Integrates the FTS driver into cgpt. This driver is binary-format compatible with the linux driver for interoperabiilty. The cgpt changes load & store a hex-encoded mtd partition table in the FTS; we need some sort of encoding because FTS only stores NUL-terminated strings. Currently, the mtd code paths aren't executed in cgpt, only in the tests. It's also not hooked up to the vboot code yet, we will need to do that eventually.
