gen_asm_deps.sh: regex fix
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.

Add support for downloading test data
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:

Disable unit-tests. The logging in GTest would need to be adjusted.

Change #if defined(HAVE_*) to #if HAVE_* because we only need to check

been harmless, as disabled feature sets wouldn't have any features to

Soft enable runtime cpu detect for armv7-android target, so that it

Remove threading dependencies with --disable-multithread
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.

Frame dropping decision is made by evaluating both current frame

Reset Q for key frame when spatial resizing occurs.
The logic for spatial resizing is done after the Q is selected for the
frame. This causes a problem that the Q we select for the (resized)
key frame may be based on a different resolution than the frame we
will encode.
This fix is to ensure that, when resize is on, the selected Q is still
based on the resolution of the frame to be encoded.

Allow target autodetection to work when cross-compiling.
Allow CHOST to override the gcc -dumpmachine output. This allows to
use the target autodetection code when cross compiling by setting the

On Gentoo, we would like to support easy cross-compilation, and for
libvpx this would basically mean copying the code in
build/make/configure.sh to setup the right --target option. It seems a
lot easier to let it guess by itself.
Another option I considered was using CROSS-gcc instead but this would
not work for our multilib setups: They use gcc -m32 to build 32bits
binaries and gcc -m32 -dumpmachine will output the 64bits version,
which would then make libvpx wrongly believe it is building for a
64bits architecture.
