avfilter/vf_mpdecimate: debug logging of threshold stats

It's often really helpful to know why a frame wasn't decimated (lo or
hi), and how much you exceeded the threshold by, if you're trying to
tweak the thresholds to get what you want.

mpdecimate already prints a line per input frame with -v debug, this
just makes it longer.

mov: always check avio_read return value

If avio_read fails, the buffer can contain uninitialized data.

This fixes 'Conditional jump or move depends on uninitialised value(s)'
valgrind warnings, and addresses a few memleaks.
