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.
Corresponding to flashrom svn r1851.
