This commit allows vpxenc to properly set the effective motion
vector values in the mode_info struct for inferred motion vector
modes. It resolves an enc/dec mismatch issue due to the mode info
struct loaded from external file has conflict effective motion
vector and inferred prediction mode.

This commit converts the sub8x8 block mode info from external file
into proper format that conforms the bit-stream definitions. It
resolves an enc/dec mismatch issue in sub8x8 block coding used in
the inter frames.

This commit refines the configuration interface for encoding
process based on external mode info. It allows the vpxenc to read
the external file name from command line, and to produce warning
message when necessary.

This commit relaxes the encoding mode constraints on key frame
coding. It improves the key frame coding performance in speed 5 and
up.

This commit allows the vpxenc to check if the motion vectors read
from external file comply the frame header. If the frame is using
lower precision, the codec will convert the non-conformable motion
vectors into corresponding level.
This fixes another outstanding enc/dec mismatch issue due to the
mode_info values provided by external file not complying the
bit-stream definitions.

This commit forces a transform size check to handle the case where
the provided transform size is larger than the block size. In such
cases, it will convert the transform size to be the maximally
allowed value according to the block size.

This commit makes the key frame coding to use the normal vpxenc
coding route. The encoding process based on mode_info read from
external file now starts from the first inter frame.

The decoder read/write access to the mode_info array was for the
purpose of creating a conformable coding mode decisions and hence
validating the encoding process based on exteranl mode_info
array. This commit makes a flag to disable all such potential access.

This commit enables the encoder to convert the mode information
read from external file into effective VP9 coding decisions. Further
optimization for compression performance can be applied therein.

This commit adds an optional function to print out the mode_info
loaded from external file for debug purpose. It can be turned on
by setting PRINT_MODE_INFO_LOAD 1.

Allow the encoder to use fixed quantization step size. Note that
this effectively breaks the internal rate control scheme and
can cause substantial compression performance.

This commit allows the encoder to handle cases where the encoder
is forced to use an arbitrary prediction filter type.

This commit enables vpxenc to encode and write out bit-stream from
coding information provided by external mode_info array file. It
currently assumes single reference frame and 8-tap switchable
prediction filters at frame header level.
Tested using the mode_info array dumped at VP9 decoder into the
external file, where the bit-stream was generated by VP9 encoder
at speed -6. The coding statics remain the same.
Note that the compression performance will be affected quite a lot
in the two pass coding setting, where at this point the rate
control scheme can not be updated properly without statistics
gathered during rate distortion optimization search.

This commit allows the vp9 decoder to dump the decoded mode_info
array, per 64x64, into external file, which serves as conformable
test vector for transcoding encoder. The mode_info of 8x8 block
inside a 64x64 block is aligned in raster order.

In non frame-parallel decoding, this works the same way as
current decoding scheme. Every time after decoder finish
decoding a frame, it will swap the current mode info pointer
and previous mode info pointer if the decoded frame needs
to be shown. Both mode info pointer and previous mode info
pointer are from mode info arrays.
In frame-parallel decoding, this will become more complicated
as current frame's mode info pointer will be shared with next
frame as previous mode info pointer. But when one decoder
thread finishes decoding one frame and starts to work on next
available frame, it needs to retain the decoded frame's mode
info pointers until next frame finishes decoding. The mode info
index will serve this purpose. The decoder will use different
buffer in the mode info arrays and use the other buffer to save
previous decoded frame’s mode info.

In non-rd real-time mode, choosing smaller transform size in
encoding gives better video quality and good speed gain than
choosing larger transform size. This patch set tx size search
method to ALLOW_8X8, which is better than using 4x4 or other
larger sizes.
Borg tests on rtc set at speed 6 showed significant gain on quality.
PSNR gain: 11.034% and SSIM gain: 15.466%.
The speed gain is 5% - 12% for <720p clips, and 2% - 7% for
720p clips.

Use of stack frame variable "fps" beyond the lifetime of the function.
fps is sent as a paremeter to output_stats and stored in the
packet holding this encoded frame. This has scope beyond the
lifetime of the calling function.
