Three symbols used by the standalone cgpt executable were being referenced
in the files used to create the external libvboot_host.a needed by non-vboot
userspace applications.
This cleans things up so those symbols don't have to be explictly defined
by other repos just to link with that library.

The chromeos-installer uses several functions from the vboot_reference
userspace library, but the names of those functions are inconsistent:
IsZero
MapFile
VbGetSystemPropertyString
cgpt_add
cgpt_boot
cgpt_create
cgpt_get_boot_partition_number
cgpt_get_num_non_empty_partitions
cgpt_get_partition_details
cgpt_prioritize
cgpt_set_attributes
find_kernel_config
The Google C++ style guide says types and functions should use CamelCase,
while variables use lower_case_with_underscores.
Kernel style (which vboot_reference tries to be more-or-less compatible
with) uses lower_case_with_underscores for everything, but that really only
has to apply to firmware stuff. For userspace, we can use the Google style.

CgptManager exposes the cgpt commands via a C++ library so that
the post-installer for 32- to 64-bit upgrade can link directly
against a library and thus avoid any shell dependency.
The default make target will not build libcgpt-cc.a since it
requires some dependencies that are available only in chroot.
A separate follow-up checkin to the vboot_reference
ebuild will enable emerging the libcgpt-cc.a by default.
BUG=chromium-os:25374
TEST=Tested with the new unit tests for CgptManager,
ran existing cgpt unit tests, as well as running the
cgpt commands manually. Built on both amd64 and x86.
Tested that vboot_reference is also buildable outside of chroot.
Tested that vboot_reference-firmware and vboot_reference-tests
also build fine with these changes.

This check-in splits the cgpt into two layers. The top layer (cmd_* files) does
the command-line parsing and the bottom layer (cgpt_* files) does the actual
cgpt work.
This is done so that the bottom layer can be reused for the monolithic
C++ post-installer code that will be done in subsequent checkins.

TEST=Tested with existing cgpt unit tests as well as running the cgpt commands manually.

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.

This issue disclosed a bug of cgpt. The bug comes from the 'show' command always
reads the primary entry table when '-i partition' is specified. I added an
ANY_VALID constant for GetEntry to automatically select valid entry table.
Also fixed the bugs in cmd_boot.c and cmd_find.c. In cmd_add.c, stop user to
continue if any header/entry table is invalid.
Also fixed the bug that untrusted header size could cause segmentation failure.
Hungte, this is FYI. But welcome to do review.

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.

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

This is part of the proposed developer-mode installation process, where we
want to detect that whoever is fiddling with the hard drive has already
fiddled with it before. Otherwise, we'll make them wait a bit to prevent
drive-by updates.
