The current code is a generalization of the earlier progressive MV
prediction code. This was supposed to predict MVs for both interlaced
and progressive pictures. But the interlaced MV prediction is buggy
and works mostly by luck.
This partially fixes interlaced MV prediction.

The codec uses all previous frames as reference frames, so they
certainly must be preserved and readable.

The return value ret isn't an error code that can be passed
to ERR_error_string().
This makes the error messages printed actually contain useful
information.

Changing the lowres value is risky because the user application may have a
local copy and not read back into it, or not undo some lowres dependant things.
A patch implementing this in ffplay is already on ffmpeg-dev, so this feature
should be back soon.
This reverts commit 125ea3ee06.

Actually check the return value of DecodeBegin, to make
sure that it has encountered no errors.

Remove the CODEC_CAP_LOSSLESS flag, as it doesn't make
any sense for a decoder to use it.
