This CL accesses the partition entry array through its header's
entries_lba value.
Previously, we assume the primary entry array lies on third sector, and
the secondary array lies (1 + 32) sectors from disk end. This assumption
was fine, even Wikipedia assumed the same.
But in order for us to support writing boot code to the third sector (as
required by some Freescale board), the primary entry array must be moved
to another location. Therefore, we must use "entries_lba" to locate the
arrays from now on.

TEST=unittest
TEST=`cgpt create -p` and then `cgpt show`. Make sure the table
header and entries are properly moved.

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.

- 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
