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
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.

multi-res: restore v1.0.0 API
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.

I've forward-ported it to the current version (which mostly

native Fennec, since it does not support them at all.

Fix loopfilter race condition in multithreaded encoder
Race was introduced by https://gerrit.chromium.org/gerrit/15563.
If loopfilter related config params were changed between frames, or
after a KEY frame, there could be a mismatch between encoder's and
decoder's recontructed image. In worst case, when frame buffers are
reallocated because of a size change, the loopfilter could
do an invalid data access (segmentation fault).
Fixes:
Sync with the loopfilter before applying any encoder changes in
vp8_change_config().
Moved the loopfilter synching to the top of
encode_frame_to_data_rate() so that it's done before any alteration of
the encoder.
