When writing a GPT partition table, merge all actions into a single commit.
This avoids unnecessary udev events, which in some cases were causing udevd to trigger a kernel partition table reread, causing the kernel to get out of sync with drakx. In order to do so, the libparted bindings are enhanced so that we manipulate a 'ped_disk' object: - disk_open() returns such an object - set_disk_type() is removed - disk_commit() writes back the partition table and tell the kernel about it if we fails to write the partition table, we let partition_table::write() fire an exceptionc if we only have succeed in writing the partition table, we let partition_table::write() try harder (umounting partitions before trying againt to tell the kernel again) - need_to_tell_kernel() is overrided The last change is needed because we now tell the kernel about the new partition layout in partition_table::gpt::write() when calling disk_commit() while previously we were deferring that to partition_table::write() which after having called the gpt's write() calls tell_kernel() -> c::tell_kernel_to_reread_partition_table() So we must tell partition_table::write() that telling the kernel to reread the partition_table is not needed if we already succeeded in that.
