Add the config directory to the rtcd generation script. libvpx is
configured in the jni directory but ndk-build is intended to be run from
the next directory up. Currently it needs to be run from the jni
directory but this is being looked in to.

Add a trailing slash to allow the variable to be empty.

Reduce offset generation to the files which are actually used.

Linking when we don't use it but it is available is probably harmless.

Gtest requires pthreads. Don't automatically enable unit tests if we
don't have it.

This file is currently unused, as the asm that depended on it has been
disabled for the current roll into Chromium. It's expected that it
will return in some form, so wrap it in an x86 check rather than
deleting it. This extra file isn't really an issue with the libvpx
build system, but affects the gyp builds since on ARM (android) it
tries to do the ADS->GAS conversion on all .asm files reported in
libvpx_srcs.txt.

Rather than building an object file directory heirarchy matching the
source tree's layout, rename the object files so that the object
file name contains the path in the source file tree. The intent here
is to allow two files in different parts of the source tree to have
the same name and still not collide when put into an ar archive.

We need an easy way to build the unit test driver without running the
tests. This enables passing options like --gtest_filter to the
executable, which can't be done very cleanly when running under
`make test`.

Fixed a number of compiler errors/warnings when building the tests
in various configurations by Jenkins.

The commit introduces a make target 'testdata' that downloads the
required test data from the WebM project website. The data will also
be downloaded if invoking `make test` but is not a strict requirement
for only building the test executable.

The download directory is taken from the LIBVPX_TEST_DATA_PATH
environment variable, or may be specified as part of the make command.
If unset, it defaults to the current directory. It's expected that
most developers will want to set this environment variable to a place
outside their source/build trees, to avoid having to download the data
more than once.

To add test data file:

  1) add a line to test/test.mk:

      LIBVPX_TEST_DATA-yes += foo-bar-file.y4m

  2) add its sha1sum to the test/test-data.sha1 file in the following
     format:

      528cc88c821e5f5b133c2b40f9c8e3f22eaacc4c  foo-bar-file.y4m

  3) upload the file to the website

      $ gsutil cp foo-bar-file.y4m gs://downloads.webmproject.org/test_data/libvpx

This implementation will check the integrity of the test data
automatically if the `sha1sum` executable is available.

vpx uses symbols in libm and thus we need to provide an indication to

also link against libm.

Update the Visual Studio builds to support the new monolithic unit
test binary.

Includes minor semi-cosmetic refactoring of solution.mk, as the
%vpx.vcproj match is no longer appropriate given the test_libvpx
target.

Rework unit tests  to have a single executable rather than many, which
should avoid pollution of the visual studio project namespace, improve
build times, and make it easier to use the gtest test sharding system
when we get these going on the continuous build cluster.
