Jan Ekström 5de64bb34d utvideoenc: Add support for the new BT.709 FourCCs for YCbCr 
With cli usage the decoder might have not set the colorspace during
encoder init, manual colorspace override might be needed in such
cases.

s->prob.coef is a [4][2][2][6][6][11] array.

Anton Khirnov e0ab5078a7 lavc: do not force the emu edge flag 
The default get_buffer2() implementation (and possibly some
user ones) does not allocate edges when this flag is set, which may
expose bugs in some decoders. Until the 10 release is out, it is safer
to remove this part.
