Subject: [PATCH 67/69] libparted: Add hfs_esp partition flag to GPT.
Mac uses a HFS+ formatted partition for ESP. When dual booting with
Linux we need a way to differentiate between the Mac partition and the
one created by Linux which contains just enough stuff to fake OSX into
displaying a nice logo and allowing it to be selected for boot. I
generated a GUID (47CB5633-7E3E-408B-B7B8-2D915B7B21B1) and added a new
flag to control it.

** Changes in behavior
+ Added new GPT partition type flag, hfs_esp, that sets the GUID to
+ 47CB5633-7E3E-408B-B7B8-2D915B7B21B1 so that you can distinguish
+ between OSX's native HFS+ partition and one used Linux on UEFI. The
+ way Mac handles UEFI is unique, it only uses the standard ESP for
+ firmware updates and needs a HFS+ formatted partition for UEFI. This
+ GUID will allow dual booting Linux systems to determine the correct
+ partition to use when upgrading or re-installing systems.
+
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.
