Optionaly filter 8x8 skip blocks, but still leave superblocks that are
completely skipped unchanged.  Use one bit in the dering level to
signal replacing the signal for dering damping.

This works better with cb4x4 that now is enabled by default.

When ext-refs is on, the encoding of HD videos, e.g. 1080p sequences
will cause the failure to allocate up-sampled frame buffers. This CL
temporarily turn off the use of upsampled references when ext-refs is
on for any video resolution larger than 720 in either dimension. A
more effective scheme for up-sampled referencing should be later
considered.

With the fix, the AWCY performance gains of ext-refs, vs baseline are:

PSNR Y
Average -2.55%
1080p   -2.81%
360p    -2.38%
720p    -3.10%

This reduces the multiplier width of daala_ec from 16x15->31 to
8x15->23, which reduces hardware latency by an estimated 20% (and
area for this module by an estimated 40%).

These are the smallest logical changes required to achieve this,
but the approach will be optimized significantly in subsequent
commits.

allow_txk_type doesn't contains all the logic of using pre
assigned tx_type or doing the tx_type search.
Here we use get_tx_type to avoid redundant tx_type search.

This was broken by commit 1238137c.

When calling the generic coder with a max, it truncates the CDF, but
then tries to encode/decode with the Q15 entropy coder functions
with built-in adaptation. That causes assertion failures, because the
total probability isn't 32768.

We could fix it by re-scaling the CDF, and then doing adaptation
assuming there was no max, but that requires several special-case
code paths.

Instead, since non-robust streams were the only thing that still
required calling the generic coder with a max, and since the gain
from them is very small (and they require doing more DSP just to be
able to parse the stream), we simply remove the option and force
the use of robust streams all the time.

With robust streams enabled, encoder output should not change, and
all streams should remain decodable without decoder changes.

Thanks to Nathan Egge for reporting the problem.

1) Check if tx_type is valid in get_tx_type

2) Remove scan_order from rdcost_block_args
When lv_map is on, scan_order depends on tx_type but tx_type is
not decided before entering block_rd_txfm yet. Therefore
assigning a scan_order into rdcost_block_args and then passing it
into block_rd_txfm will cause error.

3) Pass correct index into intra_mode_to_tx_type_context in
get_tx_type

This CL doesn't affect baseline/supertx's stats.

The tx_type becomes dummy when lv_map is on. The tx_type search
will be performed in av1_search_txk_type() and the results will be
stored in txk_type[]

In choose_tx_size_type_from_rd, we use best_txk_type[] to record
the best search result within different tx_size.
