This CL also includes 4 pieces:
1. main files: environment-independent (main.c) and
-dependent (ec_keyboard_test.c).
2. stub files: chip_stub/keyboard.c simulates the real hardware.
chip_stub/keyboard.h is the header of testing functions.
3. initial keyboard lib code: ec_keyboard.h
4. rename Cr* function name to Ec* under chip_interface/.
BUG=None
TEST=make && make runtests
Expect seeing the output debug message from cros_ec/lib/ec_keyboard.c.
