Add standalone lightbar simulation tool
This adds an "extra/" directory to hold various experiments and optional
programs. With this change, we add a tool that can simulate the lightbar
behavior on the build machine. That can be used to experment with variations
in the lightbar pattern code without needing to reflash a Pixel with a new
EC to see the effect.
There is no functional change to the EC code, just a couple of #ifdefs to
allow common/lightbar.c to be compiled separately from the EC.
BUG=none
BRANCH=ToT
TEST=make buildall -j
cd extra
make
./lightbar
You may need to install the libxcb1-dev package on your build machine.
