This updates the sources, README.chromium, and the libs.  The gyp file will be a
separate pass...

Are you two up for reviewing this, or should I bug someone else?

README.chromium:46: --disable-install-srcs --disable-examples --disable-postproc
--disable-psnr
should we keep --disable-psnr?

It's no longer supported by libvpx's configure script.

Patchset 2 adds the includes, which I missed in the initial patchset.

A question about the arm libs: do the libs in the commit need to be usable with
2009q3 arm compiler, or is it alright to require a newer release?  The arm libs
in this patchset were built using the 2010q1 release, and if used with with the
2009q3 release builds will fails and error text similar to "unknown EABI
attribute 44" will be emitted.

Outside of that question this is ready to land.

LGTM
the arm libs are nice to have, but we build from source.
