Subject: [PATCH 66/69] libparted: Add UEFI System Partition flag.
This adds support for the ESP partition type on MS-DOS. It also aliases
it to the boot flag on GPT which sets the ESP GUID type.
* NEWS (Changes in behavior): Mention it.
* doc/C/parted.8: Document esp flag.
* doc/parted.texti: Document esp flag.
* include/parted/disk.in.h (_PedPartitionFlag): Add PED_PARTITION_ESP flag

** Changes in behavior
+ Added new partition type flag, esp, to set the type to 0xEF on MS-DOS.
+ Also aliased to boot on GPT to set the UEFI ESP GUID.
+
Added new partition type flag, irst, for use with Intel Rapid Start
Technology. On MS-DOS disk labels it sets the type to 0x84 and on GPT
it sets the GUID to D3BFE2DE-3DAF-11DF-BA-40-E3A556D89593.
