* changes:
  usage.dox: fix encoder/decoder subpage list indent
  usage.dox: fix doxygen warnings in 1.8.x

Move the scaling factor outside column projection. This avoids
repeated calculation of the same scaling factor. Profiling shows
that the percentage of vp9_int_pro_col_sse2 of overall cycles
goes from 2.29% down to 1.88%.

1. remove duplicate initialization to mbmi->interp_filter.
2. move mv clamping into ref_frame loop instead of mode checking loop.
3. move the check if last frame is same as golden frame earlier to
avoid initialization of Golden reference related variables.

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

The compression performance of speed -5 is on average 12.6% better
than speed -6. At lower bit-rates, the gains are typically 20% or
more. For 2-thread encoding, the speed -5 takes about 1.6x time of
speed -6.

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.
