This fixes a number of bugs, adds a bunch of commands, and essentially makes
cgpt ready to use as a replacement for gpt. Still to do is to add commands
and options that will let it generated intentionally bad partitions, for use
in testing.

Also includes part of LoadKernel(), which I'll split into a separate
CL. With some hacks, gets into VerifyKernel() before dying because
I'm not passing in the right key blob.
cgptlib is now pretty stable, and worth looking at. LoadKernel() less so.
Thanks,
Randall
