5307adadeb vp9: only call ff_get_format on stream format changes. 
In practice, this means we don't call it N times for N-threaded decoding.

2cbaa078d1 avcodec: use HAVE_THREADS header guards to silence -Wunused-function 
When compiled with --disable-pthreads, e.g
http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7,
a bunch of -Wunused-functions are reported due to missing header guards
around threading related functions.
This patch should silence such warnings.

a0d8a81075 vp9: switch min_tile_cols location so it shifts up instead of down. 
This fixes cases where the shifted number is 64, but we shifted non-
zero numbers away in the shift. The change makes behaviour consistent
with libvpx.

fd8b90f5f6 vp9: fix overflow in 8x8 topleft 32x32 idct ssse3 version. 
Also disable the mmx/iwht optimization when the bitexact flag is set.
With synthetically coded coefficients (i.e. these that lead to a
residual well outside the [-255,255] range), our optimizations will
overflow. It doesn't make sense to fix the overflows, since they can
only occur on synthetic input, not on real fwht-generated input. Thus,
add a bitexact flag that disables this optimization.

b18eac7ff2 vp9: change type of tile_size from unsigned to int64_t 
Otherwise the check 'tile_size < size' treats a negative size as
unsigned, causing the check to pass. This subsequently leads to
segmentation faults.

If we find a second non-sub8x8 motion vector for a non-first sub8x8
block, and the clamped value is identical to the first non-sub8x8

libvpx (probably accidentally) clears the bits if error_res is set,

(since it's local data), but it's behaviour we have to copy...
