libparted: Add support for MBR id, GPT GUID and detection of UDF filesystem
This is needed for libparted based applications (like Gparted) to correctly
choose MBR id and GPT GUID for UDF filesystem. MBR id for UDF is 0x07 and
GPT GUID is Microsoft Basic Data, see why: https://serverfault.com/a/829172
Without registering a new libparted fs code it is not possible to assign
MBR id or GPT GUID.
Detection of UDF filesystem is done by checking presence of UDF VSD (NSR02
or NSR03 identifier) and UDF AVDP at expected locations (blocks 256, -257,
-1, 512).
