MJPEG Tools Svn

Fixed some serious errors in the 3:2 pulldown code in mpeg2enc and mplex.
Seems to work now. Hurray for video rental places with region-1 DVD's.

Thanks to Shawn for his upgraded lav2divx and yuv2divx utilities

Doh!

o y4m_parse_ratio() now available in library
o fixed interlace description strings
o a bit of const correctness

o Changed SDL overlay initialization to use "YV12" format instead of "IYUV".
...Identical, except that Cb and Cr are swapped (and so I swapped the writes
to the display buffers elsewhere in the code). IYUV is an alias for I420;
unfortunately, for my mga driver, Xv only knows about "I420", but SDL only
knows about "IYUV", so hardware overlays never got used.
YV12 seems pretty universally supported by everyone.
o Fixed yuvplay to write to/display overlay properly.

Fixed bug whereby individual frames may be allocated more bits than the
video decoder's buffer size!

Added -config script for for convenient auto*-ing
of apps that use mjpegtools libs and include files.

use new yuv4mpeg

Another patch, thanks Francis
