Yunqing Wang 153eec46e0 Align image buffer in multiple-resolution encoder 
Aligned the image buffer and stride to 32 bytes. This enables
calling of optimized scaler function in libyuv, and improves
the performance.

Tested libyuv scaler(x86 optimization) on Linux and Windows,
including: Linux 32/64bit, visual studio 32/64bit, Cygwin, and
MinGW32.

Also, fixed a wrong pointer in vpx_codec_encode().

Description:
libyuv is an open source project that includes YUV conversion and scaling
functionality.

The optimized scaler in libyuv is used in multiple resolution encoder example,
which down-samples the original input video (f.g. 1280x720) a number of times
in order to encode multiple resolution bit streams.

Local Modifications:
Modified the original scaler code from C++ to C to fit in our current build
system. This is a temporal solution, and will be improved later.
