Fixes playback with WMP 9 for files with large (rawvideo) frames
as explained in ticket #2145.

Fixes ticket #2818.

The encoder uses almost none of the mpegvideo infrastructure, only some
fields from MpegEncContext.

The FATE results change because now an all-zero quant matrix is written
into the file. Since it is not used for anything for ljpeg, this should
not be a problem.

This may improve compatibility of lgpegs generated by libavcodec
also encoded ljpegs become slightly smaller
