The change can be temporarily reverted by setting ALLOW_128X32_BLOCKS
to 1 (for easy "is this better?" testing: we'll get rid of the option
once it's clear what we're doing).

Since this means we have to modify the "num_partition_types"
calculation in functions like read_partition, we move it into a helper
function called partition_cdf_length(). Doing this makes the bodies of
read_partition and write_partition somewhat simpler than they were.

The first stage of the selfguided filter is to generate box sums of
the input image (and its squares). This is done with a pair of
integral images, which are the same for both calls in
apply_selfguided_restoration.

This patch refactors things so that av1_selfguided_restoration
calculates both "flt" buffers, allowing it to reuse the integral
images that it calculated.

This doesn't have a big performance impact, and it's rather simpler
just having one version of everything.

This fixes some Valgrind errors caused by reads from x_by_xplus1 that
used tainted data as an address (see the comments in selfguided_sse4.c
for what's going on).

It also rewrites the algorithm to use an integral image approach
instead of the handwritten filters that the code was using. The end
result is roughly the same efficiency (I think that there's one more
memory load per group of pixels, but this seems not to be measurable)
and I've done some performance optimisation with perf too. Several
32-bit multiplications have been replaced by madd instructions which
do 16-bit multiplications and add adjacent lanes. This is equivalent
to a 32-bit multiplication when the 32-bit lanes contain numbers below
2^15, but runs significantly faster.

result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift
intended?)

Previous assumption on reduced_tx_set_used=0 led to many assertion
failures and prevented signalling reduced_tx_set_used equal to 1.

The code was assuming that an mi was always 4 samples wide and
high. For chroma planes with subsampling, this is wrong and the size
and position of the sb in the plane was over-estimated by a factor of
two. This meant that we sent all the coefficients in the top-left hand
quarter of the tile. Since the encoder and decoder made the same
mistake, this worked fine, but it's clearly not what we're supposed to
do!

In order to address hardware concerns regarding luma averaging,
this patch caps the maximum length of the sides of the luma
averaging area to 32.

This proposal was accepted by the hardware working group on
November 20th 2017.

- Reuse scan order
- Truncate to max eob of 32*32
- Quantization and entropy coding same as done for TX_32X32
- Reuse quantization matrices of TX_32X32

Compression performance is roughly neutral:
