#8850: SVQ3 (Sorenson 3) Codec Fails on Multi-Core Systems

-----------------------------------------+----------------------------------
When attempting to use MythVideo to play a MOV file containing SVQ3
encoded video, the internal player fails (on MythTV 0.22 fixes
mythfrontend crashes and on MythTV 0.23 mythfrontend returns to the video
selection screen). As far as I can tell, the problem is that the SVQ3
codec does not suppport multi-thread decoding (and exits with a return
value of -1) yet MythTV configures for multi-thread decoding when there
are multiple cores available anyway.
I have attached patches for MythTV 0.22 fixes, MythTV 0.23 fixes and
trunk. They force threading to 1 when the codec is SVQ3. This may not be
the best fix, but I did it because it works for me on my MythTV 0.23
system (I have tested it on MythTV 0.23 fixes not on MythTV 0.22 or MythTV
trunk).
