Make cgpt_add error messages a little more verbose

Browse Source 
When the cgpt utility complaints about parameter errors, it is
impossible to tell what exactly went wrong. This change consolidates
error definitions and adds a function to convert integer error values
into text messages.

BRANCH=none
BUG=none
TEST=manual
  . emerge-link vbooot_reference
  . copy generated `cgpt' to a Link device
  . run command with wrong arguments with respect to the existing GPT:
   localhost var # ./cgpt add -i 3 -b 3985408 -s 1757184 -t rootfs -l ROOT-A /dev/sda
   ERROR: cgpt add: Starting LBA overlaps
   ERROR: cgpt add: -i 3 -l ROOT-A -b 3985408 -s 1757184 -t 3CB8E202-3B7E-47DD-8A3C-7FF2A13CFCEC
  . on the host, in the chroot in src/platform/vboot_reference run

   $ make && make runtests

   observe all tests succeed
