This moves up to the main the decision of which coding path to use,
aligning the decoder's logic on the encoder's logic.

the tile boundary info flag was updated for each mi data structure
which starts from cm->mi. there is the second level buffer which
contains the pointer to the mi structure. it starts at
cm->mi_grid_visible. for every coded block, pointer in the second level
buffer only points to the top left mi structure of that particular coded
block. in order to get the correct boundary info for each mi. we have to
access the mi structure from cm->mi instead of cm->mi_grid_visible.
this change doesn't impact the result, it only cleans up the logic.

Before:
-------
accu_error was always <= 0:
- It was initialized to zero, and
- Became more and more negative through the iterations.

This meant that RDOPT() macro usage on accu_error was causing left shift
of negative value.

Now:
----
- accu_error is initialized to a large positive value.
- It becomes smaller on every iteration but remains >= always.

This is functionally equivalent: verified that there's no change in
output due to this patch.

Fix a bug where the encoder sets reference_mode =
COMPOUND_REFERENCE even if the frame contains some
4x4 blocks (but no larger blocks) that are single
reference. This occurs only in corner cases,
typically for very small frame sizes (e.g. 16x8).

Adds "superres-mode" and "superres-numerator" arguments to configure
superres scaling.

There are only two modes right now: SUPERRES_FIXED and SUPERRES_DYNAMIC.
0 sets the fixed mode and 1 sets the dynamic mode.

For the fixed mode superres will scale to the provided numerator where
possible. The cumulative scale change over resizing and superres is
limited to 1/2, so it may have to back off.

For the dynamic mode, the provided numerator will be used as the initial
numerator. Asides from that it's just random for now.

There were several places where loop_restoration used the encoded width
and height while superres was active. This patch changes it to use the
upscaled width and height, since loop_restoration is supposed to occur
after superres has done its upscaling.

Daala-dist replaces the luma distortion of sub8x8 partitions with
its own distortion thus requires to split the luma distortion only.
Doing so, there has been a bug that INT_MAX64 value comes
when the sub8x8 parition is skipped. This happened because the existing
code does not initialize the rd_stats_y or tmp_rd_stats_y, i.e. rd_stat struct
for luma only in several places.

This patch implements the post-encode and post-decode upscaling for the
frame superresolution experiment to work.

Upscaling happens after cdef and before loop restoration.

days, to be brought back later when the resize and superres tools
are stable.
