cgpt: Properly show ChromeOS-scheme MTD partitions
When working on NAND, we do not actually work with one device name. We
work on a temporary file instead. Moreover, depending on the type of the
partition, we need to show different devices.

Add cgpt_wrapper binary to transparently support NAND
This CL adds a "cgpt_wrapper" binary that will forward to "cgpt" binary
as needed to transparently support NAND.
The idea is that if we are working with an MTD device, this binary will
exec out to "flashrom" to read in the GPT section, then exec out to the
actual "cgpt" binary to work on that file, and finally write it back
with "flashrom".
This CL introduces a make target "install_mtd" to install this wrapper.
The corresponding ebuild should use this make target when "mtd" USE flag
is on.

vboot: cgpt: Treat drive_path as the GPT storage
Previously, "cgpt" called out to "flashrom" directly to read and write
NOR area. This CL removes that dependency and always treats "drive_path"
as the storage of GPT structs. This makes it consistent that whatever
device that cgpt reads from or writes to is always the device that
stores GPT structs. We only need to pass in the size of the drive that
contains the partitions, but we do not need to access to that drive.
More information is in the bug.

Port MTD structures to use 64-bit byte offsets instead of sectors.
As per the discussion on issue 221745 we will be using 64-bit byte offsets
for the MTD partition table and converting to/from sectors internally in cgpt.
Existing interfaces do not change, eg sizes are still reported in sectors, only
the on-disk representation is affected.

Refactor CgptAdd and CgptPrioitize to remove gpt-specific code
- Refactor cgpt_prioitize.c to completely remove gpt-specific code.
- Refactor cgpt_add.c to isolate gpt-dependence to one helper function
and the backup/restore logic
- Change several common apis to take a struct drive* rather than a GptData*,
this provides a path to cleanly implement mtd versions

Apply consistent naming scheme for hostlib functions.
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.

Implementation of CgptManager C++ library and unit tests.
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.

Refactor of cgpt tool for 32->64 autoupdate work.
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.
BUG=chromium-os:25374
TEST=Tested with existing cgpt unit tests as well as running the cgpt commands manually.
