When building with new versions of Clang we encounter some issues. Work
around them by adding -fno-strict-aliasing when we detect Clang.

currently threading is internal to libvpx so thread safety is unneeded
in libgtest -- visual studio builds already operate in this way as they
do not have pthread.h available by default.

this removes an unconditional link to libpthread using $(extralibs)
should libvpx require it.

This version of the loop filter supports non-4:2:0 subsampling and
a fourth plane, as well as changing the filtering order to be more
friendly to hardware implementations.

The filters are applied first to all vertical edges within the
64x64 SB, followed by the top horizontal edge and any internal
horizontal edges. Since filtering is applied on each 4x4 edge
serially, a dependency is created from filtering one block edge
to the next. It would be possible to remove this depencnecy by
building all filtering decisions from the unfiltered
reconstruction data.

This patch removes the implicit segmentation
experiment from the code base as the benefits
were still unproven as of the bitstream deadline.

This patch changes the coefficient tree to move the EOB to below
the ZERO node in order to save number of bool decodes.

The advantages of moving EOB one step down as opposed to two steps down
in the other parallel patch are: 1. The coef modeling based on
the One-node becomes independent of the tree structure above it, and
2. Fewer conext/counter increases are needed.

The drawback is that the potential savings in bool decodes will be
less, but assuming that 0s are much more predominant than 1's the
potential savings is still likely to be substantial.

This commit fixed the unit test failure issues. It also resolved
the merge conflicts between 4x4 block level partition and iterative
motion search for comp_inter_inter.

The arm assembly files are named .s after conversion, to reuse
as much of the existing makefile infrastructure for conversion to
gas format as possible. Within the generated visual studio project,
only the converted assembly sources are available, which might not
be optimal for actually developing it, but is acceptable for
just building the library.

Multithreading is disabled since the traditional win32 threading
functions aren't available on WinRT/Windows Phone 8.

Building of vpx itself and the examples succeed, while building the
tests fail due to them using functions not available in the
windows store/windows phone API subsets - therefore the unit tests
are disabled.

This works for building in Visual Studio Express 2012 for Windows
Phone, while Visual Studio Express 2012 for Windows 8 (for
"Windows Store" apps) seems to reject the vcxproj files due to
not supporting "classic style native application or managed
projects". The built static library should be compatible with that
platform though.

This is a mostly-working implementation of an extra channel in the
bitstream. Configure with --enable-alpha to test. Notable TODOs:

 - Add extra channel to all mismatch tests, PSNR, SSIM, etc
 - Configurable subsampling
 - Variable number of planes (currently always uses all 4)
 - Loop filtering
 - Per-plane lossless quantizer
 - ARNR support

This implementation just uses the same contents as the Y channel
for the A channel, due to lack of content and general pain in
playing back 4 channel content. A later patch will use the actual
alpha channel passed in from outside the codec.

In current code, motion vectors got from single prediction mode are used
in compound prediction mode directly. These motion vectors may not give
accurate prediction since they are searched independently. In this patch,
we took Pascal's suggestion, and did joint motion search in compound
prediction mode to find better motion vectors in this situation.
Test results:
Overall PSNR: 0.570%(derf), 0.918%(stdhd);
SSIM: 0.572%(derf), 1.009%(stdhd);

The encoder is a little slower. This can be improved since some c
code is used in motion search.

Adds a new experiment CONFIG_NON420 that allows other chroma subsamplings
to be passed to the codec. This commit allows the data to be passed from
a y4m input file through vpxenc to the codec, where they're currently
rejected. Later commits will finish support for this inside the codec.
