Adds an arbitrary-size resize library for use in scaling of input
frames in a non-normative manner in the vp9 encoder. The method
used is as follows:
Downsampling - Uses a 8 tap filter for factor of 2 decimation upto
a size just higher than the desired size. Then interpolates pixels
at a precision of 1/32 pel using a set of 8-tap filters.
Upsampling - Interpolates pixels at a precision of 1/32 pel using
a set of 8-tap filters.
There is no assembly optimization yet.

Encoder's boarder is still 160, while decoder's boarder will be 32.
With on demand and separate boarder buffer for boarder extension.
The decoder's boarder does not need to to 160 anymore.

This commit explicitly enforces the effective motion vector range
in the motion search stage. The range needs to be the intersection
of UMV border, effective absolute motion vector value range, and
the target search area.

The affect on quality was minimal. Less than .1%, various sets
yt ( +.15%), derf (-.1%), hd ( -.1% ), std hd(-.15%)...
The affect on speed of encode at speed -5 was substantial ( ~3% ).

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

Handle the non-420 case and set uv_width.
This is needed to get the correct colorspace information out of
vp9e_get_preview().

This commit setups a test framework for real-time coding. It enables
a light motion search for non-RD mode decision purpose.

Calculate the skip_coeff as part of the encode process, rather than
checking the eobs after the fact with another pass.
