18e03706df Clean up exported Mtd* functions
A lot of functions were added some time ago, nominally to support keeping
the firmware in an MTD device that wasn't formatted with the GPT headers.
That work was never completed, so these functions aren't used anywhere.

We may want to resurrect this work at some future point. Until then, this CL
just moves some of the functions into an "unused" file.

BUG=chromium:231567
BRANCH=ToT
TEST=manual

All tests pass, all firmware and external repos build.

4cb5497984 Remove cgpt app-specific symbols from libvboot_host.a
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.

494646dbad Fix some issues with LBA vs byte offsets
In several places the existing code assumes LBA, but was improperly converted
to use byte offsets, so multiply by the sector size to correct it and maintain
the same interface between MTD & GPT.

Also, since we will need to cgpt create on /dev/fts, which isn't a stat()able
device, allow providing the disk size on the commandline.

289b604f61 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.

3f806a2abf 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.

66b47ba37d cgpt: verify the modifications of 'cgpt add' before effected.
Current code only does basic check on parameters, but doesn't validate
if it can pass the CheckEntries(). So a user can accidentally break
the cgpt table by:

  cgpt add /dev/sda -i 6 -s 0  # 0 sector is not allowed for a partition.

  cgpt show /dev/sda
  ... INVALID_ENTRIES ...

This CL checks the new entry before we write it to disk. If new entry is
not good, we return fail.

5fac757abe Enable building of Cgpt C++ Library for 32-bit.
The existing library had a bunch of dependencies which are too many to
build for the 32-bit platform. So this checkin prunes the dependency
list by building only things that are absolutely required for the

Made the use of libuuid restricted only to cgpt and unit tests so that
libcgpt-cc.a doesn't depend on it.

250549d3e7 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.

     ran existing cgpt unit tests,  as well as running the

     also build fine with these changes.
