This extends the denoiser to work for temporally scalable
coding.
I believe this also fixes a very rare but really bad bug in the original
implementation.

vp8_scalable_patterns in line with the other examples.

In multi-resolution encoding, frame_type decision for each frame
is made by the lowest-resolution encoder. For all other higher-
resolution encoders, kf_mode is always set to VPX_KF_DISABLED,
and they are forced to use the same frame_type picked by the
lowest-resolution encoder.

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.

Accept the same range of inputs for the VP8E_SET_NOISE_SENSITIVITY
control, regardless of whether temporal denoising is enabled or not.
This is important for maintaining compatibility with existing
applications.

Adds a unit test to the boolcoder that tests encoding
and decoding thousands of different bits, with different
probabilities in different patterns.
Code borrowed from the webp project - and its committers.

Make functions only referenced from one translation unit static. Other
symbols with extern linkage get a vp8/vpx prefix.

Change If4321cc5 fixed a bug caused by forward declarations not being
kept in sync across C files, resulting in a function call with the
wrong arguments. The commit moves the affected function declarations
into a header file, along with the other symbols from encodeframe.c
that were being sloppily shared.

Removes all runtime initialization of global data. This commit is a
squashed version of the following series cherry-picked from master.
This is necessary because of a change that was merged to the tester
that depends on the scaler being moved to the RTCD framework, which
is a worthwhile thing to include in Eider anyway.
- a91b42f02 Makes all global data in entropy.c const
- b35a0db0e Makes all global data in tokenize.c const
- 441cac8ea Makes all mode token tables const
- 5948a0210 Ports vpx_xcaler to new RTCD method
- 317d4244c Makes all mode token tables const part 2

Move the notion of 0 bitrate implying skip deeper into the codec,
rather than doing it at the multi-encoder API level. This preserves
v1.0.0 ABI compatibility, rather than forcing a bump to v2.0.0 over a
minor change. Also, this allows the case where the application can
selectively enable and disable the larger resolution(s) without having
to reinitialize the codec instace (for instance, if no target is
receiving the full resolution stream).
It's not clear how deep to push this check. It may be valuable to
allow the framerate adaptation code to run, for example. Currently put
the check as early as possible for simplicity, should reevaluate this
as this feature gains real use.

Original patch by Ginn Chen <ginn.chen@oracle.com> against libvpx
v0.9.0.
I've forward-ported it to the current version (which mostly
involved removing hunks that were no longer relevant), since I've
given up on getting Ginn to submit this upstream himself.

Besides imposing a performance penalty at startup in most
configurations, these relocations break the dynamic linker for
native Fennec, since it does not support them at all.

These values can be overridden with some poorly documented and
overloaded options: --libc and --sdk-path
../libvpx/configure --target=armv7-darwin-gcc --sdk-path=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer --libc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/
So for someone who still wants to build with the iOS 5 SDK, the last
part of the path should be iPhoneOS5.0.sdk

The ARNR filter uses MC to find the best match between the
ARF and other nearby frames in the filter-set. Since the
ARF is a member of the filter-set, MC in that case is
unnecesssary. This patch modifies the filter so it does
not apply MC in this case.

The ARNR filter uses a motion compensated temporal filter,
but the motion estimation implementation accounts for the
cost of the mv in its decision making process. The ARNR
filter uses a dummy cost table initialized to 0 as a way
to ignore the mv costs (which are irrelevant to the filter).
This CL modifies the ARNR filter implementation so that
the mv costing is ignored without the requirement for
dummy tables.
