Ari Koivula 3a80c7de74 Further optimize coefficient coding
Remove the need to count the coefficients by populating the significant
coefficient group map first and finding the last coefficient from the
last group afterward. The speedup is about 2% on ultrafast.

The previous version of this patch was reverted due to a bug, which
has now been fixed.

Ari Koivula b32965925e Revert "Further optimize coefficient coding"
This reverts commit 25462124f8.

That commit broke the bitstream. If it's not good enough to push on Friday
night, it's probably not good enough on Monday morning either.

Ari Koivula c94707e6e8 Fix bug with OWF+FME+deblocking
Increases the MV safety margin of OWF from 2 to 3 when deblocking
is used and 4 when both deblocking and FME are used.

Fractional pixel motion estimation can move the vector one more pixel
down causing checksum error. This fixes that error by increasing the
OWF safety margin and changes the interface, so that different margin
can be used when FME or deblocking are not in use.

Arttu Ylä-Outinen 43fc6ac419 Mark deblock functions static.
Marks the following functions static and removes them from filter.h
since they are not used outside the filter module.
- kvz_filter_deblock_luma
- kvz_filter_deblock_chroma
- kvz_filter_deblock_edge_luma
- kvz_filter_deblock_edge_chroma

Arttu Ylä-Outinen c93a190940 Refactor deblocking filter functions.
- Replace parameter depth in kvz_filter_deblock_edge_{luma,chroma} with
  length.
- Move checking whether an edge needs to be filtered from functions
  kvz_filter_deblock_edge_{luma,chroma} to functions
  kvz_filter_deblock_{cu,lcu}.
- Use pixel coordinates instead of 8-pixel block coordinates in
  kvz_filter_deblock_cu.
- Add comments.

These changes should make it easier to modify the deblocking filter to
handle SMP and AMP blocks.

Arttu Ylä-Outinen 95fb2ed9ed Fix unexpected behavior of --deblock option.
Giving a single number as an argument to --deblock option would enable
deblocking and set both beta and tc to that value. This commit changes
a single number argument to be interpreted as a boolean specifying
whether to enable deblocking or not. As a result, "--deblock 0" can be
now used to disable deblocking.

This fixes deblocking being enabled in all presets.
