During some of the previous Depthcharge and firmware image updates I
forgot to update the date in the binary file names. Modify them to match
the Depthcharge build date shown in the boot log.

Also, track the rammus firmware binary in cros-build instead of in
cros-build/firmware.

This adds a custom build script for 'kevin' ('gru') that doesn't rely on
Docker, as the cros_sdk for gru doesn't support the --nouse-image flag.

The script (cros_build/build_kevin.sh) takes care of downloading the
sources and creating a sdk chroot appropriately. Once inside the chroot,
to build the firmware run:

  ./kevin.sh setup
  ./kevin.sh checkout
  ./kevin.sh build

and the resulting firmware binary will be in
cros_build/build_kevin/kevin.bin.

All the downloaded and generated files will be contained in the
cros_build/build_kevin directory.

This also includes the custom firmware binary for
kevin (firmware/kevin.bin), although it wasn't tested.

This replaces the coral FW image with one that adds a commit by Julius
Werner (45f2be285df6c78b657304198d736e33a9992cc2) to increase the
allowed payload size of Depthcharge. This change was already present in
the firmwares of grunt, rammus and octopus, but missing in
coral. Depthcharge can now download up to 512MB of kernel + ramdisk
data.

Normally, a ChromiumOS SDK comes with a set of Servo binaries installed
in /usr/share/servo_updater/firmware, but this is not advertised in the
SDK and there's no way to know which Servo v4 FW version comes with a
specific SDK version.

We found a web archive of Servo v4 firmwares in
https://gsdview.appspot.com/chromeos-localmirror/distfiles/



this is where these firmware binaries come from. These are the ones we
have tested so far.

Add commands to either enter the CrOS SDK chroot or open a shell in
the container, interactively or with some arbitrary commands.

For example, this makes it possible to call the bootstrap.sh script
and invoke a build script in the chroot to set everything up and build
a firmware image all in one go.

Add octopus.sh script to set up the CrOS SDK chroot for octopus, build

Add servoflash.py as a better tool than device-specific scripts such
as flash-kevin.sh.  This will use the google-servo.conf file to look
up a device's serial number, so the user only has to provide the
device name.

It will not downnload any firmware file automatically, that still has
to be done by the user.
