Yunqing Wang c8773416fb Fix uninitialized read in postprocessing
This patch fixed WebRTC Issue 3020: "Uninit error at
vp8_mbpost_proc_down_xmm". The first 8 values in d were not initialized,
but was accessed. This patch fixed c code as well as mmx and sse2 code.

James Zern 805078a1bf build: convert rtcd.sh to perl
significantly speeds up file generation.

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.

Matthew Heaney dcab9896e8 Fix linker warnings for bilinear filters
The declaration of the bilinear filters specified an alignment clause
in the implementation file but not in the header.  This turned out
to be harmless, but it did cause linker warnings to be emitted when
building on Windows.

The (extern) declaration in the header was changed, to match the
declaration in the implementation.

Deb Mukherjee e378a89bd6 Support a constant quality mode in VP9
Adds a new end-usage option for constant quality encoding in vpx. This
first version implemented for VP9, encodes all regular inter frames
using the quality specified in the --cq-level= option, while encoding
all key frames and golden/altref frames at a quality better than that.

The current performance on derfraw300 is +0.910% up from bitrate control,
but achieved without multiple recode loops per frame.

The decision for qp for each altref/golden/key frame will be improved
in subsequent patches based on better use of stats from the first pass.
Further, the qp for regular inter frames may also be varied around the
provided cq-level.
