Parted 1.4.20-pre2

[Andrew Clausen]

Hi all,

Changes:
* applied gpt patch from Matt Domsch (sorry I took so long!).  If a GPT
disk doesn't have a valid protective MBR, then it gives the option of either
removing the GPT stuff or creating a valid protective MBR.
* misc cleanups in gpt (libparted/disk_gpt.c)
* libparted/disk.c (ped_partition_new): the check for attempts to create
extended partitions on non-extended partition tables was extended to logical
partitions as well
