Adding a --(enable|disable)-webm-io flag to control WebM container input and
output support. For now, enabling WebM IO by default only when there is a C++
compiler. Doing so because eventually we will move WebM IO to libwebm and it
is built using C++.

The block size used for non-RD mode decision in FIXED_PARTITION
setting was uninitialized. This commit fixes it by setting block
size to be BLOCK_16X16.

Neon code unit test is failing now due to save/restore neon register
operations are not done inside this function, but outside of it. Disable
it now until VP8 neon code get cleaned up.

Adds a fast diamond search which is about 5% faster than FAST_HEX
with only a 0.1% drop in psnr when turned on for both speeds 5 and 7.
This search is turned on for speed 7.

Merge "Disable the neon version vpx_yv12_copy_y. For some dimensions, neon code ends up in a dead loop inside. This will fix the unit test failure in svc_test on ARM."

This commit allows the non-RD mode decision to skip mode RD modelling
check, if the motion vector associated with the current mode is
same as that of NEARESTMV mode. This makes speed -7 about 2% faster.
Previous change that converts cost metric from SAD to model based RD
value makes the codec 6% slower at speed -7.

The rate-distortion model in non-RD coding mode is only applied to
luma component. This commit removed a few redundant addition steps.
