[PATCH] To add FreeBSD GPT partitions

[Arun Sharma]

All,

The attached patch adds GPT GUIDs defined by FreeBSD to GNU parted. This allows 
the use of GNU parted to create Linux as well as FreeBSD partitions on a dual 
boot EFI GPT based platform.

The filesystem probe routines are dummy and should not be used. The main intent 
is to be able to create the GUID partitions but not necessarily create the 
filesystem or probe it correctly.

Please let me know if you have any comments.
