93cf15e9a1 Introduce GUID type for Chrome OS read/write firmware. 
This change teaches cgpt a new GUID type to be used for the Chrome OS
read/write firmware. The GUID is CAB6E88E-ABF3-4102-A07A-D4BB9BE3C1D3.

BUG=chrome-os-partner:4843
TEST=Built and installed on my host, used a separate change to repurpose
partition 11 for the R/W firmware using cgpt and the "firmware" type, inspected
the image using cgpt. Built and installed an image and used cgpt on the device
to inspect it's GPT.

3430b32667 Add 'prioritize' command to cgpt tool. 
This lets us reorder the priority of all the kernel partitions with a single
command, instead of a bunch of complicated and error-prone shell script
logic.

In the chroot, do this:

cd ~/trunk/src/platform/vboot_reference
make
make runtests
make clean

Everything should pass.

500b3c2369 Fix for un-initialized code point variable. 
The original CL is http://codereview.chromium.org/5025003/, but it was reverted
because the compiler complains code_point variable is not initialized. This CL
just initializes it.

This CL also adds few lines of code to make code more robust.

6965cbfed3 The right implementation of CGPT label conversion between UTF8 and UTF16. 
For security quick fix, the original UTF8/UTF16 conversion only supports
ASCII area. This CL extends the library to support multiple code units
conversion between UTF8 and UTF16. The UTF8/UTF16 encoded byte(s) would be
decoded to code point first, then be encoded to UTF16/UTF8 correspondingly.

Bill, please kindly review the UTF8/UTF16 conversion.
Peter, please kindly comment if any security concern.

Thanks.

c4e92af85a Address some security concerns in the cgpt tool. 
1. Check for potential integer overflow in sector_bytes * sector_count.
2. Added O_NOFOLLOW to open() call - Is this enough?
3. Passing buffer length to GuidToStr(), PMBRToStr().
4. Use unsigned int in GetEntry() to determine stride.
5. Address conversion between UTF16 and UTF8.

Note: The UTF conversion is complex and troublesome, and needs careful
consideration to get right. For now, I've just forced the interpretation of
the partition name to 7-bit ASCII. That's sufficient for the needs of Chrome
OS, and I can file a new issue to handle UTF correctly.

BUG=chrome-os-partner:705
TEST=manual

Running "make runtests" invokes the tests/run_cgpt_tests.sh script, which checks the behavior and output of the cgpt tool.

f1372d9109 Nearly complete rewrite of cgpt tool. 
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.
