the goal of this change is to convert rtcd.sh to perl as directly as
possible to allow for simple comparison. future changes can make it more
perl-like.

This CL changes libvpx to call a function when a frame buffer
is needed for decode. Libvpx will call a release callback when
no other frames reference the frame buffer. This CL adds a
default implementation of the frame buffer callbacks. Currently
only VP9 is supported. A future CL will add support for
applications to supply their own frame buffer callbacks.

Change-Id: I599527ec85c577f3f5552831d79a693884fafb73

This fixes issue 667.

In the case where the frame was an odd number of pixels
wide or high, the border was being extended by one col
or row too far.

The calculation of color plane dimensions was modified
to use those already computed at the time the frame
buffer was allocated.

Also freed the temporary scaling buffer in vpxdec to
prevent a memory leak.

This is a short term optimization till we work out a decoder
implementation requiring no frame border extension.

Change-Id: I02d15bfde4d926b50a4e58b393d8c4062d1be70f

This is required because upon downscaling, if a motion vector points
partially into the UMV (e.g. all minus 1 of 64+7 pixels, i.e. 70),
then we can point up to 140 pixels into the larger-resolution (2x)
reference buffer UMV, which means the UMV for reference buffers in
downscaling needs to be 140 rounded up to the nearest multiple of 32,
i.e. 160.

Longer-term, we should probably handle the UMV differently by detecting
edge coverage on-the-fly and using a temporary buffer for edge extensions
instead of adding 160 pixels on all sides of the image (which means a
CIF image uses 3x its own area size for borders).

This is a mostly-working implementation of an extra channel in the
bitstream. Configure with --enable-alpha to test. Notable TODOs:

 - Add extra channel to all mismatch tests, PSNR, SSIM, etc
 - Configurable subsampling
 - Variable number of planes (currently always uses all 4)
 - Loop filtering
 - Per-plane lossless quantizer
 - ARNR support

This implementation just uses the same contents as the Y channel
for the A channel, due to lack of content and general pain in
playing back 4 channel content. A later patch will use the actual
alpha channel passed in from outside the codec.

Make framebuffer allocations according to the chroma subsamping
factors in use. A bit is placed in the raw part of the frame header for
each of the two subsampling factors. This will be moved in a future
commit to make them part of the TBD feature set bits, probably only set
on keyframes, etc.
