The current code uses 'M' to switch between MBR and GPT, but it's not
intuitive to "go back" by 'M'. It seems more user-friendly to use 'r'
as in another places (for example when go from expert menu or from BRD
menu).
The 'M' to return to GPT is still supported for backward compatibility.

It is not guaranteed that the returned string of readline() actually
contains as many bytes as buf can contain.
If bufsz is larger than the allocated memory by readline, an out of
boundary read occurs and leads to undefined behaviour. Most likely
that will be a crash.
This can be reproduced when readline-support is compiled in and when
you directly enter "quit" and "n" (to not write changes back to disk)
when sfdisk was called with any given device.

when `NCURSES_WIDECHAR` is defined. This define is actually getting set
in the same header file, but only in case `_XOPEN_SOURCE` is defined and
has a value of 500 or higher. As we already have the precedence of
defining `_XOPEN_SOURCE` to a value of 600 in some other files, simply
define it to the minimum required value of 500 in "cfdisk.c". This

$ mkfs.cramfs -p -N big root cramfs

The high-level readline API is crazy to use with signals. Fortunately
the library provides low-level rl_callback_* API. In this case we can
use poll() to wait for input and control all signals, etc.
This patch also a little changes fdisk behavior on CTRL+C and CTRL+D.
The signals does not kill fdisk, but forces fdisk to return to the
main menu, if already in the main menu then exit. If the disk layout
has been modified than ask "Do you really want to exit...".
