Various cleanups and refactoring.
Removes feedback of active worst qaulity and uses last_q
instead to make the interface cleaner. Active worst quality
is now decided only once for a frame being coded in the
beginning based on last_q and other stats. Also, adds other
cleaups on last_q to store also the last_q for altref frames,
and reduces the altref interval a little.
The output does change a little.

Properly handle the rd_filter_cache update, when early termination
or skip prediction filter type check is triggered.

This commit enables an adaptive prediction filter type selection
for sub8x8 block sizes. In speed 1, it re-uses the filter type of
collocated 8x8 block if it is tested in the rate-distortion optimization
loop, for the sub8x8 blocks. Otherwise, it runs the normal test
over all the three filter types. In speed 2, it re-uses the 8x8
block's prediction filter type, if available. Otherwise, force it
to be EIGHTTAP.
Compression and speed performance wise:
speed 1
derf -0.266%
yt -0.138%
bus at 2000 kbps: 33766ms -> 30451ms (10% speed-up)
football at 600 kbps: 48173ms -> 43786ms (9% speed-up)
speed 2
derf -0.026%
yt +0.134%
bus at 2000 kbps: 18973ms -> 17698ms (6% speed-up)

This commit constrains the maximal motion search range for sub8x8
blocks to be [-1023, 1023], in the unit of full pixel.

Both single frame and compound inter motion search run with luma
component only. Hence removing the block size mapping therein.

In the decoder we don't need to save eobs, we can pass eob as an argument.
That's why removing eob arrays from VP9Decompressor and TileWorkerData,
and moving eob pointer from macroblockd_plane to macroblock_plane.

Its last remaining caller can be passed its results directly without any
additional work. Also, it's not non-4:2:0 safe.

This commit fixes the use of uv_intra_estimate by properly restoring
the mode_info struct required by rd_pick_intra_sbuv_mode.

We only need qcoeff buffers in the encoder. Reducing TileWorkerData struct
and VP9Decompressor struct sizes by 24K.
