Also add a script for splitting a firmware image into component firmware data, vblocks and the GBB.
Note: The script uses fmap_decode, a utility to parse flashmap of a firmware image, and a part of the flashmap project:
http://code.google.com/p/flashmap/
BUG=3496
TEST=Tested with newer builds of firmware images with flashmaps enabled. Steps to verify:
1) Use script to re-sign an existing image with a new set of keys.
2) Use unpack_firmwarefd.sh to get individual firmware data and vblocks.
3) Use vbutil_firmware with the new keys. Verification should succeed with
the newer keys but fail with the older ones.

For use on our signing servers. May merge this with other scripts once we drill down the right workflow.
BUG=3496
TEST=Just a wrapper around vbutil_kernel and works as intended.

Also created a new directory in the vboot_reference source where all signing scripts and related miscellanea will go.

Refactor and restructure reference code into individual self-contain modules. I have revamped the way the code is structured to make it easy to determine which parts belong in the firmware and which are used by userland tools.
