possible to implement this with a few lines less code but it then
would flip the order of the list and require registration of external
codecs to be done first, also it could break user applications due to
this. Thus to maintain ABI this slighty more complex solution is
used.

After adding colorspace support to xine-lib, I insist in proper
settings within media files at least when they do not follow
that implicit SD/HD routine.

Currently only dc-only and full 16x16. Other subforms will follow in the
near future. Total decoding time of ped1080p.webm goes from 9.7 to 9.3
seconds. DC-only goes from 957 -> 131 cycles, and the full IDCT goes
from ~4050 to ~745 cycles.

Tables are always allocated now with sufficient space for either progressive
or interlaced content. The alternative would be to detect a change
and reallocate.

Given ETSI EN 300 743 V1.3.1 (2006-11), 7.2.1 Display definition segment
display window parameters are given in this order XMin, XMax, YMin, YMax
if display_window_flag is set, but here this is not the case.
As a consequence the DVB subtitles are not displayed upon some videos.
