MJPEG Tools Svn

Add uncompressed 4:4:4 (v308) support, not overly useful since probably nothing
except FinalCutPro will want it.

Remove debug logging statement.

add y4mtoqt for creating 2vuy (422) Quicktime files with audio track.

Complete the relocation of 10 programs in lavtools/ to the new y4mutils/

Uncluttering lavtools (in preparation for adding several more utilities) by
relocation to the new y4mutils directory

OK, this is a big quality improvement... The image quality now is better
(by far!) than by any other deinterlacer (motion-compensating or not) I
know. I should disable the lowpass-filter in the postprocessing-stage,
too (This then gives an image which nearly does not show any loss in
sharpness...)

Bugs: first two fields garbage. Need to interpolate spatialy.
not as fast as it could be...
does not compile cleanly

further quality improvement

0 is a valid option and does the expected thing for -t (some or all of the
temporal filtering can be disabled). Also, document that 0 works for -g
by disabling some or all of the gaussian blur processing.

gcc complained thusly:
imageplanes.cc:82:2: warning: no newline at end of file

so add a \n :)

Unused variable dotptr.
