This unit test tests vp8_sixtap_predict function against preset
data and random generated data. The test against preset data
checks the correctness of the functions, and the test against
random data checks if the optimized six-tap predictor functions
generate matching result as the c functions. It tests the
following functions:
vp8_sixtap_predict16x16_c
vp8_sixtap_predict16x16_mmx
vp8_sixtap_predict16x16_sse2
vp8_sixtap_predict16x16_ssse3
vp8_sixtap_predict8x8_c
vp8_sixtap_predict8x8_mmx
vp8_sixtap_predict8x8_sse2
vp8_sixtap_predict8x8_ssse3
vp8_sixtap_predict8x4_c
vp8_sixtap_predict8x4_mmx
vp8_sixtap_predict8x4_sse2
vp8_sixtap_predict8x4_ssse3
vp8_sixtap_predict4x4_c
vp8_sixtap_predict4x4_mmx
vp8_sixtap_predict4x4_ssse3

This patch fixed issue 458 by calling copy function when both
offsets are 0, which guarantees the SSSE3 functions output
same result as the c function for all possible offsets.

xd->subpixel_predict16x16 is called in first pass, but isn't
initialized in first pass, which causes segfault. This patch
fixed that problem.

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.

Fixed the quantifier that optionally matches a quote before the
filename. This was originally reported in the homebrew project[1].
Note that this fix is different than patch posted there, as there are
some platforms that don't have the quote, so it needs to be included
in the expression optionally.

Update the comment that defines the allowed ranges for
delta_q and delta_lf that can be used with segmentation.

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.

This is a unit test for the post-processing functions:
- vp8_post_proc_down_and_across_c
- vp8_post_proc_down_and_across_mmx
- vp8_post_proc_down_and_across_xmm

Disable unit-tests. The logging in GTest would need to be adjusted.
Restructure ARM cpu detection. Flatten if-else logic.
Change #if defined(HAVE_*) to #if HAVE_* because we only need to check
for features that the library was actually built with. This should have
been harmless, as disabled feature sets wouldn't have any features to
call.

Changes relating to Issue 411
Removed code that was clearing down the segmentation data each
frame.
Added range/parameter checking in vp8_set_roimap(); Return error
if called when cyclic_refresh is enabled.
Correct setup_features() so that it sets or clears the segment update
flags as appropriate.

Soft enable runtime cpu detect for armv7-android target, so that it
can be disabled and remove dependency on 'cpufeatures' lib.
Change the arm_cpu_caps implementation selection such that 'no rtcd' takes
precedence over system type.
Switch to use -mtune instead of -mcpu. NDK was complaining about
-mcpu=cortex-a8 conflicting with -march=armv7-a, not sure why.
Add a linker flag to fix some cortex-a8 bug, as suggested by NDK Dev
Guide.
Examples:
Configure for armv7+neon:
./configure --target=armv7-android-gcc \
--sdk-path=/path/to/android/ndk \
--disable-runtime-cpu-detect \
--enable-realtime-only \
--disable-unit-tests
...armv7 w/o neon:
./configure --target=armv7-android-gcc \
--sdk-path=/path/to/android/ndk \
--disable-runtime-cpu-detect \
--enable-realtime-only \
--disable-neon \
--cpu=cortex-a9 \
--disable-unit-tests

The function vp8_post_proc_down_and_across_c takes the
stride of both the src and dst images as parameters, but
assumes that they are the same.
I modified the code to use the correct strides, as the
assembler versions of these functions do.

vpx uses symbols in libm and thus we need to provide an indication to
the user of libvpx that if they want to link against libvpx they must
also link against libm.

Avoid a pthreads dependency via pthread_once() when compiled with
--disable-multithread.
In addition, this synchronization is disabled for Win32 as well, even
though we can be sure that the required primatives exist, so that the
requirements on the application when built with --disable-multithread
are consistent across platforms.
Users using libvpx built with --disable-multithread in a multithreaded
context should provide their own synchronization. Updated the
documentation to vpx_codec_enc_init_ver() and vpx_codec_dec_init_ver()
to note this requirement. Moved the RTCD initialization call to match
this description, as previously it didn't happen until the first
frame.

Allows building the library with the gcc -pedantic option, for improved
portabilty. In particular, this commit removes usage of C99/C++ style
single-line comments and dynamic struct initializers. This is a
continuation of the work done in commit 97b766a46, which removed most
of these warnings for decode only builds.
