use \li to separate the list items contained in conditionals. this
avoids the encode page becoming a sub-item of decode; likely a problem
in <1.8.3.
+ fix encoder conditional, spelling error
+ correct encode page name to match decode 'Encoding'

use \li to denote list items with \if.

fixes the following likely visible in <1.8.3:
usage.dox: warning: Invalid list item found
usage.dox: warning: End of list marker found without any preceding list items

This makes clear that for end-usage, only 0 is supported currently.

The commit updates the comments in vp8cx.h to make it clear which
codec support each of codec control functions.

Crash occured on very first key frame, because denoiser
temporal function was beng entered.

Updated denoiser unittest to set cpu_used from first frame,
and verified fix fixes the crash.

* changes:
  Added comment for vp9 only codec controls
  Rename a vp9 only control with vp9e prefix

Change-Id: I5c96b6a25f9df60da65b7af7c92a921b611746e3

Comments are updated to reflect that these controls apply to VP9 only,
thereby, to insure the document produced by doxygent to reflect the
same fact too.

Change-Id: Ic54c88ec066aa0ec4552d43dd4a7016e1f810f42

Also updated comments and doc to make it clear that the control is
supported in VP9 only.

This commit uses a 6-point 1-step refine motion search in the
integral projection based full pixel motion estimation, to replace
the current 9-point search.

It reduces runtime cost of speed -6 on some noisy clips, e.g.,
dark720p single thread
33314 b/f, 40.076 dB, 18231 ms ->
33307 b/f, 40.067 dB, 17768 ms

The compression performance for rtc set remains unchanged.

This commit changes to use single loop to evaluate all inter modes.
There is no impact on compression quality and speed, but allow future
experiment with the order of modes evaluated.

Change-Id: I71696ce1014cbe127e25e98710d835987f5ecc09

Added a skip_dc check. If skip_dc = 1, we could eliminate calling
of vp9_model_rd_from_var_lapndz(). This gave slight PSNR & SSIM
gain(<0.1%), and no speed change.

This fixes all test vector failures

Re-arrange the multiplication and right shift operations to avoid
integer overflow in choose_partitioning.
