This is required in order to build libvpx on OS X Mavericks where gcc
compiler is deleted, clang (3.3) is the default now.

Using unmodified source files from gtest-1.7.0/fused-src folder.

Added hiding global symbols for macho32 and macho64 in x86inc.asm.
This was done to fix exported symbol issue in Chrome build.

Current x86inc.asm didn't handle 32bit PIC build properly.
TEXTRELs were seen in the library built. The PIC macros from
libvpx's x86_abi_support.asm was used to fix this problem.
The assembly code was modified to use the macros.

Notes: We need this fix in for decoder building. Functions in
encoder will be fixed later.

Fixes an issue where newer versions of GCC would try to compile the
visual studio inline assembly.

Fixes issue #571

'CPU amdnop' is supported by YASM only.

Some projects must define only win64 for Windows 64bit builds using
yasm.

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().

The example encoder down-samples the input video frames a number of
times with a down-sampling factor, and then encodes and outputs
bitstreams with different resolutions.

Support arbitrary down-sampling factor, and down-sampling factor
can be different for each encoding level.

For example, the encoder can be tested as follows.
1. Configure with multi-resolution encoding enabled:
../libvpx/configure --target=x86-linux-gcc --disable-codecs
--enable-vp8 --enable-runtime_cpu_detect --enable-debug
--disable-install-docs --enable-error-concealment
--enable-multi-res-encoding
2. Run make
3. Encode:
If input video is 1280x720, run:
./vp8_multi_resolution_encoder 1280 720 input.yuv 1.ivf 2.ivf 3.ivf 1
(output: 1.ivf(1280x720); 2.ivf(640x360); 3.ivf(320x180).
The last parameter is set to 1/0 to show/not show PSNR.)
4. Decode:
./simple_decoder 1.ivf 1.yuv
./simple_decoder 2.ivf 2.yuv
./simple_decoder 3.ivf 3.yuv
5. View video:
mplayer 1.yuv -demuxer rawvideo -rawvideo w=1280:h=720 -loop 0 -fps 30
mplayer 2.yuv -demuxer rawvideo -rawvideo w=640:h=360 -loop 0 -fps 30
mplayer 3.yuv -demuxer rawvideo -rawvideo w=320:h=180 -loop 0 -fps 30

The encoding parameters can be modified in vp8_multi_resolution_encoder.c,
for example, target bitrate, frame rate...

Modified API. John helped a lot with that. Thanks!
