by presenting the existing offset and size as the defaults. Enhance
getuint64() to take a minimum value as ask_num() does. Use this to
ensure that GPT partitions are constrained to the valid area of the
disk. Leave MBR partition constraints alone for the moment.

This commit contains the MBR part of the fix only. The GPT code needs a few

Reduce overburden of unnecessary #include's. Note that param.h is

so stdint.h is enough. General tidying up of #include sections.

1) If mbr_file is NULL use built-in mbr for -i, -u and 'reinit'.
2) If mbr_file cannot be opened issue a warning and use built-in mbr for -i,
-u, and 'reinit'.
3) If mbr_file can't be read, bail out of fdisk.
4) Use the mbr read from mbr_file for -i, -u, and 'reinit'.
Remove inappropriate GPT dancing.
This restores pre-GPT-editing mbr_file handling and makes the logic
clearer at the expense of a tiny bit of duplication.

in the GPT partition structure. And don't run off the end of the
name buffer by confusing sizeof() with the number of elements in

zap the old partition name before setting the new one, lest a short
new name leave bits of an old long name in place.
