OptionDef.u is only an offset (i.e. its off member) iff OPT_FLAG_OFFSET
is true. Otherwise, the pointer arithmetic can be undefined behaviour.
UBSan warns about this (on 32bit arches):
src/fftools/ffmpeg_opt.c:102:15: runtime error: pointer index expression with
base 0xffa4db10 overflowed to 0x560

HAVE_FAST_UNALIGNED being true does not imply that
one can simply read from any pointer via *(long*).
It is undefined behaviour in case the pointer is not
sufficiently aligned; and even if it is, it is (likely)
a violation of the effective-type rules. Fix both
of these by using the appropriate AV_[
It is accessed via AV_RN64() in ff_simple_idct_put_int32_10bit().
Should fix the UBSan failures in the mpeg4-simple-studio-profile
test here:

h_subpel_filters_inner[i] and h_subpel_filters_outer[i / 2]
belong together and the former allows the range 0..6,
so the latter needs to support 0..3. But it has only three
elements. Add another one.
The value for the last element has been guesstimated
from subpel_filters in libavcodec/vp8dsp.c.

Check for zeros equal to the total samples early, because in
that case we would already be leaving the first few frames out.
Fixes trac ticket #10692
