81fd890773 Linearize extrabits writing. 
The decoder is already linear so changing these tables would just create
a mismatch.

4e4d3a075b Avoid unnecessary reencode in choose_largest_tx_size 
This change is similar to the one done for choose_tx_size_from_rd in
daf841b4a10ece1b6831300d79f271d00f9d027b

It gives a 4% speed-up on bus_cif.y4m with the following settings:
--cpu-used=4 -p 1 --end-usage=q --cq-level=40 --tile-columns=0 --tile-rows=0

9d07888350 Fix to make intra_only frames decodable out of order 
last_frame_type is not well defined for intra_only frames
if we are decoding them out of order.
This change removes a dependency on last_frame_type for these frames.

0b325978d7 Palette: Generate encodings automatically from tree. 
Ran some manual sanity checks:
- Verified that the automatically generated encodings match the
  hand-written encodings before the patch.
- Verified that the encoded bitstream before/after this patch is
  identical.

7f76d4763d Prevent potential token buffer overflow in format 444 
For a 16x16 pixel block, one needs to allocate 16x16 coefficient
tokens, plus up to 16 eob tokens, per plane. This commit increases
the token allocation size to cover the case where all the transform
blocks are of size 4x4 in format 444.

d7d78c83e5 Fix a bug when combining new-quant + supertx 
Previously, we assumed that av1_init_plane_quantizers is always called with
segment_id == xd->mi[0]->mbmi.segment_id (and use the latter to derive the value
of 'qindex' to use in the quantizer). But this is no longer true when supertx
is enabled. This patch instead remembers the value of 'qindex' derived from
the latest call to av1_init_plane_quantizers and uses that directly.
