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.

This new coding tool is targeted to complete following two tasks:
(1) Remove the inter mode NEWFROMNEARMV;
(2) Add new inter coding modes that provide compound prediction but
    using single reference frame - initially NEAREST_NEARMV from
    single reference.

encoder and decoder, so the files have been moved into av1/common.

The SSE3 convolve functions do not work when scaling is involved. If
either x_step_q4 or y_step_q4 is not 16 scaling will occur and an assert
fails.

This patch creates a C version of av1_convolve, av1_convolve_c. This
function in turn calls all C versions of what av1_convolve calls. New C
versions of these called functions have been created where needed and
the same for the functions they call. This means that when scaling is
enabled no asserts fail. av1_convolve_c is called instead of
av1_convolve when x_step_q4 or y_step_q4 is not 16.

1) block_raster_idx is actually raster order only when tx_size
is TX_4x8.
It's very specific, so we should put it near to the place it's
actually used.

2) Sync the meaning of block_idx on encoder/decoder sides

multi-thread loop filter is built on certain assumptions that would
require changes in many table contents. Temporarily disable the
