MJPEG Tools Svn

Missing emms() spotted by Stephen Beahm - thanks!

Couple missing '-' to turn multithread into multi-thread (so it matches the
mpeg2enc program usage).

Fix obscure threading issue due to the last frame being read
while the corresponding StreamState is being set.

By popular demand (well, ok - I got one request to add it ;)) a simple
histogram program for YUV4MPEG2 streams is added. It's a simple program
created years ago to spot colorcast problems.

Fix invalid memory access

it is slower, it is not yet ready for everyone, but it does remove noise
a lot better ...

Control it's behavior with (spatial) -Y [n] -U [n] -V [n] and (temporal) with
-y [n] -u [n] -v [n]
