[patch] fdisk: show value range for partition offset/size

[Gregor Best]

Hi people,

the following patch changes the prompt for the 'Partition size' and
'Partition offset' prompts in fdisk to show the range of allowed values
and display the raw value as well when showing an error for out of
bounds values.
