This commit added a logic to prevent the inter_filter type from being
changed if the default interp_filter mode is not switchable. Also, it
sets the default interp_filter to BILINEAR at very and super fast rtc
encoding modes

--rt --cpu-used=-5 uses the progressive rtc mode

In this new mode, the size range is strictly determined by the min
and max partition size in neighborhood blocks.

Niklas720 encoding time at cpu-used -5 goes from 56250ms to 50676ms,
a 10% reduction.

This patch only works if the video is a width and height that are both
a multiple of 32..   It sets every partition to 16x16, and does INTRADC
only on the first frame and ZEROMV on every other frame.   It always does
does the largest possible transform, and loop filter level is set to 4.

Was ~20% faster than speed -5 of vp8

Now 20% slower but adds motion search ( every block ), nearest, near
and zeromv

The SVC test was changed because - while this realtime mode produces
bad quality albeit quickly, it isn't obeying all the rules it should
about which frames are available.

Reading second motion vector only when it has a second ref_frame

This commit deprecates the use of best_mv from encoding and bit-stream
writing stages. It hence removes the definition from MACROBLOCKD.

This commit allows encoder to compare the SAD cost associated with
the best motion vector predictor, per frame. If one reference frame
has this cost more than 4 times of the best SAD cost given by other
reference frames, skip NEARESTMV, NEARMV, ZEROMV mode check of this
reference frame.

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.

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.
