If a parent mb is available but is intra coded, then parent_ref_mv is
invalid. Check that the parent is inter coded before trying to access
the parent_ref_mv. Previously the parent_ref_mv was being read from
an uninitialized stack allocation, causing potential OOB reads and
other undefined behavior.

Added a virtual function to handle PSNR packets.

Modified EncoderTest class to have separate member variables
for initialization time and per-frame.

The stats buffer needs to be reset between runs of the
encoder. I added a Reset() function to TwopassStatsStore
and called it at the beginning of each encode.

This enables us to run multiple encodes which was
previously not possible since there was no way to reset
the stats between runs.

Protect the call to {Initialize,Delete}CriticalSection() with an
Interlocked{Inc,Dec}rement() pair, rather than the previous static
initialization. This should play better with AppVerifier, and fix issue

The codec as it stood placed a keyframe one frame after a
real cut scene - and ignored datarate and other considerations.

TODO: Its possible that we should detect a keyframe and recode
the frame ( in certain circumstances) to improve quality.

Reset the cyclie refresh mode index in alloc_compressor_data().
This is needed to handle both cases of internal and
external spatial resizing.

Change-Id: I2697e12d45135eae2e8f0d45161811f24722312a

On an internal spatial resize, this mode index was not reset to 0,
and therefore could exceed dimensions of seg_map or cyclic_refresh_map.

Patch Set 1: gain familiarity with unit tests... added simple
4x4 subtract test
Patch Set 2: fixed mistakes, parameterized as suggested
Patch Set 3: randomized the source/predictor data

Add configure detection of the new x32 ABI as well as support in asm.

in order to make it easier to implement the frame-base multithreading.

Fixes some build issues for people building for win32 who have a
pthreads emulation layer installed.

This should avoid problems with blocks gettings high quality
improvement despite having recently moved:

Set the seg map to 0 for key frame.

In previous commit on cyclic refresh, the seg map for key frame
was not reset, and instead used the seg map from last frame.

-Increase the amount of mbs to be refreshed.
-Replace the delta qp with a fixed and reduced delta.
-Change to the mb update loop to try to always update same amount of mbs.

Change-Id: I93ac88002fd8dc677d2337f77998ff93f64e4ff9

Used mbc instead.

This change is necessary for the frame-based multithreading
implementation.
Since the postproc occurs in this call, vpxdec was modified to time around
vpx_codec_get_frame()
