9abbe8cc13 Use av_printf_format to check the usage of printf style functions 
This helps catching cases where the format string doesn't
match what is passed in, or injection bugs where user data
is passed in as format string.

67e7dc5404 rawdec: Fix decoding of QT WRAW files. 
From some tests it results that:
1. All of the AVI/MOV WRAW files need to be flipped.
2. MOV WRAW files need to use AVI color modes.
3. Assigning PAL8 mode by default to WRAW codec is not correct.

aa15e68721 Fix decoding of mpegts streams with h264 video that does *NOT* have b frames 
One of the causes of this bug is that the h264 parser defaults low_delay
to 1, but the h264 codec defaults low_delay to 0. Really Ugly.

After many hours of looking at this, I'm still not sure how has_b_frames
is *intended* to behave, but to me the implementation appears way more
complicated than it ought to be.

My patch relies on the encoder to set an optional field in the SPS. This
works for libx264 streams, but I'm not sure that all h264 encoders will
set it.
