Modified the thresholds of deciding whether or not to skip
the transforms in model_rd_for_sb_y(). Used zbin[] instead
of dequant[] to be more precise. Also, modified the checking
coditions.

Rtc set borg test results (at speed 6) showed:
average PSNR gain: 0.138%, overall PSNR gain: 0.158%,
and SSIM gain: 0.177%.

The data rate test was modified slightly as suggested by
Marco.

using this to control reallocation would miss a change if the function
were not called for every frame.

This commit prevent the encoder to update last_frame_type when a frame
is dropped in the encoder. Prior to this fix, if there is a dropped
frame immediatedly after a key frame, decoder would have the value of
last_frame_type as key frame, different from encoder as the dropped
frame in encoder would have updated the value to an inter frame. This
leads to different probability update in encoder and decoder, thereby
encoder/decoder mismatch.

This fixes issue #941

Replaced a divide by 9 with 8, so some very small difference,
but otherwise no change in behavior.

Simple skin detection, from vp8; works reasonable on most of the
RTC clips, but could miss sometimes.

Added debug flag to write out skin map over source input.

This commit allows the encoder to properly account for the mode
cost in sub8x8 non-RD mode decision.

This commit adds a heuristic rate cost of reference frame to the
non-RD mode decision. It improves the compression performance of
speed -6 by 0.31% and speed -5 by 0.69%.

MODE_INFO struct was modified, and vp9_print_modes_and_motion_vectors()

this function works again for debug usage.

This is to avoid redo the same calculation repeatly, and also allow
