Calculate the skip_coeff as part of the encode process, rather than
checking the eobs after the fact with another pass.

* changes:
  Removing unused switchable_interp_count[] field from VP9_COMP.
  Using clamp() function instead of the same raw code.

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.

Putting appropriate check to open_output_file() and close_output_file().
Before that the output file has been opened twice during two-pass encoding.

File type check inside ivf_read_frame() is not necessary (it is done
before this function get called).

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.
