(cherry picked from commit a91e5b4f)

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.

Previously, the microsoft arm assembler errored out, saying that
bilinear_taps_coeff was an undefined symbol.

The microsoft assembler can't handle the second register being
implicit.

The branch instructions are encoded as 16 bit instructions
by the microsoft assembler, while they are encoded as 32 bit
instructions by gnu binutils.

* changes:
  msvs: Don't link to winmm.lib
  msvs: Pass dependency project vcxproj files to the project generation script
  msvs: Support producing both vcproj and vcxproj depending on configure variables
  configure: Add x86*-vs10/11 targets
  gen_msvs_sln: Support producing versions 10 and 11, handle vcxproj files
  Add a new script for producing vcxproj files

Use a separate counter for resetting the pattern upon
a change in temporal layers, and set/initialize the
layer context parameters for the new temporal layer state.

Also moved the setting of layer configuation in init_config()
to a separate function.

This is required since the microsoft assembler claims that
add.w r12, pc, #10
generated unpredictable behaviour.

The formats are basically the same, but a few minor details need
to be adjusted. Addiitonally, when building for the WinRT/Windows
Phone 8 platforms, one has to build for thumb, so convert instructions
accordingly.

Linking to this library doesn't seem to be necessary, and this library
isn't available in the windows phone API subset.

Change-Id: I179837d6f9c7407f1cb6101533dc978316a30adf

This is required since the dependencies are specified within the
vcxproj files themselves, not in the solution file. This doesn't
do anything for the old vcproj files.

Using == ended up matching no matter what string was passed in
(which so far only happened if when the -thumb parameter
was set).

Currently this only supports thumb2.

This involves rewriting certain instructions that can't be expressed
in thumb2 into equivalent instruction sequences. The regexps for
rewriting are currently written pretty narrowly, only covering the
exact cases currently encountered in the code base.

No IT instructions are added (since that would require more logic than
plain regexps), so using the thumb mode requires enabling
-mimplicit-it=always/thumb.

When using 'always_inline' 'inline' should be specified as well.

The support for detecting hardfp toolchains in af9dd50e is a
step in the right direction, but that particular switch case
isn't executed at all if the toolchain variable is set.

This fixes cross building from x86 ubuntu to armhf ubuntu,
in configurations such as
"CROSS=arm-linux-gnueabihf- ./configure --target=armv7-linux-gcc".

vp9_dequantize_x86 has only sse2 functions.

vp9_dct_sse2_intrinsics has no namespace collision and can drop
_intrinsics.

vp9_idct_mmx.h is unused.

Remove similarly named header file. It is obsolete.

Move file to match naming style.

Adjust make file to include the file correctly and remove extra
unnecessary #if guard.
