Utility to dump boot timing table
Coreboot and u-boot create a table of timestamps which allows to see
the boot process performance. The util/cbmem/cbmem.py script allows to
access the table after ChromeOS boots up and display its contents on
the console. The problem is that shipping images do not include Python
interpreter, so there is no way to access the table on a production
machine.
This change introduces a utility which is a Linux app displaying the
timestamp table. Conceivably the output of this utility might be
included in one of the ChromeOS :/system sections, so it was attempted
to write this procedure 'fail safe', namely reporting errors and not
continuing processing if something goes wrong.
Including of coreboot/src .h files will allow to keep the firmware
timestamp implementation and this utility in sync in the future.
Test:
. build the utility (run 'make' while in chroot in util/cbmem)
. copy `cbmem' and 'cbmem.py' to the target
. run both utilities (limiting cbmem.py output to 25 lines or so)
. observe that the generated tables are identical (modulo rounding
up of int division, resulting in 1 ns discrepancies in some
cases)

Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.
