vp8: change mv_{min,max}.{x,y} type to int

If one of the dimensions is larger than 8176, s->mb_width or
s->mb_height is larger than 511, leading to an int16_t overflow of
s->mv_max.{x,y}. This then causes av_clip to be called with amin > amax.

Changing the type to int avoids the overflow and has no negative
effect, because s->mv_max is only used in clamp_mv for clipping.
Since mv_max.{x,y} is positive and mv_min.{x,y} negative, av_clip can't
increase the absolute value. The input to av_clip is an int16_t, and
thus the output fits into int16_t as well.

For additional safety, s->mv_{min,max}.{x,y} are clipped to int16_t range
before use.

Thus remember where the last resync happened and don't try to resync
before that.

This can't be done locally in nut_read_packet, because this wouldn't
prevent infinite resync loops, where after the resync a packet is

avcodec/flacenc: Fix Invalid Rice order

Fixes ticket #4628.

The problem arose, in the sample file at least, in the last block where the
minimum and maximum Rice partition orders were both 0. In that case, and any
other where pmax == pmin, the original UINT32_MAX placeholder value for
bits[opt_porder] was getting overwritten before the comparison to check if the
current partition order is a new optimal, so the correct partition order and
RiceContext params were not being set.
