Make read before write configurable (infrastructure part).

 - Introduce a variable in doit() that allows to influence
   read-before-write and its consequences.
 - Modify build_new_image so that it still works even if the old content
   is not read before.
 - Add copy_old_content() to ease the pain for future patches.

dmi.c: make sure we call isprint() correctly.

ISO C and POSIX require to call ctype functions with values representable
by unsigned char. We have used a char as input so far which might be
negative and hence get sign-extended.
