Slight improvement in midres and hdres sets of 0.02% and 0.0.9%
respectively.
This is also a better design anyways.

* 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)

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.

* Remove some unused variables
* Reduce need for casts by typing intermediate buffers appropriately
* Avoid copying data which is never modified; use the original data
instead.
* Reduce number of intermediate buffers required, saving allocations
of 576KiB in the decoder and ~1MiB in the encoder
No effect on performance

This commit moves a number of large buffers from stack to heap to fix
crashes due to stack overflow.

The main objective is to reduce computational complexity.
The domain transform filter has an effect of edge preserving smoothing
at a lower computational cost than the bilateral filter, and can be
readily paralelized.
A little drop in coding efficiency about 0.06% for lowres, 0.16% for
midres.

This filter is meant to replace the bilateral filter,
but is currently added in addition to the bilateral filter
for testing.
Change-Id: Ia529701e69833d47c11b3367d5bf804eb8498079
Includes a major refactoring/enhancement to support
tile-adaptive switchable restoration. The framework can be
readily extended to add more restoration schemes in the
future. Also includes various cleanups and fixes.
Specifically the framework allows restoration to be conducted
on tiles such that each tile can be either left unrestored, or
use bilateral or wiener filtering.
There is a modest improvemnt in coding efficiency (0.1 - 0.2%).
Further enhancements will be added subsequently to improve coding
efficiency and complexity.
