Subject: [PATCH parted 1/2] dos: Add a partition flag for diagnostics / recovery partitions
msdos partition tables can contain diagnostics partitions (often used
now a days as system recovery partitions). For some users of libparted
(ie anaconda) it is usefull to know if a dos partition is a regular partition
or a diagnostic partition (see rh bug 534066).
* include/parted/disk.h(_PedPartitionFlag): Add PED_PARTITION_DIAG
* libparted/disk.c(ped_partition_flag_get_name): Add PED_PARTITION_DIAG
* libparted/labels/dos.c: Add support for PED_PARTITION_DIAG flag

Subject: [PATCH parted 2/2] dos: Fix prep / palo flag handling
Setting the prep flag was not clearing the palo flag and vica versa
* libparted/labels/dos.c(msdos_partition_set_flag): Fix prep / palo
flag handling.
