ARNR filtering is now forced to be centered on the ARF
frame and the other two options have been removed.
The other modes of constructing the ARNR frame were
not used and there does not seem to be any good
reason to maintain them.
This is purely an encoder-side change.

The end_useage parameter is confusingly named since it
now actually defines the rate control method used.

1. We didn't scale source image in lower layers so that
the stats are incorrect.
2. We didn't extend borders for re-constructed image.

Delete code relating to the old VP8_TUNE_SSIM flag
as this code does not currently work and is largely made
redundant in VP9 by the various AQ modes.

Remove duplicate rd_thresh code introduced when vp9_rd_pick_inter_mode_sub8x8()
was forked from vp9_rd_pick_inter_mode_sb().

Added command line flags "resize-width" & "resize-height"
to allow the user to specify the frame size to encode at.
These two flags are ignored if the "resize-allowed" switch
is not set to 1.
All frames in the clip are then encoded at this size, which
must be smaller than the raw frame size.

Calculate the difference variance between last source frame and
current source frame. The variance is calculated at 16x16 block
level. The variances are compared to several thresholds to decide
final partition sizes.
An adaptive strategy is implemented to decide using
SOURCE_VAR_BASED_PARTITION or FIXED_PARTITION based on motions
in the video. The switching test is done once every
search_type_check_frequency frames.
The selection of source_var_thresh needs to be investigated
further later.
RTC set Borg test showed 0.424% overall psnr gain, and 0.357%
ssim gain. For clips with large enough static area, the
encoding speedup is around 2% to 15%.

Adds some high-level hooks for profile 2 before further
progress on the implementation.
According to the definitiion in this patch:
1. Profile 2 only supports 10 or 12 bit color but not 8
2. Profile 2 supports all color sampling modes: 444, 422 and 420,
and alpha plane.
3. Profile 3 is currently undefined.
Please consider the definition carefully and suggest modifications
to the definition as needed.

The new tolerance is a little higher than before (especially
for kf/gf/arf) so this change gives an encode speed up
for some clips up for speeds 0-2.

While encoding a frame, its last frame source can be used to give
acurate motion information. This patch prevents last frame to be
overwritten so that it is available during current frame encoding.
The last source is scaled when it is necessary. cpi->Last_Source
points to the last source frame.

This commit added a speed feature to make the logic of calculating
skip_recode on a block level more explicit. This also enable the
feature to be enabled at speed 5 where the previous logic is too
conservative, help gain back the lost speed for --rt(-5).
