New and improved dev_debug_vboot

This new version adds a bunch more output, displays the TPM rollback version
values (if it can; Cr-48 doesn't export this info through crossystem), looks
for and validates all kernels on all devices, etc.

It also add some command-line arguments to use to examine files containing
BIOS, kernel, and disk images.

BUG=chromium-os:6676
TEST=manual

Boot, wait a minute or so, then log in and go to chrome://system
Click the Expand button for "verified boot". You should see a bunch of
useful text describing the firmware and kernel partitions.

I tried this on Cr-48, Stumpy, and Kaen.
