adf8533cee vp9: Move consec_zero_mv from cyclic refresh to cpi struct. 
So it can be used even with aq-mode=3 not enabled.
Also cleans up some code in the places where its used.

No change in behavior.

cf7f00691f Change hybrid transform function argument from TXFM_2D_CFG* to int 
Unit test shows manually developed SSE4.1 code would performs ~30%
  better if TXFM_2D_CFG configuration is set in lower level. This
  change only updates function signature. There is no performance
  impact.

Removed this todo because of another todo which says none of this code
should exist. It should be integrated into the block by block encode
process as per the decoder.

9ca6b46cef vp9: Adjust gf period for high average Q and overshoot. 
For 1 pass vbr mode.
Increase the gf interval for case where average Q is close to
max and high overshoot is detected.

Small increase in overall avg_psnr/sssim metrics (~0.2/0.1%) for ytlive,
but improves the low-end (low bitrate) for several clips (less overshoot).

7aa95be980 Fix uninitialized blk_skip for VAR TX. 
x->blk_skip used to be uninitialized (leftover from encoding the
previous block), if cm->tx_mode != TX_MODE_SELECT (which is used with
higher --cpu-used or --rt options). This resulted in degraded coding
performance when using cm->tx_mode != TX_MODE_SELECT.

This fixes the VP10/EndToEndTestLarge.EndtoEndPSNRTest/40 unit test.

Also fixed an edge effect where encode_block in encodemb.c used the
formal width of the block (without cropping at the right edge), to
look up blk_skip, while select_tx_block in rdopt.c used the cropped
width to set blk_skip.
