When showing a previously decoded frame, we need to
explicitly set the show_frame flag.
For the current frame being decoded this flag is
explicitly set in the frame header.
This should fix WebM Issue 696:

Fixes assert that fails occasionally on small values of
max-key frame intervals. Also, adds a small change on
updating frames_to_key for frame drops.

There are three contributors to the definition of how the
display size is set:
(1) display width/height set in the container.
(2) display size (optional in the frame header)
(3) decoded frame size (from the frame header)
This patch modifies the way that vpxdec defines the display
size to give preference to these three criteria in the order
given above. If the container sets a non-zero size, it is
used, otherwise the display size specified in the first
decoded frame is used (if specified), with the raw
decoded frame size of the first frame used as a last resort.
The display size set in frames other than the first is
always ignored in this implementation.

Reference frame masking helped good quality mode to gain about 5% in
encoding speed, this commit enable it for rt mode to gain the speed
improvement.
In addition, this commit move the speed feature setup to a separate
function.

To reduce pulsing we now allow an arf just before forced key frames
and at the end of a clip or section (which may be stitched to
another clip or section). However, this does not make sense for
key frames arising from real scene cuts.
Change from original patch reflects other recent changes in regard
to alignment of gf/arf and kf groups.

Introducing calc_psnr() which calculates psnr between two yv12 buffers.
Previously we incorrectly used width/height instead of
crop_width/crop_height to calculate number of samples -- fixed.
