First attempt at avoiding all the compile-time environment detection for

this commit changed the asm file compiling in MSVC to use individually
customized build command line with object filename specified for each
input file. This allows object filenames prefixed with path name, and
avoid name collision in link time
Change-Id: I996098643dcadc393af57035a04bef3877f45424
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.

The current parsing logic of the dumpmachine tuple lacks any arm

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.

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.

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 \

--disable-runtime-cpu-detect \
--enable-realtime-only \
--disable-neon \
--cpu=cortex-a9 \

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.

Add initial keyframe tests
Move all tests to test/ directory
Enable unit tests by default
Build unit tests monolithically
configure: initial support for CXX, CXXFLAGS variables
Use CXX rather than assuming g++ to invoke the compiler. Also introduce
separate CXXFLAGS, as certain CFLAGS we enable by default cause warnings

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

These values can be overridden with some poorly documented and

This is a proof of concept RTCD implementation to replace the current
system of nested includes, prototypes, INVOKE macros, etc. Currently
only the decoder specific functions are implemented in the new system.
Additional functions will be added in subsequent commits.
Overview:
RTCD "functions" are implemented as either a global function pointer
or a macro (when only one eligible specialization available).
Functions which have RTCD specializations are listed using a simple
DSL identifying the function's base name, its prototype, and the
architecture extensions that specializations are available for.
Advantages over the old system:
- No INVOKE macros. A call to an RTCD function looks like an ordinary
function call.
- No need to pass vtables around.
- If there is only one eligible function to call, the function is
called directly, rather than indirecting through a function pointer.
- Supports the notion of "required" extensions, so in combination with
the above, on x86_64 if the best function available is sse2 or lower
it will be called directly, since all x86_64 platforms implement
sse2.
- Elides all references to functions which will never be called, which
could reduce binary size. For example if sse2 is required and there
are both mmx and sse2 implementations of a certain function, the
code will have no link time references to the mmx code.
- Significantly easier to add a new function, just one file to edit.
Disadvantages:
- Requires global writable data (though this is not a new requirement)
- 1 new generated source file.

This adds the magic .note.GNU-stack section at the end of each ARM
asm file (when built with gas), indicating that a non-executable
stack is allowed.
Without this section, the linker will assume the object requires an
executable stack by default, forcing an executable stack for the
entire program.
