This large function is solely used for the RDO search for
inter prediction mode. It would be helpful for readers if its name
tells that whole function is used for inter mode decision only.

In this case, calculating the shear parameters fails
with a divide-by-zero error. So disable the new filter
in this case.

We also temporarily remove the asserts blocking use
of the old filter with debugging enabled.

* Change the behaviour of search_wiener at borders to match
  the behaviour of the Wiener filter itself
* Reorder the calculation in compute_stats, saving ~5% of
  encode time at low bitrates (tested on bus_cif.y4m at 200kbps)

* Optimize the self-guided and domaintxfmrf filters
* Save 576KiB of buffers in the encoder and decoder
* Disable self-guided filter for videos whose width or
  height is < 5, in order to help simplify the filter.

This results in an overall 30-40% improvement in decoder
speed with loop-restoration enabled (depending on source
and bitate), with no effect on video quality, *except* for
videos with width or height < 5 pixels.

VS compiling for 32 bit targets does not support vector types in
structs as arguments, which makes the v256 type of the intrinsics hard
to support, so optimizations for this target are disabled.

Fix an intricacy due to interactions between cb4x4 and var-tx that
sets frame header away from tx_mode_select. This resolves a rare
enc/dec mismatch issue.

The bit accounting was broken when refactor portions of PVQ to use the
 aom_reader / aom_writer API because the daala_ec calls were using
 OD_ACCOUNTING instead of CONFIG_ACCOUNTING.
This fixes them so that bit accounting will still work with pvq while
 the full port to --enable-accounting is in review.

This commit reworks the transform block partition context update
to support cb4x4 mode in the recursive transform block partition.
It resolves the remaining enc/dec mismatch issue when both cb4x4
and var-tx are turned on.

Enables Wiener based loop restoration only for the UV
frames. The selfguided and domaintranform filters do not
work very well for UV components, hence they are disabled.
For each UV frame a single set of wiener parameters are
sent. They are applied tile-wise, but all tiles use the
same parameters.

BDRATE (Global PSNR) results:
-----------------------------
lowres: -1.266% (up from -0.666%, good improvement)
midres: -1.815% (up from -1.792%, tiny improvement)

Tiling on UV components will be explored subsequently.

The functions generic_encode() and generic_decode() code the lsb values
 as raw bits using the od_ec_enc_bits() and od_ec_dec_bits() functions.
These code bits in the reverse order as the aom_write_literal() and
 aom_read_literal() functions, so both the encoder and decoder must
 be changed at the same time.
This commit has no impact on metrics but is a bitstream change.
