moving eob token counter increment.

E.g. disable vertical partioning for 4:2:2. Until we come up with something
better to do with the chroma block size, this prevents an assert error.

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.

Fixes an inadvertant change made in a previous patch while doing
some experiments.

Considering a horizontal edge, if mask_16x16 is 1 for an even-
indexed 8x8 block, then mask_16x16 is 1 for next 8x8 block in
same row. Similiar to a verticle edge, if mask_16x16 is 1 for
an even-rowed 8x8 block, then mask_16x16 is 1 for the 8x8 block
right below it in next raw. Based on that, the mask_16x16 checking
can be simplified to save cycles. The corresponding 8-pixel
vp9_mb_lpf_horizontal_edge code can also be removed.
