libfdisk: count gaps to possible size when resize
The current code counts only partition sizes when it counts possible
space, but we have gaps between the partitions. It seems better to
count all based on offsets rather than sizes.

libfdisk: accept grain script header
The "grain" variable is used to calculate partitions alignment. The
default is 1MiB (or minimal I/O size). The libfdisk provides API to overwrite
this default, but this feature has been nowhere accessible for
end-user.
This patch support for "grain: <size>" in libfdisk scripts.
